In a stationary home, you often don't think about your power. The only time it ever needs to cross your mind is when you pay the electric bill if it's not an automatic deduction. But in your RV, you need to hook up your camper to a power outlet when it's parked so you are not draining your batteries. The link from RV to power station brings electrical life to your lights, gadgets, and water system. This vital connection not only needs a holder but a protector for the cord whether it's plugged in or whether you're on the road. This RV camper power cord hatch is just the thing for that job.

Made of tough plastic, this power cord cover is UV safe to protect itself from fading due to the sun. The simple white color blends in with any exterior design scheme while being inconspicuous enough not to draw your eye. Equipped with a snap-lock door to keep the opening shut and the cord protected and connected, this cover will accept up to a 50 amp power cord. The diameter of the inner opening is 3 1/4" and the outer diameter is 5 1/8". The opening on the door for the power cord is about 1".

You don't want your power supply to be suddenly disconnected because your hatch isn't doing its job. With this power cord cover from RecPro, you know that your power will stay up and running, ensuring you a pleasant and relaxing vacation.

Best RV Power Cords, Extension Cords, & Plug Adapters in 2024

(Camp Addict does NOT accept payment from any company to review or endorse their products.)

We'll get right into it... almost all RVs or campers are powered by one of two types of electrical systems.

Your power comes from either your:

• 12-volt system
• 120-volt system

Simply put, the12-volt system is powered from your batteries.

The 120-volt system is the system that needs power from an external power source, an inverter wired into the 120-volt system, or a generator.

You may be using a combination of both systems, depending on how you happen to be camping.

Twist-Lock RV Power Cord

But here's the complication... the power connections at campgrounds are not all alike.

You will find different sized and shaped power receptacles.

Different receptacles mean different amperage ratings, and you have to use the appropriate power source for your rig.

Your RV either requires a 30-amp or a 50-amp plug to connect to the power source.

Power Adapters To The Rescue!

You can use different RV plug adapters to connect when there's no direct match for your RVs power cord. 

You also may need an RV extension cord to reach the power supply, if the distance is too far to reach.

Getting power from a 120-volt source to your RV is kind of a big deal.

You need to make sure you have the right RV power cord for your rig and it needs to be high quality.

This is one place you don't want to be cheap.

You are dealing with high voltage and high amperage.

Below are our #1 picks for the best RV power cords, RV extension cords, and plug adapters.

We give reasons behind every choice made.

RV Electrical Systems

There's SO much to know (insert crying emoji here)! Cords and adapters are only one part of an RV electrical system.

Camco Power Grip Power Cords

• Available with 90º or straight receptacle
• 30-amp power cord available in 2 lengths
• Power Grip ergonomic handle
• Appropriately sized wire for amperage
• Straight receptacle. This style puts strain on the inlet - we recommend the 90-degree receptacle

What is the difference between an RV power cord and an RV extension cord?

The RV power cords reviewed here use a marine-style twist-lock receptacle end.

You only need this product if your RV DOES NOT come with a permanently connected power cord.

An RV power cord is the power cord that originates inside your RV and attaches your RV to power.

They come in 30-amp plug and 50-amp plug versions.

Lengths include 25-foot (30 and 50-amp plug) and 50-foot (30-amp plug only).

If you need additional length, you can get a high-quality RV extension cord.

Marine-Style Twist Lock

They attach to the 30-amp RV plug or 50-amp RV plug marine-style outlet on your RV.

The Camco Power Grip RV Power Cords come in two different styles on the end that plugs into your RV.

Either a straight connector or a 90-degree connector.

We recommend the 90-degree connector.

When the cord sticks straight out, it creates a pull on the plug area.

It's not something critical, but common sense tells us that the 90- degree design is better.

We're not saying that the straight design will eventually fail, but it sure seems more likely than it would on the 90-degree version.

The other end of the RV power cord has a 90-degree connector with a male plug.

Straight Marine-Style Connector

90-Degree Marine-Style Connector

Marine-Style Power Inlet

A 90-degree Connector Would Reduce This Strain

Using Your Power Cord Properly

A 30-amp power cord is easily identifiable with its 3-prong connector.

A 50-amp RV power cord has a 4-prong connector.

( Learn more about RV plug types .)

The male end plugs into the power pedestal, which provides shore power.

Or it plugs into an RV extension cord if you are using one.

How do you know if you need a 50-amp RV power cord or a 30-amp power cord?

Easy- just look at how many prongs your existing power cord has.

3-prongs = 30-amp cord and 4-prongs = 50-amp cord.

Read the guide at the beginning of this page to learn more about how to determine your RV's amperage .

Camco Power Grip handle

Convenience of the Power Grip Handle

When shopping for an RV power cord, you want a grip like the Camco has.

Trust us, your hands and fingers will thank you.

Depending on the tightness of the receptacle that you are plugging into, the connection can be tight.

It takes the leverage and grip afforded by the Power Grip handle to pull it out.

Don't Skimp On Your Power Cord!

A shore power cord is THE vital link between your RV and your power source.

This is one place you don't want to skimp and purchase a cheap piece of caca.

You should use a properly sized QUALITY shore power cord.

If you don't, you can have an electrical resistance issue that causes excessive heat and potentially a fire.

Watch this video to see what happens when you use a cheap, undersized cord.

50-Amp Power Cord With 90 Degree Marine-Style Receptacle

50-Amp Power Cord With Straight Marine-Style Receptacle

Camco Power Grip RV Power Cord Features and Specs:

• High-quality wire (proper wire gauge for the load) and flexible 30 and 50-amp power cords.
• It comes with either a 90-degree female receptacle (recommended) or with a straight female receptacle.
• 30-amp RV power cord comes in either 25-foot or 50-foot lengths. It is a 3-wire conductor (10 AWG) that is rated for 30 amps and 3600 watts.
• 50-amp RV power cord comes in 25-foot length only. It is a 4-wire conductor (3 @ 6AWG and 1 @ 8 AWG) that is rated at 50 amps and 12500 watts.
• Weatherproof connection via the threaded locking ring.
• Power Grip handle ( ergonomic grip ) for easy disconnection (you won't 'kill' your fingers trying to disconnect the cord from the power pedestal or an RV extension cord).
• Storage strap included.

Best RV Extension Cord

Camco Power Grip Extension Cords

• 90º connectors on either end
• Power Grip ergonomic handles
• Available in 2 lengths
• None we can find

When you need an extension cord for your RV, not any old extension cord will do.

These are offered as 30-amp extension cords and 50-amp extension cords.

Camco RV Extension Cords are manufactured with appropriately sized wire for the rated amperage.

They're made with their Power Grip ergonomic handles to make it easier to unplug your cord when needed.

Both ends of this 30-amp extension cord have a 90-degree connector.

(Warning: Do NOT use a traditional extension cord for your RV.)

30-Amp Extension Cord

How do you know if you need a 50-amp extension cord or a 30-amp extension cord?

• 30-amp extension cord = 3 prongs
• 50-amp extension cord = 4 prongs

Read the guide above to learn more about how to determine your RV's amperage .

Extension Cord Basics

Let's say you have a 30-amp plug.

The male end of your 30-amp extension cord plugs into the power pedestal.

The female end plugs into your RV's power cord .

Therefore the extension cord is an extension of your power cord.

The same electrical current that goes through your 30-amp power cord also goes through your 30-amp extension cord.

This means the 30-amp extension cord must be of high quality and must utilize the correct sized wire to be able to handle the electrical load.

Use An RV-Specific Extension Cord

Let us emphasize this point. 

YOU MUST use a high-quality RV specific extension cord that is rated to handle the load your rig uses .

If you don't, you are risking life and property. Cheap RV extension cords DO cause fires.

What Length Do I Need?

You want to only use the minimum length of cord(s) necessary to reach a 120-volt source.

Longer electrical runs can cause a voltage drop, which can be deadly for your appliances and system.

Watch this video to see what happens when you use an extension cord that isn't rated for RV use and is too long.

Spoiler alert: things catch fire...

50-Amp Extension Cord

Power Grip Handle

Both ends of the Camco RV extension cord have a Power Grip, which is an ergonomic handle .

The handle makes it MUCH easier to disconnect.

An ergonomic handle is a finger saver when it comes time to disconnect.

Depending on the tightness of the receptacle that you are plugging into, the connection can be snug.

You will appreciate the leverage and grip afforded by the Power Grip handle.

Camco Power Grip RV Extension Cord Features and Specs:

• High-quality wire (proper wire gauge for the load) and flexible, easy to store both 50 and 30-amp extension cords
• 30-amp extension cord comes in either 25-foot or 50-foot lengths. It is a 3-wire conductor (10 AWG) that is rated for 30-amps and 3600 watts
• 50-amp extension cord comes in either 15-foot or 30-foot lengths. It is a 4-wire conductor (3 @ 6AWG and 1 @ 8 AWG) that is rated for 50 amps and 12500 watts
• Power Grip handle ( ergonomic grip ) on both ends for easy disconnection (you won't 'kill' your fingers trying to disconnect the cord from the power pedestal or an RV power cord)
• Storage strap included

Best RV Plug Adapters

Camco and Conntek Adapters

• Multiple amperage/plug combinations
• Ergonomic handle for easy disconnect
• No negatives

An RV plug adapter allows you to plug your existing cord into an outlet designed for a different amperage.

You may have a 30-amp RV extension cord but it only reaches a 15-amp outlet. What do you do? You use an RV plug adapter.

Below are purchase links for the most common RV plug adapters (dog-bones) you might need.

For additional RV plug adapter choices, please expand the 'continue reading...' section directly below.

You will see all the other adapter choices listed near the bottom of this section.

Seems pretty straight forward, eh?

You should be able to run down to your corner hardware store and cobble something together and call it an RV power adapter, right?

Please don't.

Unless you have a desire to start a fire, you need to buy a quality RV plug adapter.

This video explains why.

Why You Should Buy A Quality RV Plug Adapter

There are two basic types of RV plug adapters:

• hockey puck adapters
• dog-bone adapters.

And if you paid attention to the above video, you know a quality dog bone adapter is best.

Dog Bone Style Plug Adapter

Hockey Puck Style RV Plug Adapter

Dog Bones and Hockey Pucks

There are 15-amp RV plug adapters and 30-amp RV plug adapters in both hockey puck and dog bone configurations.

15-amp to 50-amp RV plug adapters are available in dog-bone style only.

There are 30-amp to 50-amp RV plug adapters in the dog bone configuration.

And finally, there are 50-amp to 30-amp RV plug adapters that also only come in dog bones.

Dog-bone style RV plug adapters have their male ends 180-degrees from the female ends so that when the male end is plugged into the outlet, the female end is pointed towards you (see image below).

This reduces the strain on the adapter when you have a power or extension cord attached to it.

'Y' Adapters

There are other adapters might come in handy.

There are 'Y' adapters that allow you to take power from two plugs (two 'inputs') and plug a single power cord into it (one 'output').

Say for example you pull up to an older campground and the power pedestal only has a 15-amp and a 30-amp RV plug, but you have a 50-amp rig.

There's a 'Y' adapter that lets you plug your 50-amp cord into BOTH the 15 and 30-amp outlets, giving you access to 45 total amps.

A 'Y' Adapter

Or say the pedestal has two 30-amp outlets.

There's a 'Y'-style adapter that allows you to plug your 50-amp RV plug into both 30-amp outlets, letting you access 50 amps of power.

In other words, there are specialty power adapters that you may consider having in your power adapter arsenal.

Additional 'Y' adapter options appear below.

Below we break down the different types of RV power adapters, a little information about each, and provide a link to check out prices and purchase the one(s) you need.

RV Power Cord Adapter Types

The first amperage number in the below options is the amperage of the power socket you have to work with (plug into). 

The second amperage number is the power cord your rig has.

• 10 AWG wire. 14-50P plug (male) and TT-30R receptacle (female)

Camco 55025 Power Maximizer 15 amp & 30 amp to 50 amp 'Y' adapter :

• Designed to have the male ends plugged into both a 15-amp outlet (non-GFCI) and a 30-amp outlet, and the female end plugged into your 50-amp shore power cord (this setup gives you a theoretical maximum of 45 amps - 15 plus 30 amps).
• 15-5P plug (male) & TT-30P plug (male) and 14-50R receptacle (female)
• Power Grip handle on 30- amp male end and 50-amp female end.

Cannot use with a GFCI outlet, which is what most RV parks have on their 15-amp outlets.

Camco Power Maximizer

Conntek 14995 Power Optimizer (cheater box cord) 30 amp & 30-amp to 50-amp 'Y' adapter :

• 2.7 feet long. 10 AWG wire.
• Designed to have the male ends plugged into two 30-amp outlets and the female end plugged into your 50-amp shore power cord.
• (2)TT-30P plugs (male) and 14-50R receptacle (female). Ergonomic handle on all ends. LED power indicator lights on plug end. 

30-amp male plugs have to be on the same neutral in order to have 50-amps of power to use.

30-amp (2) to 50-amp Cheater Cord

Conntek 15961 50-amp to 30-amp adapter & 30-amp 'Y' adapter :

• 3 feet long. 6, 8 & 10 AWG wire.

• 14-50P plug (male ) and (2)TT-30P receptacles (female). Ergonomic handle on all ends. LED power indicator lights on plug end. 

Because you are drawing from a single 50-amp outlet, both 30-amp 'legs' will not be able to pull 30 amps at the same time (as this would equal 60 amps, which, last time we checked, is greater than the 50 amps you have available).

50-amp to 30-amp (2) 'Y' Adapter

Conntek 14963 50-amp to 30-amp adapter & 15-amp 'Y' adapter :

• Designed to 'split' a single 50-amp outlet into 30-amp & 15-amp outlets.
• 14-50P plug (male ) with TT-30P and 5-15R receptacles (female).
• Ergonomic handle on all ends.
• LED power indicator lights on plug end.

50-amp to 30-amp & 15-amp 'Y' Adapter

Ergonomic Cord Grips

All of the RV power and extension cords that we recommend come with ergonomic handles. They make disconnecting MUCH easier.

RV plug ends fit together very snuggly (as they should to ensure a good electrical connection) and therefore can require a bit of effort to pull apart.

The ergo grip handles (Camco calls them a 'Power Grip') give you something to grab ahold of when disconnecting your RV cord.

It puts a whole lot less strain on your fingers. You're welcome. 

Recommendations for Replacement Parts & Accessories

Here are some helpful accessories and other gear for use with your RV power systems.

Products range from storage for your cords, to shore power cord replacements, to upgrading your RV's power inlet.

• New to RVing? Find out what are the RV necessities we recommend you equip your camper with.

RV Cord Replacement Parts

What happens if the dog chews off the end of your power cord? Or, what if the cord gets damaged in the middle?

There are replacements available for plug ends, receptacle ends, and the RV cord itself if yours is hardwired to your rig.

Replacement RV Cord Plugs and Receptacles

Camco makes replacement plug and receptacle ends for both 30-amp and 50-amp RV cords.

They can replace the male ends of shore power cords or both ends of extension cords. This way you don't need to replace the entire cord.

If the cord is damaged enough, just replace it.

We replaced Kelly's 30-amp plug because the outer cable sheathing had 'opened' up exposing the three interior wires and the prongs were a bit burned.

Plus, her old plug didn't have an ergonomic grip, so it was hard for her to disconnect.

There were times she didn't think she would get it separated from her RV surge protector . The replacement was really easy!

Now her cord is repaired and the plug works like new (duh, cuz it is new!).

Kelly's Old, Damaged 30-Amp Plug

Kelly's Brand New 30-Amp Plug

(If you need the female end of an RV shore power cord, also known as a marine-style twist-lock connector, see the section just below.)

30-amp RV plug replacement 'heads' (for the plug, or male end) come in two sizes:

Mini plugs are used for hardwired RV power cords that have the plug end inside a rather small storage door. Or you could use it if you have really small hands. 

All of the Camco RV receptacle replacements come with their Power Grip handles.

This makes it easier to disconnect the 'head' after use.

Replacing The Plug (Male) End Of An RV Power Or Extension Cord

Replacement RV Power (Shore Power) Cords

Conntek makes replacement 30-amp RV power cords and 50-amp RV power cords.

These are for rigs that have a hardwired shore power cord. The replacement cords come in various lengths and have the plug end installed.

There are bare wires on the other end so you can connect it directly to your RV.

30-amp replacement shore power cords use 10 AWG wire and have a right angle TT-30P plug (male) on one end.

Replacement 50-amp RV cords (shore power) use 6 AWG wire (3 wires) and 8 AWG (1 wire) with a right angle 14-50P plug on one end.

NOTE: These replacement power cords don't have ergonomic grips on the plug end.

Replacement RV Power Cord Twist-Lock Ends (Female)

If you have a removable RV shore power cord, there are replacement female ends available However, they are pricey and you're probably better off purchasing an entire new RV power cord.

Marine-style twist-lock female ends are available in both 30-amp and 50-amp RV plug versions.

The 30-amp RV plug version includes both the receptacle and weatherproof cover as a kit.

You have to purchase the 50-amp RV plug pieces separately.

Like we said, just buy a new power cord. We are just showing you the options that are available.

We don't necessarily recommend you pull the trigger on buying these components separately.

SmartPlug - A Better RV Power Cord

SmartPlug White Inlet

The current style of RV power inlets has been around for decades. It has a few major issues.

For one, it's hard to use (line up the L-shaped pin, twist to lock, then tighten down the lock ring after you get it aligned on the threads).

If there is looseness at the electrical connection (a common issue), a massive amount of heat is generated due to resistive heating.

This can cause the plug to melt, or worse. The SmartPlug came onto the market about a decade ago.

It was first marketed to the boating industry to replace the marine-style twist-lock that is also prevalent there.

The SmartPlug system is MUCH easier to use, provides a better electrical connection (eliminates resistive heating), and is all around a better product.

Is it a necessity? No. Could it prevent a fire? Absolutely.

Unlike many cases of a solution looking for a problem, the SmartPlug actually fixes a genuine issue that exists with the traditional RV power inlets.

There are countless examples of a poor electrical connection at the marine-style power inlet causing the female plug to become burned.

This renders it dangerous to use. The worst-case scenario, and this happens, is that the poor connection causes a fire.

SmartPlug Upgrade Kit

If you are upgrading from a fixed power cord to a removable one, it's highly advisable to spend a bit more money and get the SmartPlug conversion kit.

This uses your existing power cord (replacing the receptacle end with a SmartPlug connector) and replaces the power inlet that is part of your RV.

If you are unhappy with your current marine-style twist-lock connector, you can easily switch it out for a SmartPlug (view instructions here).

If you don't feel comfortable dealing with electrical bits on your rig, have a handy friend help you. Or, pay a professional to do the install.

SmartPlug Connector

Some of the features of the SmartPlug include:

• Uses your existing power cord (replaces receptacle end with SmartPlug). It's a direct replacement for the power inlet on your rig (or easily converts your permanently attached power cord to a removable power cord)
• 20 times the electrical contact than the traditional, marine-style twist-lock connector
• Multi-point locking system with three weatherproof silicone seals
• Eliminates the loose connection issue that leads to plug burnout (due to resistive heating)
• No twisting to install - just push straight in until the locking clips engage. Easy!
• No lock rings to mess with or to break off
• SmartPlug combo kits (include power inlet and plug) are available in marine grade stainless steel, or three fireproof plastic colors: white, black, and gray

SmartPlug was kind enough to provide Camp Addict with a 30-amp conversion kit (combo kit) for Camp Addict Co-Founder Marshall.

He converted his existing marine-style twist-lock shore power cord set to the far superior SmartPlug system.

Directly below is a video showing the conversion process and what steps are required.

Hint: It's not that difficult and it's not rocket science! It has been amazing. 

Marshall HATED connecting his marine-style twist-lock power cord to his travel trailer.

It just wasn't easy. And that locking ring? Ugh! It NEVER engaged properly the first time.

The SmartPlug eliminates ALL the hassles of the marine-style connector and is so simple to use. 

We get products to test from time to time, and we let the manufacturer know upfront that we won't review something we don't trust or like.

That's part of the deal.

However, this one was a definite winner.

Marine-Style Twist-Lock RV Power Inlets

If your existing marine-style twist-lock RV power inlet on the side of your rig has seen better days, you can purchase replacement power inlets described below.

If you have a hardwired RV power cord and want a marine-style cord, you can convert it.

Simply use one of the kits below.

Replacement Marine-Style Twist-Lock RV Power Inlets

If your RVs power inlet has seen better days, you can replace it with a new and/or better one.

Replacement RV power inlets that use the marine-style twist-lock (waterproof) connectors come in three different styles:

• traditional square inlet
• contoured inlets
• stainless steel power inlets.

All styles are available in 30-amp and 50-amp versions.

These replacement RV power inlets are fairly easy to replace, assuming you know a thing or two about electricity.

Since we are talking about the main power input of your rig, you want to know what you are doing before you replace the inlet. 

Otherwise, hire a professional.

This makes dealing with shore power cords that much easier.

Fixed RV Power Cord Door

These shore power plug conversion kits come with everything you need to ditch the fixed power cord and turn it into a weatherproof, marine-style power inlet.

Your life will become sooooo much easier.

OK, that's an exaggeration, but at least one small part of your life will become easier - dealing with your RV's power cord.

While installing this conversion kit isn't rocket science (see video below, or you can download the PDF instructions here), you should be fairly handy and not be afraid of electricity.

If you have any doubts about your skill level, have a handy friend help out.

Better yet, hire a professional.

Camco Power Grip Storage Bag

If you like things tidy, you'll like this.

Camco sells a large nylon duffel bag. It has two compartments:

• a large main (zippered) compartment that can hold 50 feet of power/extension cord (or a couple smaller cords)
• a smaller, padded compartment for everything else

Power Cord Storage Bag

Camco Power Grip Cable Lock

Use the Camco Power Grip Cable Lock to 'tie' your Power Grip (or other ergonomic grips) shore power and extension cord.

Or use it to secure your RVs power cord to the power pedestal and/or an RV surge protector.

The Power Lock is a 60' security cable with braided steel wire that has a tough vinyl coating.

One end of the cable is a loop that you pass the other end through (locking pin), then secure it together with the included lock head.

Camco Power Grip Power Ball Lock

Ever wonder how to keep your RVs power cord accessories from being stolen?

Besides the cable lock featured directly above, Camco offers their Power Grip Ball Lock.

It's a spherical clamshell made of tough plastic that locks a connection point (shore power cord to extension cord, or power cord to surge protector).

While this won't secure your cords to a stationary object, it does 'tie' cords together. They cannot be separated so it's harder to walk off with.

As a bonus, the ball keeps connectors off the ground, out of any water in case of rain.

We're not 100% sold on this concept, but hey, it's a thing so we are showing you that it's available. (Lock and keys included.)

7-Way Plug Cover

The end of your 7-pin electrical plug is susceptible to having its electrical connections corrode.

This is because the end is exposed to the elements when it's not in use.

This leads to electrical connections not working, and therefore trailer lights, battery charging, and maybe your brakes not functioning properly.

You can keep dirt, rain, and critters out by using the 7-pin plug cover from GR Innovations.

This made in the USA cover is a must-have for all travel trailer owners with a 7-pin style connection to the tow vehicle.

GR Innovations supplied Camp Addict with a 7-pin plug cover to test out.

Camp Addict co-founder Marshall has been happily using it and it's working exactly as advertised.

Camco Power Cord Strap

Neat freaks- check this out!

If you don't want to spring for Camco's above power cord, their simple strap might be right for you.

This nylon strap with carrying handle has a plastic quick-disconnect so that you can easily wrap it around your neatly coiled cord. There's not much else to it. 

Simple. Effective. Get one! (or two, or three...)

Authors: Kelly Beasley & Marshall Wendler

Kelly and Marshall co-founded CampAddict.com and ran the business until April 2024 when they sold to Schwalm Inc. They have been full-time RV'ers since 2014, particularly enjoying the freedom of boondocking. Both of them transitioned into #vanlife mode in December 2020. They are now plotting their next adventure as they set off to explore new frontiers.

I have a living quarters horse trailer. The power is set up for 30 amp. The original plug looked like the one “Kelly” had in this article. The plug pulled apart from the sheathing exposing the individual wires. I replaced it with the Camco mini to ease unplugging. The mini did not quite fit all the way into the hatch, the slight protrusion seemed ok. The hatch lid had broken off years ago and the cord always stayed put…. Until yesterday. Upon returning home, I found the cord without a connector stuck on the folded stair with about 4 ft of cable protruding. At some point on our return home yesterday on a 240 mile trip, the cord wiggled out and the connector sheared right off. The cord end must have flipped up and caught on the folded stair pretty quickly after the end sheared off as there is very little wear on the cable. The hatch is 2″ deep, 2.7″ ID and the hole in the side of the trailer is 3″. I’ve looked at Home Depot, Lowes, Amazon, and internet searching and the one that looks promising is the Conntek 30 amp . With the original plug I also had a terrible time disconnecting it. The Conntek looks like it would be difficult as well. Might you have any other suggestions?

Thanks for checking out Camp Addict!

That sounds like the kind of excitement one doesn’t need when towing a trailer! I’m glad to hear that nothing happened other than the plug end when on a trip of its own.

I wish trailer manufacturers would make a shore power compartment that worked in real life and gave plenty of room for the plug end, etc.

If you search for “30 amp replacement plug male” on Amazon, there are a ton of choices. Many have a pull of some sort, like the Camco one we suggest. Trouble is the pull makes the plug bulkier, so depending on the cord compartment size/layout, it might not fit in there. So it become an issue of what is more important – being able to disconnect the cord easier via a pull, or foregoing the pull and having a more compact plug end that fits into the compartment.

Big help, right?

I hope you find a plug that will work best for your situation so that you don’t have any more of this type of excitement in the future.

I have a 50 amp female to a 30 amp and 20 amp male splitter. I want to connect the 50 amp female to the trailer and the 30 amp male to my 3500 generator and the 20 amp male to my 2000 generator. I will only run 1 generator at a time. Will I get a feedback from the running generator to the “off” generator? I assume the splitter I purchased was designed for this application.

Hi Douglas,

As we explain in the “Y Adapters” section of the “Best RV Plug Adapters” review box above, the adapter you mention is “Designed to have the male ends plugged into both a 15-amp outlet (non-GFCI) and a 30-amp outlet, and the female end plugged into your 50-amp shore power cord (this setup gives you a theoretical maximum of 45 amps – 15 plus 30 amps).”

In other words, it’s used to combine two shore power sources, giving you a theoretical amperage that is higher than one of the single sources.

It isn’t intended to be used with generators. I have no idea what would happen in the use case that you mention.

Why do you want to use a Y adapter? If you are running one generator at a time, why not just plug your RV’s power cord into the generator that you are going to use?

I’m wanting to buy an adapter to convert a 30amp to a 50amp is there an advantage to buying a cord adapter versus a plug adapter?

Great question!

So the hockey puck style adapter ‘extends’ straight out from the receptacle and then your RV power cord connects to it. This creates a ‘stacked’ plug setup that usually is horizontal to the ground. The weight of the heavy gauge power cord hanging off this may cause the hockey puck adapter to want to come out of the power pedestal. Especially if the pedestal outlet plug has some looseness to it (which is common with age/use).

The cord style adapter has a 90 degree ‘turn’ at the male end where it plugs into the power pedestal, which means the weight hangs down immediately. With this setup, you will rarely have the cord wanting to pull itself out of the power pedestal.

Plus, for what it’s worth, I just like the ‘feel’ of the cord style adapters better. Not sure that means anything, but I’m just more comfortable using this style adapter.

I recently bought a travel trailer that is 30 amps. It included a 25′ 10 gauge, 30 amp power cord. One of the campgrounds I go to I need a much longer cord. Is it ok to use a 25′ extension instead of purchasing a 50′ power cord. I was told it is not good to add an extension to an RV cord.

First, we want to thank you for reaching out looking for an answer to this.

Electricity is so dangerous, and so many people get it wrong! So we’re glad you’re seeking help.

To answer your question, we recommend you get the shorter 25’ 30 amp (made for) RVs extension cord.

This way you aren’t having to always deal with such a long 50’ cord.

AND using shorter cord is always better. There’s less resistance for the electricity to pass through.

You should NOT use a regular household extension cord. This may be what that someone was referring to.

So no, it’s not true that you should not use an extension cord. It’s best if you don’t have to to use one. But if you cannot reach otherwise, then an extension cord made for RVs with the appropriate gauge will be just fine!

Thanks Diane, have fun with your explorations and stay safe out there.

I am trying to find an RV adaptor splitter that has a 30 amp male that plugs into campground electrical box and splits into a 50 amp to camper and a 110 volt to be used for porch lights. Is there such a splitter? Any help would be awesome.

Not that I’m aware of and here’s my take on why.

You are asking a 30amp power source to supply power to a 50 amp rig, so you are already running a potential power deficit. To ask the 30 amp power source to additionally supply a potential 15 amps of power (the standard household outlet that you want to run porch lights from) would mean a further potential power deficit.

In other words, you would be asking a 30 amp power source to supply up to 65 amps of power (50 amp + 15 amp). No manufacturer in their right mind would put out a product capable of this. Can you say fire liability?

You can get this type of a setup going from a 50 amp power source to a 30 amp RV plug and a 15 amp household plug, but not the other way around.

Just keep in mind that when you plug a 50 amp RV into a 30 amp outlet you have to be very careful to limit the number of high power consuming devices at one time to not trip the power pedestal’s 30 amp circuit breaker.

I assume you are wanting to put some sort of 120-volt patio lights around your RV? Why not just plug them into your RV’s external 120-volt power outlets that are being fed when your rig is plugged into the 30 amp outlet?

I’m new to campers. I have a 1999 keystone montana 3250rk.

I found a Coleman 10/3 STW 30 amp cord. My camper is a 50 amp 3 pole 4 wire hook up.

Will this cord run my camper or will it cause problems?

You have a 50-amp rig. You need to use a 50-amp extension cord.

It’s VERY important that the extension cord you use is rated to handle the maximum load your RV can draw, or bad things can happen.

Plus, if you are trying to use a 30-amp cord with a 50-amp rig, you are going to have to use a 30-amp to 50-amp adapter where the extension cord plugs into your rig. This is one more potential failure point/cause of problem in your RV’s power supply. It’s best to eliminate as many of these potential ‘issue’ spots as possible.

Welcome to RVing! I know it’s really overwhelming, but you are doing the right thing and asking questions.

Have a question, is there a highly recommended power cord splitter? An rv and toy hauler trailer sharing a space at rv park

Hey Stephanie,

Please tell me that the two RVs are sharing at least a 50-amp connection. There is no scenario that ends well if two RVs are trying to share a single 30-amp connection. You will be having to do some super energy management (i.e. not using any appliances with appreciable amperage draw) if you want to share a 30-amp outlet.

A single RV will require, at the very least, a 30-amp outlet.

OK, assuming you are sharing a 50-amp outlet, you are still going to have to be very mindful of power use. But it is doable. If you are careful and aware.

There are two Conntek products listed at the very bottom of the RV Plug Adapter section of this page that handle splitting a single 50-amp supply into two. One splits it into two 30-amp plugs (you won’t be able to use 30-amps from each at one time due to simple math – 30+30=60 which is more than the 50-amps available). The other splits into a single 30-amp and a single 15-amp plug.

Best of luck sharing a power supply. BE VERY CAREFUL!

Thank you for your response and I found out that the park pedastal has a 30amp and a 50 amp plug in and I will be getting a dog bone adapter for my 30 amp to plug into the 50 amp if the other person will be using the 30 amp. Hope I am understanding this subject

It sounds like you are getting it, Stephanie. Yes, if you have a 30-amp RV, you would need a dogbone adapter to connect to the 50-amp input. Remember, the 50-amp plug has four prongs while the 30-amp plug has three prongs. Easy peasy!

Hello Camp Addict, I was wondering how I could use an abandoned 30 amp 3 wire disconnect at my home to install a outlet to power my 30 am p travel trailer? I did buy a 50 covered outlet for the house just in case I ever wanted to upgrade the trailer, which has lugs for 4 wires.The 3 wires are 2 hots and a ground as you mentioned with the dryer outlet (not to use). how do these 50 amp 4 wire to 3 wire premade adapters work? Thanks for any help you can offer,

I have no clue if you can do what you are asking. I know nothing about how houses are wired electrically and wouldn’t even know where to start. It’s best to talk to a qualified electrician about this, but you do need to be crystal clear about what you are looking to do. Wire an outlet for an RV and not a dryer.

Ok, thank you.

Thank you for this great article and the other useful information on this site. I’m a new rv owner, and have a couple questions.

You recommend the Camco dogbone adaptor for 30 to 15 amp, but also say that Conntek is good for other connectors. Is their 30 to 15 amp also a good choice? I’m asking because the 15 amp plug on the Conntek is smaller, making it easier to store.

My second question is about using a good quality 10 gauge regular extension cord to plug into a house outlet. The connection would be my rv power cord into a dogbone adapter into the extension cord into the outlet. My impression from your article is that it’s better to use do rv cord into rv extension cord into the dogbone adapter, straight into the house outlet – but I don’t understand why, as long as the gauge of the extension cord is 10g.

Thanks for you help, and it’s so cool you answer questions! AC

Glad you like Camp Addict. Thanks for visiting and for the question!

The Conntek 15200 (30 amp female to 15 amp male) dog bone would be a fine choice. I see that is may have a slightly smaller 15 amp end, but I seriously doubt you are going to gain any storage space using this dog bone over the Camco one. Either is a fine choice.

If you could find a 10 gauge heavy duty, outdoor use household extension cord that is of high quality maybe you could get away with using it. Not sure why you would want to buy one of these instead of an RV specific one. A quick check of prices showed the Camco 25 foot 30 amp extension cord is as inexpensive, or even costs less, than the household specific ones on Amazon.

I hope you aren’t planning on running high energy use appliances in your RV via a 15 amp connection. You may be able to run the AC by itself. Or the electric water heater by itself. But you aren’t going to have too much luck running both at once (or with other 120 appliances)

There’s a reason why RVs come with a minimum of a 30 amp input. 🙂

Good luck and Camp On!

You guys explain things beautifully !!! ???? Mike Clary San Antonio, Texas

Well, thank you very much! Glad we are easy to understand- nothing easy to understand (to me) about electricity! It was a tough subject to cover. More for me than for Marshall. Cheers!

We camp at a location where our 30 amp trailer is about 120 ft. from the 30 amp power source. Our electrician said we should get an “SO” cable to run to the trailer. Are RV extension cords good for this distance instead? Is an SO cable appropriate?

120 feet is a really long distance to use an RV extension cord. In fact, you’d have to use at least 2 RV extension cords to travel this distance. They really aren’t intended for this long of a run.

The problem is voltage drop over this long distance using the gauge of wiring that a 30-amp RV extension cord has. In the case of the extension cords reviewed on this page, the gauge of wire used is 10 AWG. Over a 120 foot run, assuming a 30-amp load (which would be the max your rig is capable of ‘using’ since it’s a 30-amp rig), we are talking around a 6% voltage drop. This is too much.

I used this online voltage drop calculator to figure out this voltage drop.

You really want a low single digit voltage drop, so no more than say 2-3% is ideal. For a 120 foot run you’d want to use no smaller than a 7 AWG wire.

I assume that is why your electrician suggests an SO (common type of wire that can be buried) wire for this run. Assuming they are wanting to use a gauge of wiring that is appropriate.

I’d listen to your electrician here, and go with a properly sized wire rather than trying to string together a couple/few RV extension cords. You need to be concerned about voltage drop over this length of wiring run, so it’s best to do things right.

Thanks for the question, and Camp On!

“Trailers = 2 electrical systems A 120-volt system that is used when you plug into shore power. A 120-volt RV system running things from your RV battery.”

Yes, it was a typo! ???? Thank you very much for pointing it out! It has been corrected. Electricity is confusing enough without us making a mistake like that! Grrrr. Thanks again- you’re the best! ????

Thank you so much for sharing your wisdom. I have not purchased my rv yet, but I’m trying to do all my research and get my ducks in a row before purchasing. I plan on being a fulltime. I have already saved this site for reference!!!

Thank you so much! Glad to be here to serve you.

Having a plan is great- plan, and you shall follow. Good luck with picking your new RV!

We sure hope to get more and more categories out there on this site. We are working on an RV manufacturer reference post, which might help you in your search.

Cheers, and have fun with it all!

Thank you for your site. My RV is hooked to my sons house and I’m going to live in it, some of the time! However, some of the major appliances don’t work. I think I’ve figured it out, thanks to your article! The extension cord I bought is a 15 amp cord. Duh. I knew it would be something so simple it would embarrass me. I know very little about electricity and even less about rvs! I am learning. It’s an older RV, with few bells and whistles. I’m assuming it’s a 30 amp. Should I buy a cord capable of 50 amps, simply to be sure?

Thank you for the comment, we all appreciate a little massage now and again! : )

Ok, so yes, electricity can be complicated and scary. You will get used to it as you get more comfortable using your part-time home, we promise! (I wish Camp Addict had been around when I hit the road!)

The good news is your question should be an easy one to answer. First question- does your RV have a power cord connected to it? Let’s start from there!

Waiting for your reply. ????

Yes, it does…. but it’s not long enough to reach the house.

Ok, how many prongs are on the end of it? Three or four? (Make SURE there’s no short adapter connected to the end.) If 3, it’s a 30 amp. If 4, it’s a 50 amp RV. Simple as that!

Yes. But, it’s not long enough

Ok, no worries. This is easy! Look at the end of your power cord. If it has three prongs, it’s a 30-amp RV. If it has 4 prongs, it’s a 50-amp RV.

Make SURE there is not an adapter connected to the end of your power cord. (You could have a 50-amp to a 30-amp ‘dogbone’ adapter that makes you think you have a 30-amp RV instead of a 50-amp RV.)

Also, make sure the power cord you DO get is made for RVs. You can find these on Amazon or at your local camping store.

Let us know what you find your RV to be, ok?

Thank you soooo much. I was going to have to hire an RV set up guy to come out. I’d of sure been sad if I paid $100 for the trip and he just changed the cord! Lol

Of course! What did you find that you have? 30 or 50?

I don’t know yet. LOL. I am not in the area where the RV is right now. My son has been trying to get it set up and we have not been able to get it done. The information that you have given me is going to be so helpful thank you

Ok, good luck with it all! Let us know how it works out!

Awesome information, especially for a newbie like me. Purhased many of the items based on your recommendations.

That’s great to hear! And thank you for supporting Camp Addict, we truly appreciate you!

Great and concise information!!! Thank you.

Glad you found the RV power cord page helpful, Kathryn. You are very welcome and Camp On!

Everything I wanted to know! Thank you RV breaking it down! IT may save a Rig or a LIFE!

We sure hope so! Thanks for finding us and for taking the time for the nice comment. Go ahead and Camp On SAFELY, Patricia!
