Let’s get started.

One of two kinds of electrical systems is used to power practically all RVs and campers.

Your source of power is either:

  • 12-volt battery
  • 120-volt apparatus

Simply explained, your batteries are used to power the 12-volt system.

The 120-volt system is the one that requires electricity from a generator, an inverter that is plugged into the 120-volt system, or an external power source.

Depending on how you’re camping, you can be using both systems simultaneously.

RV Power Cord with Twist-Lock

The problem is that different campsites have different power hookups.

Power outlets come in a variety of sizes and shapes.

You must utilize the proper power supply for your equipment since various outlets have varying amperage ratings.

To connect to the power supply, your RV needs either a 30-amp or a 50-amp plug.

Rescue with Power Adapters!

When there isn’t a straight match for your RV’s power chord, you may connect using various RV plug adapters.

If the distance is too great, you may also require an RV extension cable to get to the power source.

It’s somewhat of a huge deal to power your RV with a 120-volt supply.

You must ensure that you have the appropriate, high-quality RV power cable for your vehicle.

You don’t want to be cheap in this situation.

High voltage and high amperage are present.

Here are our top selections for the best RV extension cables, plug adapters, and power cords.

We explain each decision we make.

Electrical Systems for RVs

(Insert sobbing emoji here) There is SO much to learn! One component of an RV’s electrical system is not only cords and adapters.

Read our RV Electrical Systems Guide to find out everything else you need to know about your RV’s electrical system.

Reviews Of RV Power Cords, Extension Cords, And Plug Adapters

#1. Camco Power Grip Power Cords – Best RV Power Cord


  • Available with a straight or 90-degree receptacle
  • Two lengths of the 30-amp power cable are offered.
  • Ergonomic Power Grip handle
  • The right-sized wire for the amperage


  • A straight container. This design strains the intake, thus we advise using the 90-degree receptacle instead.

Read Our Review Of The Camco Rv Power Cord.

An RV power cable is the electrical cord that comes from within your RV and connects it to a power source.

Versions with 30-amp plugs and 50-amp plugs are available.

There are 25-foot (30 and 50-amp plug) and 50-foot lengths available (30-amp plug only).

A top-notch RV extension cable is available if you want more length.

Twist Lock, Marine-Style

The marine-style twist-lock receptacle end is used on the RV power cables we tested here.

They hook into your RV’s marine-style outlet with a 30-amp or 50-amp RV plug.

On the end that connects into your RV, the Camco Power Grip RV Power Cords are available in two distinct designs.

Either a 90-degree connection or a straight connector is required.

The 90-degree connection is recommended.


A pull is produced on the plug area when the cable protrudes straight out.

Even if it’s not crucial, common sense tells us that the 90-degree design is preferable.

Although we don’t foresee the straight design failing in the future, this looks more possible than it would on the 90-degree variant.

The RV power cord’s opposite end features a male plug with a 90-degree connection.

How to Use Your Power Cord Correctly

The 3-prong connection on a 30-amp power cable makes it simple to identify.

A 4-prong connection is found on a 50-amp RV power cable.

The power pedestal, which delivers shore power, is plugged in using the male end.

Or, if you’re using one, it connects into an RV extension chord.

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

It’s simple—just count the number of prongs on your current power cable.

30-amp cords have three prongs, whereas 50-amp cords have four.

For further information on how to calculate the amperage of your RV, see the advice at the top of this page.

Handle with Camco Power Grip

The Power Grip Handle’s Convenience

You want a grip like the Camco offers when looking for an RV power cable.

Your fingers and hands will appreciate it, we assure you.

The connection may be tight depending on how tightly the socket you are plugged into is closed.

To pull it out, you need the leverage and hold that the Power Grip handle provides.

Make Sure Your Power Cord Is Quality!

The most important connection between your RV and your power source is a shore power wire.

You shouldn’t cut corners and buy a subpar piece of caca here.

Use a QUALITY shore power cable that is the right size for your device.

If you don’t, you risk an electrical resistance problem that produces too much heat and might start a fire.

See what happens when you utilize a cheap, inadequate cord by watching the movie.

The wire used in Camco RV Extension Cords is the proper size for the stated amperage.

To make it simpler to unhook your cable when necessary, they are constructed with Power Grip ergonomic grips.

This 30-amp extension cable has a 90-degree connection on both ends.

(Caution: Your RV should NOT be powered by a conventional extension cable.)

Extension cord, 30 amps

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


  • 3 prongs for a 30-amp extension cord
  • 4 prongs on a 50-amp extension cable

Basics of Extension Cords

Consider that your plug is a 30-amp one.

Your 30-amp extension cord’s male end connects into the power pedestal.

The female end connects into the power cable of your RV.

As a result, your power cable is extended by the extension cord.

Your 30-amp power cable and 30-amp extension cord both carry the same amount of electrical current.

This implies that in order to manage the electrical load, the 30-amp extension cable has to be of excellent quality and have the proper size wire.

Use An Extension Cord Designed for RVs

Let’s make sure to stress this.

You MUST utilize an extension cable designed specifically for RVs and rated for the weight your vehicle uses.

You put property and human life at danger if you don’t. Poor quality RV extension cables CAN cause fires.

Do I Need What Length?

Only utilize the shortest cord(s) required to connect to a 120-volt source.

Longer electrical runs may result in a voltage drop, which may be fatal to your system and appliances.

See what happens when you use an extension cable that is too long and not intended for RV usage by watching the movie.

Warning: There will be spoilers.

Extension Cord 50 Amp

It seems rather simple, doesn’t it?

You ought to be able to quickly assemble something at the local hardware shop and refer to it as an RV power adaptor, right?

Please refrain.

You must get a high-quality RV plug adaptor unless you want to ignite a fire.

See why in this video.

Reasons To Purchase A High-Quality RV Plug Adapter

Are dog bone RV electrical adapters dangerous? – RVtravel

RV plug adapters come in two different categories:

  • Puck adapters for hockey
  • Dog-bone connectors

And if you saw the video up above, you know the best dog bone adapter is a good one.

Dog Bone Style Plug Adapter
RV Plug Adapter Shaped Like a Hockey Puck

Hockey Pucks And Dog Bones

Both the hockey puck and dog bone shaped 30-amp and 15-amp RV plug adapters are available.

Only dog-bone-shaped 15-amp to 50-amp RV plug adapters are offered.

The dog bone design of RV plug adapters ranges from 30 to 50 amps.

Finally, there are RV plug adapters that range from 50 to 30 amps but are only available in dog bones.

RV plug adapters in the dog-bone design feature male ends that are 180 degrees apart from the female ends, ensuring that the female end is facing you when the male end is inserted into the outlet (see image below).

When a power or extension cable is connected to the adapter, this lessens the pressure on the device.

A “Y” Adapter

There are other adapters available that could be useful.

There are “Y” adapters that let you connect a single power cord to one “output” while drawing power from two plugs simultaneously (i.e., two “inputs”).

Consider the scenario when you arrive at an older campsite and find that the power pedestal only has a 15-amp and a 30-amp RV connection, even though your vehicle has 50 amps.

You may access a total of 45 amps by using a “Y” adapter to put your 50-amp wire into BOTH the 15 and the 30-amp outlets.

The “Y” Adapter

Or, suppose there are two 30-amp plugs on the pedestal.

You may connect your 50-amp RV plug to both 30-amp outlets using a “Y”-style adapter, giving you access to 50 amps of electricity.

so on.

In other words, you could think about include some specialised power adapters in your collection.

Below are several more ‘Y’ adapter possibilities.

The numerous varieties of RV power adapters are described here, along with some information on each, and a link to check pricing and buy the one or ones you need.

Types of RV Power Cord Adapters

#4. Ergonomic Cord Grips

All of the extension and power cables for RVs that we suggest include comfortable grips.

They significantly simplify disconnection.

RV plug ends are very snugly fitting (as they should be to provide a proper electrical connection), making it difficult to separate them.

When unplugging your RV cable, you have something to grasp onto thanks to the ergo grip handles (Camco refers to them as a “Power Grip”).

It significantly lessens the stress on your fingertips.

I’m happy to help.

Replacement Parts and Accessory Recommendations

Here are some useful extras and equipment for your RV’s power systems.

Products include upgrades for your RV’s power intake as well as storage for your cables and new shore power cords.

#1. Replacement Parts For RV Cords

What would happen if your dog bit the end of the power cord? What if the cable is destroyed in the center, for example?

If your RV cable is hardwired to your vehicle, there are new plug ends, receptacle ends, and RV cords available.

Plugs & Receptacles for Replacement RV Cords

For both 30-amp and 50-amp RV cables, Camco manufactures replacement plug and receptacle ends.

They may swap out either the male ends of extension cables or the male ends of shore power lines.

You may avoid having to replace the whole cable in this manner.

Simply replace the cable if it is sufficiently damaged.

Kelly’s 30-amp plug needed to be changed since the prongs were a little scorched and the outside cable wrapping had ‘opened’ up, revealing the three inside wires.

She found it challenging to disengage since her previous plug lacked an ergonomic grip.

She sometimes doubted that she would be able to detach it from her RV surge protector.

It was quite simple to replace.

Her cable has been fixed, and the plug—which, of course, is brand new—works flawlessly now.

Old, faulty 30-amp plug from Kelly
Brand-New 30-Amp Plug from Kelly

(See the part just below if you require the female end of an RV shore power cable, often known as a marine-style twist-lock connection.)

Replacement “heads” (for the plug, or male end) for 30-amp RV plugs are available in two sizes:

  • Normal
  • Mini

Hardwired RV power lines with the plug end within a relatively modest storage door are utilized with mini plugs.

Or, if you have really little hands, you may utilize it.

The Power Grip handles are included with each and every Camco RV receptacle replacement.

As a result, it is simpler to detach the “head” after usage.

Twist-Lock Ends for Replacement RV Power Cords (Female)

Replacement female ends are available for detachable RV shore power cords, but they are expensive, so it would probably be wiser to buy a brand-new RV power chord instead.

Both 30-amp and 50-amp RV plug versions of marine-style twist-lock female terminals are offered.

The waterproof cover and receptacle are both included in the package for the 30-amp RV plug.

The 50-amp RV plug components must be purchased individually.

Buy a fresh power cable, as we previously advised.

We are only presenting you with your alternatives.

We don’t necessary advise you to make the purchase of these parts individually.

#2. A Better RV Power Cord Is SmartPlug

White SmartPlug Inlet

RV power inlets have existed in their present form for many years.

It has a few serious problems.

It’s challenging to use, for starters (line up the L-shaped pin, twist to lock, then tighten down the lock ring after you get it aligned on the threads).

Due to resistive heating, a significant quantity of heat is produced if the electrical connection is slack (a typical problem).

This may result in the plug melting or worse.

About ten years ago, the SmartPlug first appeared on the market.

To replace the common marine-style twist-lock there, it was first sold to the boating sector.

The SmartPlug technology offers a superior electrical connection (eliminating resistive heating), and is an all-around better product.

It is also MUCH simpler to operate.

Is it required? No.

Can it put out a fire? Absolutely.

The SmartPlug, in contrast to many instances of a solution seeking a problem, genuinely resolves a legitimate issue that occurs with the conventional RV power inlets.

There are several instances when a bad electrical connection at the marine-style power input results in a charred female connector.

Because to this, using it is risky.

The worst-case situation is that the faulty connection starts a fire, and this does happen.

Upgrade Kit for SmartPlug

It is strongly advised to invest a little extra money and get the SmartPlug conversion kit if you are switching from a fixed power connection to a detachable one.

This replaces the power inlet that is built into your RV by using your current power cable and switching out the receptacle end for a SmartPlug connection.

You can quickly replace your present marine-style twist-lock connection with a SmartPlug if you don’t like it (view instructions here).

Have a handy buddy assist you if you don’t feel confident working with electrical components on your equipment.

Or hire a specialist to complete the installation.

Connector for SmartPlug

The Following Are Only A Few Of The Smartplug’s Features:

  • Utilizes the current power cord (replaces receptacle end with SmartPlug). It is a direct replacement for your rig’s power inlet (or easily converts your permanently attached power cord to a removable power cord)
  • Compared to the conventional marine-style twist-lock connection, there are 20 times more electrical contacts.
  • Three waterproof silicone seals on a multi-point locking system
  • removes the problem of weak connections that causes plug burnout (due to resistive heating)
  • Simply press straight in until the locking clips engage to install without twisting. Easy!
  • There are no lock rings to fiddle with or snap off.
  • Available in three fireproof plastic colors: white, black, and gray, SmartPlug combination kits (which contain a power inlet and plug) are made of marine grade stainless steel.

A 30-amp converter kit (combo kit) for Camp Addict Co-Founder Marshall was kindly provided by SmartPlug.

He upgraded to the far better SmartPlug system from his old set of marine-style twist-lock shore power cords.

The conversion procedure and the stages needed are shown in the video just below.

Hint: It’s not very tough or complicated.

It has been incredible.

Marshall HATED tying his travel trailer’s marine-style twist-lock power connection to it.

It simply wasn’t simple.

The locking ring, too? Ugh! It almost never works correctly the first time.

The marine-style connector’s problems are ALL eliminated by the SmartPlug, which is also very easy to use.

We sometimes get things to test, and we always let the maker know that we won’t evaluate anything we don’t like or trust.

The arrangement includes it.

But this one was unquestionably a success.

#3. Twist-Lock RV Power Inlets in the Marine Style

You may buy new power inlets as stated below if the marine-style twist-lock RV power inlet on the side of your vehicle needs to be replaced.

You can convert an RV power cable if you already have one and desire a marine-style cord.

Use one of the kits listed below.

Twist-Lock RV Power Inlets in Replacement, Marine Style

You may swap out your RV’s power inlet with a brand-new or improved one if it has seen better days.

There are three main types of replacement marine-style twist-lock (waterproof) connectors for RV power inlets:

  • Customary square inlet
  • Rounded inlets
  • Power inlets made of stainless steel

Both 30-amp and 50-amp variants of each type are offered.

If you know a little bit about electricity, replacing these replacement RV power inlets should be very simple.

Before you change the inlet, you should be knowledgeable about what you’re doing since we’re discussing the primary power input of your apparatus.

Otherwise, see a specialist.

Conversion Kits for Marine-Style Twist-Lock RV Power Inlets

Instead of using a permanent RV power cable, you may switch to a marine-style, detachable twist-lock connection.

Dealing with shore power lines is now considerably simpler as a result.

Rv Door With Fixed Power Cord

These conversion kits for shore power plugs include everything you need to do rid of the permanent power line and transform it into a waterproof power inlet that looks like a marine inlet.

It will be so much simpler for you.

Although that exaggeration, at least one little aspect of your life will be made simpler—handling the electrical wire for your RV.

Although it’s not difficult to install this conversion kit (see the video below, or go here to receive the PDF instructions), you should be somewhat handy and not frightened of electricity.

Ask a handy buddy to assist if you are unsure about your degree of expertise.

Hire a specialist instead.

#2. Power Grip Cable Lock by Camco

To “tie” your Power Grip (or other ergonomic grips) shore power and extension cable, use the Camco Power Grip Cable Lock.

Alternately, use it to fasten the power cable of your RV to a power pedestal or an RV surge protector.

A 60′ security cable with braided steel wire and a durable vinyl covering is called the Power Lock.

The cable has a locking pin on one end, which you pass through before joining the cable with the lock head that is also provided.

#3. Power Grip Power Ball Lock by Camco

Ever wonder how to prevent theft of the accessories for your RV’s power cord?

In addition to the cable lock seen above, Camco also sells their Power Grip Ball Lock.

It is a plastic clamshell that is round and locks a connection point (shore power cord to extension cord, or power cord to surge protector).

Your ropes will be “tied” together, but not to a fixed object, by doing this.

It is more difficult to flee with them since they cannot be split apart.

In addition, the ball elevates connections off the ground, keeping them dry in the event of rain.

Although we’re not quite convinced on the idea, we’re displaying it to you nonetheless since it exists.

(Keys and lock are included.)

#4. Plug Cover for 7 Ways

Your 7-pin electrical plug’s end is vulnerable to corroding electrical connections.

This is due to the fact that when it is not in use, the end is exposed to the weather.

This results in broken electrical connections, which affects battery charging, trailer lighting, and possibly brake performance.

Use the 7-pin plug cover from GR Innovations to keep dirt, rain, and animals out.

All travel trailer owners with a 7-pin type connection to the tow vehicle need this manufactured in the USA cover.

Camp Addict received a 7-pin plug cover to test from GR Innovations.

Marshall, a co-founder of Camp Addict, has been using it with pleasure, and it performs as promised.

#5. Power Cord Strap by Camco

Check this out, cool freaks!

If you don’t want to spend the extra money for Camco’s above power cable, their straightforward strap may be the best option.

You can effortlessly wrap this nylon strap around your neatly coiled rope thanks to its plastic quick-disconnect and carrying handle.

Not much more is involved.

Simple. Effective. Buy one! (Or two, three, etc.)

We’re almost done now, kids.

When it comes to RV power cables, extension cords, and plug adapters, there is more than meets the eye.

Primarily, you want to safeguard your RV by purchasing extension cables and adapters that are rated for the power capacity they will be required to support.

Please read the previous comments below before asking a question if you have one.

Then, feel free to inquire if you have a question that isn’t covered here.
