Best RV Power Cords & Adapters For 2023

We’ve taken a look at several leading products and determined that the Camco 25′ PowerGrip Heavy-Duty model is the best RV power cord on the market right now.

Why do you need an RV power cord in the first place? We’ve wondered the same thing. It turns out that an RV’s electrical system offers both 12-volt and 120-volt components. The 12-volt system is powered by the RV’s onboard batteries, while the appliances that run off a 120-volt connection require an outside source—for example, a generator or external power hookup.

However, some RVs might require a different amperage than others. Moreover, the source of shore power might be too strong or too weak for your RV’s electrical system. That’s when an RV power cord comes in handy.

For your convenience, we’ve also included a few of the best RV extension cords on our list. These are essential for reaching outside power sources that are located a bit too far away from your RV’s parking spot.

Our favorite aspect of the Camco Dogbone 30-Amp Male to 50-Amp Female Adapter is the handle design. Crafted from polyvinyl plastic, they’ll prevent you from accidentally shocking yourself. Since they face away from each other, they also reduce strain to the middle section of the adapter.

  • Longer than some similar adapters

Buying Guide

What To Consider When Buying An RV Power Cord Or Adapter

Type Of System

First of all, consider whether your RV’s electrical system requires a power supply of 30 or 50 amps. That will help you narrow down your search.

30 amp RVs come with a single 120-volt electrical circuit. These can handle a total wattage of up to 3,600. These are common in smaller travel trailers and RVs and should be able to handle a refrigerator, microwave, television, and air conditioning unit. They’re also sufficient for powering electronic devices such as laptops and cell phones.

50 amp models, meanwhile, offer two separate 120-volt circuits and can handle a maximum of 12,000 watts. More often found in luxury RVs, they can deliver energy to larger refrigerators, dishwashers, washers and dryers, entertainment centers, and electric fireplaces.

If you’re not sure what type of rig you have, take a look at your power cords. 30A cords have three prongs, while 50A cords have four.

Type Of Receptacle

Some adapters are designed to plug into straight receptacles, while others are compatible with 90-degree input stations. Pay close attention to the amperage rating when making your choice, since the shape of the receptacle could influence this number.


RV power cords are available in a variety of lengths. Most companies offer a choice between 15-, 25-, 30-, and 50-foot cords, or some combination thereof. Which one you buy depends on how much space you have to store it and how close you are to the outside power source.


Try to buy the best RV adapter or power cord that you can afford. Fortunately, many of these units are available at a reasonable price.

The longer the cord is, the more you can expect to spend, so you might want to consider a shorter one if you’re on a budget. 50-amp models are also more expensive than their 30-amp counterparts.

How It Works

Before you can select the best RV power cord or adapter, you’ll need to familiarize yourself with the basics.

About Shore Power

When you eavesdrop on seasoned RVers talking about their rig’s electrical systems, you’ll probably hear the words shore power from time to time. This is the term used to refer to the power supply at a campground or parking area. Each shore power station is typically located next to a group of campsites—or even a single site.

Look for the circuit breaker on the shore power system. You’ll need to turn it on after connecting your rig to the system. Don’t forget to turn it off again when you leave in order to conserve energy.

A Word About RV Extension Cords

Regular extension cords are not suitable for RV use. They might look sturdy enough, and the plugs might even fit your adapter, but they’re not equipped to carry the amount of amperage you’ll need. In fact, they pose a significant fire hazard.

Moreover, some RV power cords are equipped with locking rings that help to stabilize the connection while protecting the plug from the elements. If you want to power your appliances while staying safe, you’ll need a power cord designed specifically for RVs.

Understanding RV Adapters

Because some campgrounds might offer only a 30A or 50A hookup, you should keep an adapter handy so you won’t find yourself stuck without power.

There are two types of adapter for RV extension cords: dogbone and puck adapters. Both are designed to alter the shape of the plug on the shore power source. They don’t actually change the power output—the alteration is purely aesthetic.

Dogbone adapters are versatile and generally safer on account of their design. High-end models, like the Camco units we’ve listed above, will usually come equipped with handles to protect against shock.

Puck adapters, on the other hand, are more convenient due to their smaller size, but they might get dangerously hot. The connection they offer isn’t quite as secure, either, which is why we prefer dogbone adapters if you have the space to store them.

About Corrosion

If you have an RV power cord, be careful not to let rust build up on the prongs. This will make the plug more resistant when entering the outlet. It also causes the metal to heat up more quickly, which might damage the RV’s electrical system.

Use a wire brush to clean the prongs on your power cord regularly. Make sure both ends are unplugged before touching the metal, and use a gentle touch to avoid warping.

In Conclusion

Why do we feel that the Camco 25′ PowerGrip Heavy-Duty model is the best RV power cord?

First of all, it’s exceptionally durable, with a strong sheath that can hold up to frequent use. The copper wiring allows for a reliable connection, and the cord is available at a decent price. Our one complaint is that the length could be more generous, but it offers plenty of bang for your buck nonetheless.

Best of luck, and happy camping!
