Choosing the right RV extension cord is essential for convenience, safety and reliable power. When you choose a durable extension cord based on your RV’s amperage and the distance you need it to reach, you can enjoy your camping lights, devices and appliances without interruption.
Can You Plug Your RV Into an Extension Cord Safely?
Extension cords make it easier to connect external appliances, such as air fryers, to the campsite’s power source. As long as you use the correct type, you can safely connect an extension cord to your RV.
Can You Use a Regular Extension Cord for Your RV?
RVs require special extension cords rated for the amount of amperage that moves from a campground’s electric hookup to your camper. Rather than using a standard outdoor or household extension cord, you will need a 30- or 50-amp cord to prevent overheating, melting and potential fire.
When you plug an RV extension cord in properly, it can carry the power your RV needs so you can enjoy the conveniences of home and the beauty of the great outdoors.
How to Choose an RV Extension Cord
You can choose the best RV extension cord when you know what to look for. Consider the following factors before investing in an extension cord for your next camping adventure.
Durability
The best RV extension cord brands manufacture durable, long-lasting cords. Investing in a heavy-duty cord helps ensure you get the most years out of it before needing a replacement.
Weather Resistance
A cord’s weather resistance is also essential. You should always use a cord made with heavy-duty rubber or polyvinyl chloride (PVC) because these materials protect your cord from ultraviolet rays, wear and tear, and moisture.
Amperage
Choosing an extension cord with the right amperage depends on your RV’s amperage. The electrical panel’s display should indicate whether it is 30 or 50 amps, but you can also tell by the outlets. A 30-amp RV outlet fits a three-prong plug, and a 50-amp outlet fits a four-prong plug.
Gauge
An RV extension cord’s gauge is also important because it indicates how thick the cord’s wires are inside the cable. A lower gauge number means the cord’s wires inside the cable are thicker and can carry more amps than cords with higher gauges.
Length
RV extension cords typically come in 15-foot, 25-foot, 30-foot, 50-foot, 75-foot and 100-foot sizes. While you want your RV extension cord to reach your campsite’s power source, choosing the shortest cord possible enables it to deliver an adequate amount of electricity to your RV. Extra-long cords contain thicker wires to transfer power, and they can increase electrical resistance. Remember — resistance causes electrical energy to turn into heat, and heat increases the chances of an electrical fire.
The ideal extension cord is long enough to connect your camper to its power source but not so long that it leaves an excessive amount of extra cord length. It is usually best to stick with cord sizes between 15 and 30 feet.
Using a shorter cord reduces tripping hazards on your campsite and prevents voltage drops that could potentially damage your RV. Most campgrounds provide sites with convenient, easy-to-reach power sources, so you should do well with a short or medium-length cord.

RV Extension Cord Safety Tips
Extension cords are safe to use with your RV if you use the right cord correctly. Remember the following safety tips when connecting your RV to power.
Use a Surge Protector
You should use a surge protector each time you plug your RV into a power source. The surge protector goes between your extension cord and the power pedestal, and it absorbs excess voltage to prevent power surges from damaging your RV. Surge protectors are especially important during storms because they protect your RV, appliances and devices from powerful surges caused by lightning strikes.
Some cords feature built-in surge protection and additional safety features, such as power indicator lights and overload protection.
Keep Your Extension Cord Away From Water
Keeping your extension cord as dry as possible prevents short circuits, electric shock and potential fires. While a little rainfall is okay, try to keep your extension cord off the ground in the event of heavy rain or snow. The plug’s prongs should be dry and protected from moisture at all times.
Ensure the Cord Is Uncovered and Visible
It is common to see campers covering their extension cord with decorative rugs to prevent tripping, but covering your cord presents potential fire hazards because rugs can trap heat. Rather than placing a rug over your cord, keep it visible and away from foot traffic to prevent your friends and family members from tripping over it.
Avoid Pulling the Cord
Unplugging your extension cord by pulling on the cord instead of the plug can damage its interior wires. Ensure you always pull it from the plug to maintain a safe electrical connection.
