RV Extension Cord – 2022 Buyer’s Guide

Getting the right RV extension cord is essential to having fun on your camping trip. Plugging in allows you to use all your RV’s amenities without having to worry about battery power. You want to make sure that you have a cord that can both deliver the power you need and last for a long time. 

What to Look For in an RV Extension Cord 

The best RV extension cord will handle the elements and deal with the rigors of travel. They also have to fit your RV and deliver enough power so that you don’t have to worry about being able to use everything your camper has to offer. 

Current 

Each camper will have a current that they can handle. You will see 30 amp and 50 amp RVs. If you don’t know which one you have, you can look at your plug. Three prongs indicate you have a 30 amp RV. If there are four prongs, you have a 50 amp RV. 

Most smaller RVs have 30 amp plugs. They run one air conditioner and small RV-sized appliances. They also usually have only one tv. 

Larger RVs that use multiple air conditioners, full-sized appliances, and multiple TVs need the bigger 50 amp option. 

Gauge 

Gauge is the diameter measurement of the conductive material in the wire. The lower the number, the thicker the wire, meaning a gauge of 0 would be the biggest conductive wire. Most of the 30 amp cords are ten gauge. Most of the 50 amp cords are eight gauge. 

Many cords can look thick because of how much insulation they use, but the gauge rating will tell you the size of the cord. Lower gauge numbers will allow extension cords to go further without having issues. 

Length 

There are many options in length when buying extension cords. Most prospects will come in standard 25, 50, and 100ft RV extension cord lengths. The longer the cord, the lower you will want the gauge. 

50 amp cords tend to be shorter than 30 amp cords because adding length to the higher power option usually involves a big jump in price. If you need an extra-long cord, don’t worry. They exist, but you might have to pay a premium for them. 

Weatherproofing 

Your RVs extension cord is going to be outside. You want to make sure that the insulation and weatherproofing are tough enough to handle the conditions you are likely to encounter. Cold weather can be a significant issue if you are taking your RV north in the winter. 

Finding an extension cord that can handle more weather than you plan on encountering is ideal. Depending on your location, this might mean extreme heat or cold. You will also want to make sure it is UV light and waterproof. 

Best 30 Amp RV Extension Cords

A 30 amp RV extension cord is the usual option for smaller campers and RVs. They are perfect for running smaller appliances and a single air conditioner unit. These cords tend to have higher gauges, which means their cords are thinner and easier to store. 

One perk to a 30 amp RV is that if you keep a 50 amp adapter, you can always use all your equipment no matter what plug is available.

Adapter Options for 50 and 30 Amp Extension Cords

If you don’t know what options might be available at your campsite, or you want to prepare for any situation, you can get adapters that let either extension cord plug into both inputs. However, here’s the problem, the adapters lower all the power down to 30 amps. 

A 30 amp adapter for a 50 amp plug limits the current to the 30 amps level. Of course, a 30 amp plug only gives the lower current, so it automatically limits the amount of power you can pull. It allows you to connect, but you may not be able to use all your RV’s tools. 

Having adapters does give you more choices, and it helps you keep your RV running, even when you are in an unexpected situation. They are great to add to your extension cord storage, just in case.
