EV Charging Gear for RV Camping

What We Pack

Charging an EV at a campground comes down to a handful of cables and adapters. None of it is exotic, but the details matter, and the wrong cord or the wrong adapter is the difference between a quiet overnight charge and a scorched plug. This is the gear that lives in our electrical bay and why each piece is there.

Everything below covers the connection between the campground pedestal and your charging equipment. For which adapters match which car and connector, our adapter guide goes deeper.

• A 50-amp extension cord, for when the pedestal is parked across the site from your EVSE.
• A 120-volt 12-gauge extension cord, for slower charging off a standard outlet.
• A weatherproof cover, to keep the 120-volt connection out of the rain.
• The TT-30 charging adapter we leave on the shelf, and why.
• A pair of dogbone adapters, for powering the trailer when your EV has the 50-amp outlet.

A Few Words Before You Buy

We are EV camping enthusiasts, not licensed electricians. Everything here comes from our own miles and the wider community, not from a trade certification. Treat it as experience shared, not professional electrical advice, and use any of this gear at your own risk.

Campground power is only as good as the pedestal it comes from, and pedestals vary wildly in age and condition. So we plug in, and then we pay attention. Keep an eye on your gear while it is in use, check that plugs and adapters are not running hot, and do not walk away from a connection you are not sure about. If a camp host points you to a particular outlet or asks you not to charge, listen to them.

If you are ever unsure about an outlet, the wiring at a site, or your own setup, ask a qualified electrician. The cost of asking is nothing next to the cost of getting it wrong.

The 50-Amp Extension Cord

The 14-50 outlet you want is rarely where you want it. Pedestals end up behind the trailer, across the pad, or just far enough that your EVSE cable comes up a few feet short. A proper 50-amp RV extension cord closes that gap without choking the current.

When the reach is a question mark, the Camco PowerGrip 30-foot 50-amp cord buys you margin. One honest warning: a 30-foot 50-amp cord is heavy, genuinely heavy, and a chore to coil and stow. Buy the shortest length you think could actually work for your setup rather than reaching for the longest one by default.

Whatever cord you settle on, buy it from a reputable brand and read the reviews before you commit. This is not the place to cheap out. A bargain cord under a sustained charging load is exactly the kind of connection you do not want running while you sleep.

The 120-Volt Cord for Slow Charging

Some parks only let you charge on a standard household outlet and will not let you plug into the 50-amp. Or maybe the 50-amp is spoken for because your trailer needs it. Either way, you are pulling a continuous 12 amps or so for hours, and that is hard on a flimsy cord.

We keep a 12-gauge outdoor extension cord for this. Twelve-gauge copper handles the long, steady draw with less voltage drop and less heat than the lighter 16-gauge cords sold for lamps and leaf blowers. It is slow charging, no way around that, but slow and steady overnight is how a lot of campground charging actually gets done.

A Weatherproof Cover for the 120-Volt Outlet

Rain and an open, energized connection are a bad pairing. When you are charging off an exposed 120-volt outlet, a weatherproof in-use cover keeps water off the plug while the cord stays connected.

It is a small, cheap piece of gear that you will be glad to have the first time a storm rolls through at 2 AM. If the connection is going to sit outside for hours, give it a roof.

The Adapter We Do Not Recommend

You will see the Parkworld TT-30 to 14-50 adapter sold as the key to charging at every older 30-amp campground. We do not recommend it, and we explain the full reasoning in our outlet guide.

The short version: this adapter presents your EVSE with a 14-50 receptacle, so your car believes it is on a 240-volt, 50-amp circuit when it is really on a 120-volt, 30-amp one. You can dial your charge rate down by hand, but many EVs snap back to a higher default after any power interruption, and campground power blinks all the time. Pull 32 amps through a 30-amp circuit overnight and you are overloading the adapter, the outlet, and the wiring behind it.

We list it here because we know you are going to wonder about it, and you will see it recommended everywhere. That is not the same as us recommending it. If you insist on using one anyway, never let it exceed its rated amperage. Set your car to 24 amps every single time you plug in, watch it, and understand that a melted plug is the failure mode you are gambling against.

Powering the Trailer When the EV Has the 50-Amp

Here is a problem unique to towing an EV-charging setup: your car is plugged into the pedestal 14-50, and now the trailer has nowhere to go. You have two ways to split it.

The simplest is to leave the trailer where it belongs, on the 50-amp outlet, and charge the car off the standard 120-volt household outlet instead, using the 12-gauge extension cord from earlier. It is slow Level 1 charging, but if you are settling in for a few days, it will likely still top you off over the course of your stay while the trailer keeps full power.

The other way is to keep the car on the 14-50 and run the trailer off a separate household 15-amp outlet with a dogbone adapter, using the standard 5-15 plug you find on most pedestals and around the property. Which dogbone you need depends on your trailer cord. Match the female end to your shore cord:

The Bottom Line

Camping with an EV still puts you out on the frontier a little, working out things most campers never have to think about. The good part is that the kit which smooths it over is short and friendly: a heavy 50-amp cord to reach the pedestal, a 12-gauge cord for slow nights, a cover for the rain, a couple of dogbones for the trailer, and the discipline to skip the adapter that wants to overload a 30-amp circuit. Pack that, watch your connections, and the charging part of EV camping mostly takes care of itself.

When you know where you are headed, check the park first. We track EV charging policies for over 500 RV parks, because the best gear in the world does not help at a campground that will fine you for plugging in.
