Camco 55135 PowerGrip 50A Male to 30A Female Adapter

Here's the situation this little adapter solves. You roll into a campground or hook up to a friend's power station, and the only outlet you've got is a 50-amp receptacle. Your rig runs a 30-amp shore cord. Without an adapter, you're stuck. The Camco PowerGrip 55135 bridges that gap so you can plug a 30-amp RV cord straight into a 50-amp power source and get camp set up.

Let's be clear about which end goes where, because that trips people up. The 50-amp male end plugs into the 50-amp outlet at the pedestal or power station. The 30-amp female end accepts the male plug on your RV's shore cord. So your 30-amp camper talks to a 50-amp receptacle through this one piece. It's the go-to when the site was wired for a bigger rig than yours.

The offset body is the smart part. Instead of a straight inline plug that dangles and tugs, the offset style angles the connection and takes strain off the receptacle. That means less wobble at the outlet, less arcing over time, and a connection that stays seated. Camco also molded a PowerGrip handle right into the housing, so grabbing and pulling the plug is easy even when it's a snug fit. Anyone who's fought a stiff shore-power connection in the dark knows why that handle matters.

One thing we want to be straight with you about. This adapter doesn't turn your 30-amp RV into a 50-amp RV. It's a physical connector, not a converter. Your camper still draws the same 30-amp, 120-volt service it always has, and its onboard breakers still protect it the same way. What you're buying is the ability to connect, nothing more and nothing less. And that's exactly what you want. No mystery electronics, just a solid pass-through. A 30-amp RV service tops out around 3,600 watts at 120 volts, and that ceiling stays right where it is whether you plug into a 30-amp outlet or a 50-amp one through this adapter.

A couple of honest notes on the design. It's a non-locking adapter, so the connection isn't a twist-lock, it seats and holds by friction and the weight of the offset body. For most driveway and campground use that's fine, but if you're in a spot with a lot of movement on the cord, route it so nothing's yanking on the plug. It's also not waterproof. Keep the connection up off wet ground and out of standing water, same as you would with any shore-power plug. A little common sense here goes a long way toward a safe, trouble-free hookup.

This adapter also earns its keep beyond the campground. Plenty of folks use it to connect a 30-amp rig to a portable power station or a generator that's built with a 50-amp outlet, and it works the same way there. Plug the 50-amp male end into the source, run your 30-amp cord into the female end, and you're powered up. It's a common setup for boondockers who carry a big inverter or generator but rig their trailer for 30-amp shore power.

Who needs one? Anybody running a 30-amp trailer, van, or small motorhome who wants the flexibility to plug in at 50-amp sites, at a buddy's place with a 50-amp outlet, or at a power station that only offers the bigger receptacle. It's the kind of adapter you toss in the electrical bay and forget about until the day you really need it. And on that day, you'll be glad it's there. If you want to protect what's downstream, we'd pair it with a Camco surge protector on the same cord run so bad park power never reaches your coach. We'd keep one on board year-round.
