Camco 55338 Power Grip 30 Amp Generator Adapter

If you've ever pulled into a quiet boondocking spot, fired up the generator, and then realized your RV cord won't plug into it, you know how that goes. The Camco Power Grip Generator Adapter, part number 55338, is the little piece that fixes it. It bridges a generator's 4-prong locking outlet to the standard 30-amp plug on your RV's shore power cord. Plug it in and you're running your rig off generator power in about ten seconds.

Here's how it works. One end is a NEMA L14-30P male plug. That's the 4-prong twist-lock connector you'll find on a lot of portable and standby generators rated for 30 amps. It twists into the generator's outlet and locks, so a bump or a tug on the cord won't pop it loose. The other end is a NEMA TT-30R female connector, which is the exact receptacle your RV's 30-amp power cord expects. Your existing cord plugs right in, the same way it would at a campground pedestal. If your generator has that 4-prong twist-lock outlet, this is the piece that connects the two worlds. Nothing to rewire, nothing to assemble.

The adapter is rated for 30 amps at 125 volts, which comes out to 3,750 watts of pass-through power. That's enough to run the essentials in most 30-amp rigs, your air conditioner, converter, fridge, and outlets, as long as the generator itself can keep up. Just remember the adapter passes power through, it doesn't create it, so a small inverter generator will still only give you what it's rated for. Camco builds the internal terminals from brass, which carries the current cleanly and holds up against corrosion far better than the thin stamped contacts you find in bargain adapters. On a part that's passing 30 amps, that matters.

The Power Grip name comes from the contoured body and the non-slip grooves molded into the housing. Sounds like a small thing until you're plugging and unplugging in the dark, in the rain, or with cold hands at the end of a long drive. You get a real grip on the body instead of yanking on the cord, and pulling on the cord is exactly how connectors get wrecked. There's no separate handle on the plug head, the grip is built right into the shape of it.

It's ETL listed, so it's been tested to recognized electrical safety standards, not just thrown together. A few things to keep in mind so you use it right. Run it only on a 30-amp, 125-volt circuit protected by the correct breaker. It's built for RV power specifically, so don't press it into service as a general adapter for other gear or stack it with other adapters. And it isn't waterproof. Keep the connection up out of standing water and don't leave it sitting exposed to the weather any longer than you need to. Treat it like you would any other live electrical connection at the campsite.

Size-wise it's tiny. Camco lists it at 2 3/4 inches long, 2 inches wide, and 2 1/2 inches tall, and it weighs about 0.41 pounds. It disappears into a cord bag, a storage bay, or the same tote that holds the rest of your camp power gear. Toss one in before a trip and you're covered whether you end up on shore power or running the generator that night.

Who's it for? Anybody who camps off a generator. Weekend boondockers, tailgaters, folks keeping the RV livable during a power outage at home, or anyone who just wants a clean, safe way to feed generator power into a 30-amp rig. It's about as plug-and-play as gear gets. No tools, no wiring diagram, no trip to the hardware store. Keep one with your cords and you'll never be the person standing at the generator wondering why nothing lines up.
