Camco 55562 50 Amp 90-Degree PowerGrip RV Adapter

If you run a marine-style twist-lock power inlet on your boat or RV and you keep fighting a shore power connection that doesn't want to line up, this Camco PowerGrip adapter is the fix. It's an 18-inch dogbone that puts a 50-amp locking female connector on one end and a standard 50-amp male plug on the other, with a 90-degree bend built into the female side. You plug the standard male into the shore pedestal or a standard 50-amp power source, and the locking female mates to your marine-style 30 or 50 amp inlet. Simple, and it solves a real problem.

The 90-degree elbow is the whole point here. A straight plug hanging off a low-mounted inlet pulls down on the cord and puts a slow, steady strain on the connector pins. Over a season that strain is what kills plugs. The right-angle bend routes the cord flat against the hull or the RV sidewall so the weight of the cable isn't hanging on the contacts. It also tucks into tight lazarette and inlet spaces where a straight connector simply won't clear.

There's a molded plug head handle on the connector, and it earns its keep. Plugging in one-handed on a pitching dock, in the dark, with your other hand on a rail, is a lot easier when you've got something solid to grip and push. The threaded locking ring on the female end screws down over your inlet so the connection can't vibrate or rock loose, and the whole assembly is built to shed weather so rain and spray stay out of the contacts.

A few install notes from people who've lived with these. First, give the connector a light coat of dielectric grease on the pins before you first mate it. Saltwater air is hard on any locking collar, and the grease keeps corrosion from creeping in and keeps the ring turning freely months down the road. Second, once you've routed the cord the way you want it, snug a cable tie around the elbow so the 90-degree bend can't slowly rotate. If it rotates it wears on the O-ring seal, and a worn seal is how moisture finds the pins. Small steps, big payoff in reliability.

One thing to be clear about: this is an adapter, not an extension. It's 18 inches long. If your inlet sits at the transom and your pedestal is 20 feet away, you still need a proper 50-amp shore cord to make up the distance. This just gives you the right-angle, locking transition at the boat or RV end. And match your amperage. A 50-amp connection wants a 50-amp source and cord end to end. Don't try to feed a 50-amp system through a smaller service without the correct step-down adapter, or you'll run hot.

Who's this for? Boaters and RV owners with a marine-style twist-lock inlet who want a cleaner, better-protected shore connection. Trawler and cruiser owners with the inlet buried in a tight lazarette love the 90-degree clearance. If you've been babying a tired straight plug through another season, this is a cheap, sensible upgrade that'll outlast the connector it replaces.

Camco has been building RV and marine electrical gear since 1966, and their PowerGrip line is the stuff you see on docks and in campgrounds everywhere for a reason. It's straightforward, it holds up, and it's priced so you're not afraid to keep a spare in the electrical locker. The connectors follow the standard 50-amp marine-style twist-lock pattern, so it drops right onto the inlets already on most modern boats and larger RVs. No rewiring, no adapters stacked on adapters. Pull the old connector, thread this one on, and you're done.
