Camco 55522 PowerGrip 30A 90-Degree Locking Adapter
Camco 55522 PowerGrip 30A 90-Degree Locking Adapter — Product description
The Camco 55522 PowerGrip is the short 90-degree adapter that ties a marine-style 30-amp RV or boat power inlet into a standard 30-amp shore source. Locking female connector, molded plug-head handle, and a fully waterproof body. It's the little piece that makes a clean, strain-free dockside connection instead of a dangling, wet mess.
The Camco 55522 is one of those small parts that quietly fixes a real headache at the dock. If your boat or RV has a marine-style power inlet, the kind with a round twist-lock face, you can't just plug a standard 30-amp cord straight into it. This 90-degree PowerGrip adapter is the bridge. One end is a locking 30-amp female that mates to your marine-style inlet, the other is a standard 30-amp male that drops into any regular 30-amp shore source. Eighteen inches, waterproof, done.
The 90-degree bend is the whole point. A straight plug sticks out from the hull or the RV side wall and takes every bump, every dock line, every coil of the cord as strain right at the connection. The right-angle body turns the cord downward so it runs flat and tidy against the boat. That keeps the weight off the pins and the locking collar, which is exactly where these connections tend to fail when they're left to dangle season after season.
Camco molded a plug-head handle into the body, and it earns its keep more than you'd think. Shore power connectors are stiff, and a cold, wet twist-lock can fight you. Having a real handle to grab means you can seat and lock the connector one-handed, leaning off a swim platform or reaching into a transom locker, without wrestling the cord itself. It's a small thing that you notice every single time you hook up.
The body is fully waterproof, which matters because this connection lives outside in spray, rain, and dock splash. The locking female end twist-locks to the inlet so it won't back out with wave action or vibration, and the seal keeps water out of the pins. On a boat that sits in a slip all season, that's the difference between a connection you trust and one you're always checking.
Where does it fit? Think transom lockers on center consoles and cruisers, side-wall inlets on RVs and vans, and any rig running a marine-style 30-amp inlet off a dockside pedestal or a standard 30-amp outlet. Because it's only 18 inches, treat it as an adapter pigtail rather than a run of cord. If your pedestal is any distance from the inlet, you'll pair this with a proper 30-amp shore cord and let the adapter do the connecting right at the boat end.
It's a favorite for seasonal boaters and full-time RVers alike because it takes the guesswork out of an odd connection. New owners run into the marine-style inlet and assume they need some special cord, then spend an afternoon at the parts counter. You don't. This is the adapter, it's rated for the job, and it goes on in seconds. Keep one in the shore-power bag and you'll always be able to plug in, whether you're at your home slip or a strange pedestal three states away.
A word on amperage, because it's worth being straight about. This is a 30-amp adapter. It'll tie a marine-style 30 or 50-amp inlet to a standard 30-amp source, but it delivers 30 amps, not more. If your inlet and onboard panel are 50-amp, you're limited to 30 amps of draw through this piece, so size your load accordingly and don't try to pull a full 50-amp service through a 30-amp connection. Match your amps and everything stays cool.
One maintenance tip from folks who leave these connected in salt or brackish water: hit the locking collar with a little dielectric grease a couple times a season. The threads can bind up over time if they're left dry, and a dab of grease keeps the lock turning smoothly and helps seal out corrosion. Do that and this adapter will outlast a lot of the gear around it. It's simple, honest hardware that solves a specific problem, and it's the part we reach for when a customer needs to get a marine-style inlet talking to standard shore power.

Frequently asked questions
What does the Camco 55522 actually connect?
It bridges a marine-style RV or boat power inlet to a standard 30-amp shore source. One end is a locking 30-amp female that mates to your marine-style inlet, the other is a standard 30-amp male that plugs into a regular 30-amp outlet or pedestal.
Why is the connector bent 90 degrees?
The right-angle body turns the cord downward so it runs flat against the hull or RV wall instead of sticking straight out. That keeps dock lines, bumps, and the weight of the cord from straining the pins and locking collar, which is where these connections usually fail.
Is it waterproof?
Yes. The body is fully waterproof and the locking female end seals against the inlet, so it holds up to spray, rain, and dock splash. That's important because this connection lives outside all season.
How long is it?
18 inches. It's meant as a short adapter pigtail that connects right at the boat or RV, not as an extension cord. If your pedestal is any distance away, pair it with a proper 30-amp shore cord.
What's the plug-head handle for?
It gives you a real grip to seat and lock the connector one-handed. Shore power twist-locks are stiff, and the handle lets you push and turn without wrestling the cord itself, handy when you're leaning off a swim platform or reaching into a transom locker.
Does the connector lock so it can't come loose?
Yes. The 30-amp female end twist-locks to the marine-style inlet so it won't back out from wave action, vibration, or someone tripping the cord.
Can I use this to run my rig from a standard household outlet?
No. This is a 30-amp to 30-amp adapter and needs a real 30-amp source like an RV pedestal or a 30-amp shore outlet. It is not a step-down to a household 15 or 20-amp receptacle.
My inlet is 50-amp. Can I still use this?
You can connect it, but it delivers 30 amps, not 50. If your onboard system is 50-amp you'll be limited to 30 amps of draw through this adapter, so keep your total load under 30 amps and don't try to pull a full 50-amp service through it.
Is this for boats or RVs?
Both. It's designed for the marine-style twist-lock power inlets found on boats, RVs, and vans, connecting them to standard 30-amp shore power.
Any maintenance tips if I leave it connected all season?
If you keep it plugged in around salt or brackish water, put a little dielectric grease on the locking collar a couple times a season. It keeps the threads from binding and helps seal out corrosion so the lock keeps turning smoothly.
