stio 15 Amp AC Port Plug, 125 Volt AC Power Inlet Socket with 16 Inch Extension Cord and Watertight Cap, Waterproof Integrated Outdoor Electrical Outlet Receptacle Box for RV,Boat,Pickup,Jeep,Truck

I shopped for some time before purchasing this product. The selling point is 12-gauge wire. Just installed, not clear about lifespan, but the features are as represented. I am using this for a 750W/120V engine block heater. I wanted a safety margin.

This Power Port is a great idea for many different tasks when you need to have power going through a wall without having an open hole when not in use. For me it is the outside plug for “shore power” on a Tear Drop camper Im building.

I installed this on my boat on the outside of my center console. Now I can plug in my 3 bank charger without going into the console to get the plug. The installation screws are not stainless, as my boat is a saltwater boat, I had to trade them out for stainless. Not that big of a deal, but be aware they are not stainless screws. I put them through the magnet test.

Added to ocean boat for a clean install.
