PAULINN 15 Amp 125V AC Power Inlet Port Plug W/Integrated Dual 18 Extension Cord, NEMA 5-15 RV Flanged Inlet Y Splitter Cable with Waterproof & Back Cover, 2 Pole 3-Wire Shore Power Plug for Boat

Now I have power to my outbuilding.

I used this to connect a block heater and on board trickle charger.

Ill be Back !

Great product and super easy to install. My only issue is the cap doesnt stay in. I first installed it upside down so the flap would fall out because of gravity. Simple matter to reinstall it - but still the flap falls out.

Works as expected. Good value for the price.

Exactly what Ive been looking for. Attaches using 4 screws rather than 3 like their competitors. The heavy duty wiring is perfect for my needs. Installed in a car hauler.
