Review on ⚡️ Kohree 15A Flanged Inlet 125V, NEMA 5-15 Flanged RV Shore Power Inlet Receptacle Generator AC Port Electric Plug for Marine Boat RV Electrical Connections - Waterproof Cover, 2 Pole 3-Wire by Jim Shirodkar

Excellent product. So I bought this for a trailer I was building a country trailer. I use Yeti 400 Battery Target Zero with solar panels. But when I'm not using the trailer I want to be able to keep the battery charged. It is permanently installed in the trailer. So instead of stretching the line and leaving one of the hatches open. I installed it. I extended the extension cord that I had cut off and plugged it straight into the back of this unit. The plugs connect directly to the charging plug that charges the gold zero. Make sure you have the correct hole saw size, inch and 7/8. It's waterproof. There are two screws, they are scrap. I used the stainless steel screws I had and just painted them black. I added some silicone during installation. Waterproof guarantee. The cork is a rubber stopper. If it is tight and attached to the ring during assembly. It's definitely a nice extra feature. Also, if I ever camp at a regular campsite, I can just plug into a power source.
