How to Power Electric Trailer Jack When Vehicle With 7-Way Isnt Available
Question:
I just ordered a Electric Jack w/ Footplate and 7-Way Plug - A-Frame - 25-1/8inch Lift - 3.5K - Black and while I realize there is a manual raise/lower option is there a way to run this when a vehicle with hot 7 pin connector is not available? Is there an adapter for 7 pin socket to 12v or 110v so I could plug it into household power or tap into trailer battery?

To run the jack using 110V shore power, you'll need a bench-top type 12-volt power supply which you can easily find online. You'd also need a 7-way socket and pigtail like # 20024. If you choose a power supply with screw terminals on the front of it, the black pigtail wire would connect to the positive terminal and the white pigtail wire to the negative terminal on the power supply. You'll want to use a power supply capable of putting out at least 30A.
To run the jack off the trailer mounted battery, you could use the same # 20024 7-way/pigtail. The black wire on the pigtail would attach to the positive battery terminal and the while pigtail wire would connect to either the trailer frame via a frame ground or directly to the negative battery terminal.
Once this is rigged up, you'll be able to easily power your jack via shore power or the trailer mounted battery.
