Question:

Not sure what term to search but looking for something that will power up 7-way tongue jack using battery or 110v regular 3 or 2 pin connector. Basically looking to power up a parked trailer using external battery or power bank with regular 3 or 2 pin plug What all would I need and is this possible?

It sounds like you want to power your trailer jack using a 110V AC wall outlet. I do not have a way a to plug the whole 7-way into a wall outlet. There are two ways you can power the jack with an external battery powered with AC power.

The first way is the most permanent solution with a converter. Wire the external trailer battery to the jack and then wire the battery to a converter like Progressive Dynamics Inteli-Power Converter and battery charger part # PD9130LV. You want to wire the converter to an external trailer battery. The other side of the converter wires to a 30 amp inlet on the trailer part # 277-000138. You'll need to cut the plug off of the wire that's coming from the converter. The power cord part # A10-3025ED90 plugs into the inlet to an adapter part # A10-1530HVP that fits into the 110 wall outlet. Wiring the inlet is the best and most convenient way to power the jack with AC power in the long rung because you simply plug into the inlet to charge the battery that is powering the jack.

If you want a less permanent but easier to install option you can wire the lights to a trailer battery and charge it with a universal battery charger part # CTEK56674 with AC power from the 110 outlet. The CTEK charger does have to be attached to the trailer battery each time you want to charge it which can become inconvenient.
