Aims Power 4000W Charger/Inverter Need 120V power in your truck, RV, or any other project? I've got what you need. I don't have a 12V battery, so I haven't tested it, but it worked when I took it apart. The little "CHARGE CURRENT CONTROL" dial on top is broken (I don't know if it's repairable). The small LCD screen shows the battery level. The screen alone is worth more than the minimum bid. I can provide you with the wire that connects the screen and the inverter. Model: PICOGLF40W12V120V
