I have 3 power inverters pulled from ambulances. One is a Vanner 20-1000tul, one is a Vanner 20-1050cul, and the other one is a Tripplite EMS1250ul. They are 1000w, 1050w, and 1250w respectively. All of them can be connected to shore power and charge the batteries they are connected to. They are Inverter/chargers. I will attach pictures. 500$ each and I can ship for 20$ to the lower 48 states.
