Abstract
Disclosed is a power inverter for use in converting 12VDC to 115VAC, the power inverter is adapted for securement to a conventional trailer hitch connector. The power inverter provides remote power to 115 volt accessory items by use of a conventional 115 volt output receptacle positionable at the rear of a vehicle by use of the trailer hitch connector so as to eliminate the need for extension cords commonly used when powering 115 volt accessories from a conventional vehicle.
