I purchased an off the shelf inverter from the internet 450 watt. ( about 30 dollars ) The unit draws too much power to use the cigarette lighter outlet up near the TV
I built my own receptacle box to plug it into ( cigarette lighter type ) which I installed in the floor to the right of the steps into the unit ( its out of the way there ) (pepboys and home depot about 15 dollars). I ran two wires off the battery ( neg and positive ) to the receptacle with an inline fuse. When I need to power the TV I plug the inverter into receptacle on the floor and run and extension chord to the TV.
