I have a 400 watt power inverter that came with a cigarette style plug and a clamp on positive/negative hook up but that was not strong enough to run my 32" LCD t.v.. So, I went and bought an 800 watt converter for the t.v. and it powers it just fine, however it only came with battery clamps, no cigarette plug. Is it okay to run the 800 watt'er off of a cigarette plug or will I fry the trucks wiring? Please advise, going tailgating in AM and don't want to run extension cords if I don't have to. Thanks everyone.
