Ahhhh that makes more sense. We tried a heat exchanger one as well and burnt it out in about 2 hours. I have one of the heat exchanger type coolers that you plug into your car and it actually works pretty well as long as the car is running. Will suck a battery dry in about and hour if it isn't though.
