It has a 12v input on it, and it will work off the car battery directly when the car is not running, but when the car is started and charging it shuts down. The inverter they have been using to power it thru the mains input has blown up when a PS3 was tried on it, and I thought a laptop power in the car adapter with a 12v output would do the trick to get the TV working again. The thing is do they actually regulate down as well when charging? They are not that expensive to get off trademe but I dont want to suggest it and have the same thing happen.
I want to get my inverter back off them ;)
