    Was really easy to hook up, the ONLY downside is the wires are short and you will need to modify/make new ones if you want to hardwire it into your vehicle.

    It works pretty good. I bought it for grandson to plug his Xbox up and his small tv. It has two different ways to supply power to it. If use both plugs at the same time and you are using the cigarette lighter adapter you will higher voltage cigarette light plug. You can also hard wire to battery and mount it somewhere in well ventilated place in vehicle.
