I got a HummerTM made by GM as a father's day gift and its yellow. Its really a HummerTM Portable Power Center with Inverter and yes it really is made by GM. It has an 18-AmpHour battery with 2 x 110V sockets and 2 x 12V sockets as well as a work light and air compressor. Now I have an electric Hummer in the back of my Prius. :lol:
