OMG have you guys seen this thing. It does everything but call your wife up and tell her your going to be late. Un-believeable amount of stuff it does, Jump start your car and it won't let you hook it up backward by accident and tells you how many volts your battery is producing, blows up the tires, you just set the pressure you want and walk away and it shuts off when it reaches the correct pressure, you can plug your laptop into it, it has two standard outlet that you can handle 500 watts apiece. It will charge your cell phone. QVC has it on special today.
