DO NOT buy this product. I read the directions, and this still did not charge my car or truck. I tried calling the number on the bottom of the Mighty Jump Pro, and after being on hold for 10 minutes, a message came on and said leave a message and then said sorry there is a problem the mailbox is full. I am a woman and bought this.
HSN should check their products more thoroughly before putting on air. A waste of my money and no support system. I will not be buying any more products from HSN.
Bottom Line: No, I would not recommend this to a friend
