The problem with this gadget when you use on the ordinary cigarette lighter adapters... it has a low wattages rating... your wire must accomodate around 120 watts for this.. if not you have busted fuse the worst thing is your electrical will be caught on fire.. some vehicle right now has to two cigarette lighter adapters for the low wattage use (the normal one) and the other is the high wattage for this gadget..
