Query: Warning-do not use with cigarette lighter

I bought this because my blower fan went out and I needed some source of heat in my car until I could get it repaired. This unit has a heating element that is very small yet it still manages to frequently blow fuses. Well I found out why. A tag on the cord says "Do not plug it into the vehicle cigarette lighter. " Well, where else is it supposed to be plugged into with its 'cigarette lighter looking' plug? I have a socket in the cargo area of my Passat but then how can the heater warm me in the front seat and defrost my windshield? I am returning it after 3 blown fuses. My curling iron throws off more heat than this... I wonder if I can plug THAT in to my vehicle cigarette lighter...
