Query: Be Careful!

This heater lasted about 10 seconds in my car. I have a 2001 Toyota Corolla and I didnt have the stereo on or anything and I plugged in this heater and it blew my fuse. My cigarette lighter uses a 15amp fuse and it is a 12v socket which only has a maximum wattage output of 180 watts (12 x 15) so please make sure your car has enough power to use this heater. Honestly if it blew a fuse that quick, its not meant for the everyday car so buy at your own risk. Plus I had to pay to return the darn thing so that was $5 in the trash
