Query: Warning!!! Fire Hazard!!!

I bought this product strictly as a holder/charger since my truck has an auxiliary jack for MP3 players. After about 2 minutes of it plugged into the cigarette lighter for the very first time, there was a loud pop and it started smoking. Not a good thing when you're driving on a busy road.Do not buy this product for ANY reason.
