I always forget to charge my cell phone at my room, I do get remind of it when I am out for office or for some other work in my car, when I have to make any important call. Some time it is ok but most of the time it becomes a big problem. So I want to have a cell phone car charger. Btu in have heard that it does not works for a long time and it is almost a wastage of money. so any one of you who already using cell phone call chargers please do tell me about its performance.
