Just my own thoughts on this subject matter, has anyone not gotten a car charger? I got myself a Kingston car charger and it works great to charge iPhone during emergency cases....

Sure beats plugging a battery pack or carrying an additional phone...

Still, be wary of any "china" or "unbranded" units as the circuit may fry your iPhone charger board, and that one will cost arnd RM500 for replacement....

I'd rather be planning my daily usage and charge my iPhone at night and leave it, and get 100% when i remove it in the morning...

And no, the iPhone will cut off the charging once it is full, u can see the battery icon will show a wall socket logo in it.
