I have this dual port USB car charger. One port is 1A, the other is 2.1A. It is advertised for phone vs. iPad charging, but I was wondering: Would charging the 920 at the 2.1A port do any damage? Would it be faster? Or, it just wouldn't make any difference. I
I am told Ipad chargers don't work well with other devices and wont charge them properly. On a separate note the 2A charger will not damage the phone because max charging current is controlled by the phone itself. Just have to make sure the voltage match. I find my 2A chargers are faster but not necessarily twice as fast.
