> about car chargers, I found out when my battery died that they draw battery power even when the phone is not connected if it is plugged into a cigarette lighter. That depends: many vehicles switch the power-plugs with the ignition, and supply NO power to them when the key is out, or even just not turned on. > I also tried to power my phone and I think I blew a fuse because none of my lighters were working. The iPad draws 2.1 amps, the iPhone only 1. A typical resistance-heater lighter draws 10 or 15 amps. The fuse may be blown, but probably because of some other damage, like a short in a charging cord, or a lighter, or the socket itself.
