Here's an ordinary USB car charger connected to an Ipad Mini. The result : The Ipad mini battery is charged normally as it's connected with an original but expensive Apple car charger.

Charging the Ipad Mini with an ordinary USB car charger

This USB car charger takes 12 to 30 Volts DC and converts it to 5 Volts DC with a maximum current of 1 Amp. (5 Watts) The USB car charger is power full enough to charge the 16.3 Watt Ipad battery. The Ipad Mini AC battery charger has the same output power rating.

This in contrast to USB ports of the older computers and laptops, which can't supply enough current to charge the 16.3 Watt battery within the normal charge time. The Ipad Mini then comes up with a notification "not charging" - which is a bit confusing because it does charge the Ipad Mini battery only at a very slow rate.
