The cradle also features a spare battery charger - great to have if you have multiple batteries. If you want to use the cradle's spare battery charger, you also need to connect the bundled AC adapter. The AC adapter does not charge the Touch, it only provides power to the battery slot.
**NOTE: BATTERY CRADLE WILL NOT CHARGE OR FIT AN Alltel Touch, HTC Touch, Sprint Touch, Verizon or XV6900 WITH AN EXTENDED BATTERY DOOR.
