Apple iPad Dock

The Apple iPad Dock (formerly Apple iPad 2 Dock) was a peripheral that was released by Apple for the iPad 2 on April 3, 2010.

Usage
The back of the dock features a line-out headphone jack and a pass-through 30-pin dock connector to attach a USB charger or other peripherals, such as an iPad Dock Connector to VGA Adapter.

This dock was designed specifically to support the thickness of the iPad 2 and 3. Users found that the tight tolerances do not allow an iPad to be docked while inside a case or protected by a Smart Cover.
