IPad Dock

The original iPad Dock was a peripheral that was released by Apple for the 1st-generation iPad 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.

Though this dock was designed specifically to support the thickness of the original iPad, users found that it will also accommodate the thinner iPad 2 and 3. However, users also found that the 30-pin dock connector will be unable to reliably connect with an iPad that is inside a thick case.
