The dock is a useful accessory for the tablet which may charge the tablet battery and/or enhance audio output while continuing to allow display of the device.
As with any stand-style tablet case, the proper charging station-style dock should be constructed of sturdy material which provides good grip on a flat surface. All ports should be accessible and the fit of the device in the docking frame must be tight. Prospective buyers who are video-first users should also note whether the stand of the dock may be easily switched from portrait to landscape mode, a feature sometimes offered.
Material composition of tablet dock varies as much as the design of such accessories, but is typically made of the sturdiest material possible. Owners of non-Apple tablets may find a slightly smaller selection in docks for their devices, but some choices exist.
