A docking station for a wireless communication device, such as a cellular telephone. The docking station includes a cradle for the cellular phone and comprises an associated LCD that enhances the video display capabilities of the cellular telephone. When docked, the cellular telephone draws power from a voltage supply provided by the docking station. While the cellular telephone is docked, a charging circuit recharges the cellular telephone battery. The docking station may be disconnected from an AC outlet so that the docked cellular telephone retains both enhanced display capabilities, which prove to be highly desirable for applications such as Internet access, as well as its inherent portability. Even in the portable mode, where the docking station is disconnected from the AC outlet, the docking station recharges the cellular telephone battery.
