Abstract
A Charging unit for a cellular telephone is provided with having means for connection to an electrical power source and a charging circuit for delivering a charging current to a battery pack or the cellular telephone itself, if the cellular telephone includes an internal energy retaining mechanism (e.g., charge storage device such as a battery). The charging unit further includes a plurality of electrical contacts in electrical communication with the charging circuit. Finally, the invention includes at least one user-selectable switch and at least one electrical contact in electrical communication with the at least one user-selectable switch. In accordance with another aspect of the invention, a cellular telephone is provided, wherein the telephone includes a sensing circuit configured to detect the presence of a charging unit. It further includes a circuit configured to identify from the charging unit a designated number to which to forward incoming calls to.
