description An auxiliary power supply (150) includes an auxiliary battery (152), power supply circuitry (154), and a connector (108b). The power supply circuitry (154) supplies an output which provides electrical energy for powering the electrical circuitry (102) of a battery powered device (100) and for recharging a battery (104) associated therewith. In one embodiment, the power supply circuitry (154) supplies an output current which is a function of the charge state of the auxiliary battery (152) and a load current presented by the electrical circuitry (102).
