A dual input battery assisted power converter ( ) which provides a continuous, regulated DC voltage output to a user-connected mobile device, such as, a lap top computer or a cell phone, for example. The power converter ( ) comprises a power supply circuit ( ) and a separate, detachable power storage circuit comprising a battery pack ( ) having a re-chargeable battery ( ). The power supply ( ) is adapted to deliver a pair of regulated DC output voltages, of opposite voltage potentials, to a pair of respective output terminals. Preferably these output voltages are derived from two external input voltages: an AC input voltage and a DC input voltage. Advantageously, if both of the external input voltages are temporarily removed, the battery pack ( ) will advantageously serve as a substitute DC input power source, thereby allowing the power supply ( ) to deliver the same regulated DC output voltage to the user-connected mobile device without interruption. Moreover, once either of the external input voltages are again re-established, the battery pack ( ) automatically taps the output terminal of the power supply ( ) at a node to recharge the battery pack ( ).
