ABSTRACT:
A product such as a portable radio adapted for operation from either an internal battery source or an external source of relatively high voltage alternating current electric power is provided with a removable power module containing all of the high voltage components required for operation from the alternating current source. The removable power module is connected to the product by a low bulk, low voltage electrical connector through a recess in the product housing, the recess being sized to receive both the power module and the electrical connector when battery operation is desired. Because of the low bulk of the electrical connector, the size of the recess may be minimized.
