Abstract

A portable battery powered appliance such as a flashlight accepts at least first and second batteries (1021, 1022). The appliance also includes an electrical load (110) such as a light source. A first circuit (1041) such as a DC to DC converter receives power from the first battery (1021) and supplies power to the load (110). A second circuit (1042) such as a DC to DC converter receives power from the second battery (1022) and supplies electrical power to the load (110). In one embodiment, the appliance accepts batteries (102) having multiple physical sizes.
