Abstract
An interim power source includes an energy storage, a switch coupled with the energy storage, and a control circuit coupled with the switch. The switch selects a source of power being delivered out of an output power terminal to an electronic device. The control circuit may cause the switch to select the source of power from at least one of an input power terminal and the energy storage. The input power terminal may include a main power source and a backup or secondary power source.
