Abstract
A portable power source is configured for use with an electronic device. The portable power source cooperates and communicates with the electronic device via a peripheral bus to which the electronic device is attachable. The portable power source includes circuitry to process a power request signal from the electronic device to determine whether a device connected to a bus interface of the portable power source is requesting power from the portable power source.
