Patent ID: 8330303

Claim:
Power supply equipment comprising: an adapter to convert power from a power source, external to the adapter, to DC power for powering an electronic device, the adapter including circuitry for producing a data signal for use by the electronic device to control power flow within the electronic device; a cable having proximal and distal ends, the proximal end being electrically coupled to the adapter and the distal end terminating in a connector; and a plurality of tips, each tip including: an input connector which is detachably mateable to the connector to receive the DC power and the data signal; an output connector which is detachably mateable to at least one corresponding electronic device; and at least three conductors to transfer the DC power and the data signal from the input connector to the output connector to provide the DC power and the data signal to the at least one corresponding electronic device, wherein the output connector has a shape and size dependent on the shape and size of a power input opening of the at least one corresponding electronic device.
