Detachable tip for communicating with adapter and electronic device

摘要

A tip for transferring DC power generated by an adapter to an electronic device, the tip comprising: an input connector which is detachably mateable to a connector which is electrically coupled to the DC power generated by the adapter; an output connector which is detachably mateable to the electronic device; a plurality of conductors to transfer the DC power from the input connector to the output connector to provide the DC power to the electronic device; and power indication circuitry to transmit to the electronic device via the output connector a power output indication signal representative of an amount of power available to be supplied to the electronic device by the adapter.
