A detachable tip is used in conjunction with a power adapter to provide DC power to an electronic device. The tip includes an input connector which detachably mates with a connector which is electrically coupled to the power adapter. An output connector of the tip detachably mates with the electronic device. Conductors within the tip transfer the DC power from the input connector to the output connector to provide the DC power to the electronic device. Circuitry within the tip transmits 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.
