1. 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 an analog data signal for use by the electronic device to control an amount of power drawn by the electronic device; and
a cable having proximal and distal ends, the proximal end being electrically coupled to the adapter and the distal end terminating in an output connector, the output connector including;
a plurality of conductors to transfer the DC power and the analog data signal to the electronic device; and
circuitry to receive a data request from the electronic device and in response transmit a data output to the electronic device to identify the power supply equipment to the electronic device.
