1. A method for providing DC power from an alternating current AC source comprising the steps of:
- identifying an AC connector configured to be connected to an AC source;
identifying a DC connector configured to be connected to the DC power receiving device;
within a power supply attached between the AC connector and the DC connector, receiving a carrier wave from a DC power receiving device, wherein the carrier wave includes digitally encoded signal data specifying power requirements for the DC power receiving device;
extracting from the digitally encoded signal data specifying power requirements for the DC power receiving device;
automatically adjusting electronics in the AC source in accordance with the power requirements; and
providing power via the DC connector to the DC power receiving device supplied by the AC source through the AC connector, the provided power approximately conforming to the power requirements, where approximately conforming signifies that conformance is within a previously established range.

Abstract
A power supply including a power supplying connector, a direct current (DC) connector, an information extractor, power adaptor electronics, and variable voltage electronics. The information extractor being configured to extract digitally encoded data from a carrier wave. The digitally encoded data can specify power requirements of the DC power receiving device. The variable voltage electronics can adapt DC power generated by the power adaptor in accordance with settings provided by the information extractor. This adapted power can be provided to the DC power receiving device connected to the power supply via the DC connector.
