Abstract

Charging a device using a plurality of handshakes. A first device may provide a first handshake to a second device. A device of a first device type may be configured to charge its battery without further communication based on the first handshake. The first device may monitor a connection to the second device for a second handshake corresponding to a device of a second device type. In response to detecting the second handshake, the first device may provide a response to the second device. Accordingly, the second device of the second device type may be configured to charge its battery based on the second handshake.
