Abstract
Systems, methods and apparatus for charging a two-terminal portable electronic device. In one example, the system, method, and apparatus include detecting, with a detection circuit, the two-terminal portable electronic device and electrically coupling the two-terminal portable electronic device to a multi-pin universal serial bus connector when the two-terminal portable electronic device is coupled to a receptacle provided by a charger; and charging, with an activation circuit, the two-terminal portable electronic device using a configuration channel terminal of the multi-pin universal serial bus connector upon detection of the two-terminal portable electronic device.
