Systems and methods of providing power through a Universal Serial Bus connector are provided. A charging system comprises an interface configured to receive power, a power converter coupled to the power source interface, the power converter configured to use the received power to generate power output, and a charging controller configured to control an amount of power provided at the USB connector on the power lines derived from the power output, and configured to generate an identification signal on the USB connector's two data lines, the identification signal usable to indicate the charger is not subject to standard USB power limitations, the identification signal provided through the use of a resistance between the D+ and D&#x2212; data lines.

Charger system and method

Systems and methods of controlling a charging status indicator in a charging system for a device having a rechargeable power supply are provided. The charging system determines whether a device connected thereto supports remote control of the charging status indicator, and controls the charging status indicator as directed by the device where the device supports remote control of the charging status indicator.
