Abstract
Systems and methods for universal serial bus (USB) power delivery with multiple charging ports or connectors to charge multiple electronic devices. The systems include a power supply having converter(s) that converts an input voltage to different output voltages and outputs; charging ports electrically coupled to the power supply outputs; and a controller electrically coupled to the power supply and the charging ports or connectors. Each of the charging ports is configured to connect to and provide an output voltage selected from the different output voltages to an electronic device. The controller communicates or publishes information regarding the different output voltage levels that can be provided by the power supply to the electronic devices; receives voltage levels selected by the electronic devices via the charging ports; and controls the power supply to provide the selected voltages to the first and second device, respectively.
