Systems and methods for universal serial bus (usb) power delivery with multiple charging ports

A universal serial bus (USB) charging system configured to charge a plurality of electronic devices, the USB charging system comprising:

• a power supply including a plurality of power converters and a plurality of power supply outputs electrically coupled to the plurality of power converters, respectively, each of the plurality of power converters configured to convert an input voltage to a plurality of different output voltages;
• a plurality of charging ports electrically coupled to the plurality of power supply outputs, respectively, each of the plurality of charging ports configured to connect to, and provide an output voltage selected from the plurality of different output voltages to, an electronic device;
• and
• a controller in electrical communication with the power supply and the plurality of charging ports, the controller comprising:
• one or more processors;
• and
• a memory having stored thereon instructions which, when executed by the one or more processors, cause the controller to:
• communicate information regarding the plurality of different output voltages to first and second electronic devices via respective first and second charging ports of the plurality of charging ports;
• receive, via the respective first and second charging ports, information regarding first and second output voltages selected from the plurality of different output voltages by the respective first and second electronic devices;
• and
• control the power supply to provide the selected first output voltage to the first electronic device and to provide the selected second output voltage to the second electronic device.
