1. A universal serial bus (USB) charging system, comprising:
a power supply including a plurality of power converters connected electrically parallel to one another 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 output voltages;
a plurality of charging ports electrically connected with the plurality of power supply outputs, respectively, each of the plurality of charging ports configured to provide an output voltage selected from the plurality of output voltages to an electronic device;
a temperature sensor; and
a logic circuit in electrical communication with the power supply and the plurality of charging ports, the logic circuit configured to provide direct feedback to the power supply to output a particular output voltage of the plurality of output voltages to the plurality of charging ports, the logic circuit configured to regulate a wattage delivered to two or more charging ports of the plurality of charging ports,
wherein the logic circuit is in electrical communication with the temperature sensor and the logic circuit is configured to detect a temperature of the two or more charging ports of the plurality of charging ports and reduce a wattage delivered to a particular charging port of the plurality of charging ports if a temperature detected in the particular charging port of the plurality of charging ports exceeds a predetermined threshold.
