Abstract
A charger including a USB type-C input port configured to receive power from a power supply, a plurality of output ports each configured to couple to one of a plurality of devices to be charged, and a control logic circuit operatively coupled to the plurality of output ports and configured to manage power to the plurality of output ports. The control logic circuit is hardwired to prioritize power to a first output port of the plurality of output ports when the output port is coupled to a device such that an amount of the received power is allocated to the output port instead of at least one of the plurality of output ports that is coupled to a second device and the control logic circuit does not include an electronic processor.
