Hub device and power supply method thereof

A hub device, comprising:

• a power input port, connected to a power adapter;
• a first power output port and a second power output port;
• a power management circuit, coupled to the power input port, the first power output port, and the second power output port;
• and
• a controller, coupled to the power input port, the first power output port, the second power output port, and the power management circuit,
• wherein when a first electronic device and a second electronic device are respectively connected to the first power output port and the second power output port, the controller determines an input electric power from at least one default supply power of the power adapter based on first operating power information of the first electronic device and second operating power information of the second electronic device, and the controller controls the power adapter to provide the input electric power to the power input port,
• wherein the power management circuit receives the input electric power to generate a first operating power and a second operating power, and the power management circuit outputs the first operating power to the first power output port and outputs the second operating power to the second power output port,
• wherein the power management circuit comprises:
• a power converting circuit, coupled to the controller and the power input port, wherein the power converting circuit is configured to receive the input electric power and to generate at least one output electric power;
• and
• a switch device, coupled to the controller, the power converting circuit, the first power output port, and the second power output port, wherein the switch device is configured to receive the at least one output electric power,
• wherein the controller determines a voltage value of the at least one output electric power based on the first operating power information and the second operating power information to control the power converting circuit to generate the at least one output electric power, and
• wherein the controller controls a switching state of the switch device based on the first operating power information and the second operating power information, such that the switch device outputs the first operating power to the first power output port and outputs the second operating power to the second power output port based on the at least one output electric power.
