A hub device for overcoming limits to charging and data transmission functions thereof includes a switching unit having a switch and a switching circuit; a first electrical connection port electrically connected to the switching circuit and for an electronic computing device to electrically connect thereto; a plurality of second electrical connection ports electrically connected to the switching circuit and for portable electronic devices to electrically connect thereto to get power supply therefrom; and a power supply connection unit electrically connected to the switching circuit. Through operation of the switch, the switching circuit can switch at least one of the second electrical connection ports from a charging downstream port to a dedicated charging port while all other second electrical connection ports are maintained as charging downstream ports for data transmission or charging function. Thus, the hub device is more convenient and practical for use. |
