Abstract

The present invention relates to a hub device capable of supplying power, which comprises: a power input unit, a Boost/Buck unit, a power output unit, a control unit, a plurality of first electrical connection units, and a second electrical connection unit. By way of the control unit and the plurality of first electrical connection units, the hub device can provide a hub function for a plurality of the USB connectors; moreover, By means of the power input unit, the Boost/Buck unit and the power output unit, the hub device is able to supply the a portable computer with the necessary power thereof. So that, when a user goes out with the portable computer, the specific power supply of the portable computer may not be carried out; thereof, that makes the living of the user more convenient.
