USB Bluetooth Hub is not only an ordinary hub, but also a Bluetooth dongle at the same time. You can connect any other USB devices with the 3-port hub and interact with Bluetooth devices by its Bluetooth function. You may wonder there are obviously built-in 4 ports in the hub, how come call it 3-port hub? Actually, there are 3 ports for connecting devices with the computer for data transfer, the remaining port provides power for devices. It is good for connecting USB lamps, USB fans, USB Ionizers, etc.
