Add up to 4 devices quickly and easily with the Sabrent HB-UMN4 USB 2.0 Rotatable Hub.

Achieve full 480 Mbps on each port, or daisy chain multiple hubs to a maximum of 127 devices. Fully backwards compatible with the USB 1.1 products
For a stable connection, the devices connected to the 4 Port Hub must not exceed a combined current of 5 volts 500mAh. External hard-drives should be connected to an external power source. This 4 Port hub will not charge an iPad (it will only sync).
