Tripp Lite's U360-007 USB 3.0 Charging Hub plugs into a computer's USB 3.0 port and provides seven USB 3.0 Super-Speed peripheral ports, and one charging port for charging tablets such as an iPad. Dedicated charging port supplies the extra amperage needed to charge tablets, which most USB hubs do not include. Plug-and-Play... no software or drivers required. Automatically switches to the highest speed supported by the peripheral. Windows (compatible with Windows 8) and Mac compatible. Use only the external power supply that comes with your hub. Beginning in the fall of 2015, a 12V 2A power supply will be included with the U360-007, whereas previous units included a 5V 4A power supply. The power spec printed under the DC jack on your hub will match the spec of the included power supply.
