The 6-Port SuperSpeed USB 3.0 Hub from IOGEAR provides Windows, Mac, and Linux systems with six USB 3.0 ports. You can expand the functionality of your computer by using a single USB port to connect with six USB devices. The hub connects to your computer with the included 6' USB 3.0 cable, and an external power adapter powers the hub. Once connected to your computer, each USB port delivers data at a rate of 5 Gb/s and is backwards compatible with 2.0 and 1.1 devices. It can also charge USB battery-powered devices by outputting 1.3A, even when the computer is turned off. Furthermore, the hub is built with over-current protection that safeguards your data and devices from power spikes and surges.
