With more and more USB 3 devices out now, here is the perfect solution to connect your new USB 3 devices as well as your old USB 2 and USB 1 devices. With the inclusion of a 240v AC adaptor and USB 3.0 cable, this USB 3 hub is capable of passing through the full 900mAmp of power (if required) to all devices. (if you dont have a powered hub, you wont get enough power by just plugging it into your PC/notebook’s USB port).
