The USB hub with four USB 2.0 ports from A4tech is a handy device that makes a great addition to a computer, notebook or netbook that has a limited number of ports. You can use the USB hub for many peripheral devices, such as a flash disk, smartphone, tablet, or a mouse or digital camera. Thanks to its compact size, you can bing it with you everywhere. It fits easily in any bag. And it is, of course, backwards-compatible with USB 1.1.
