Add up to 4 peripherals quickly and easily with the Sabrent 4-Port USB 3.0 Hub [$15.99] . Its thin, lightweight design makes it the perfect travel companion to expand one USB 3.0 port into four. These days, notebooks are coming with only a few ports but you often need to attach several USB devices at once. It’s fully backwards compatible with both USB 2.0 and 1.1 products. Each port has its own separate power switch which allows you to control each port individually.
