The Transcend SuperSpeed USB 3.0 Hub is ideal for use with ultrabooks or extra thin and lightweight laptops. The hub expands a single USB 3.0 port into a total of four slots, allowing multiple devices to be operated simultaneously via the fast USB 3.0 interface. Since it is powered by the built-in cable, it does not require an additional power adapter. At the same time, its compact and lightweight design makes it the perfect travel companion.
