This 4-port portable USB 3.0 hub with built-in cable turns a single USB 3.0 port into four, letting you connect more of your devices to your computer. The hub features a built-in cable that is longer than what most traditional hubs offer. The extended-length cable gives you the flexibility to place the hub and your devices exactly where you want them, and it ensures the hub can connect to your laptop or tablet regardless of where the laptop's USB 3.0 port is located.
