The ST3300GU3B Portable USB 3.0 Hub features an integrated GbE port, enabling you to expand your laptop connectivity by adding three external USB 3.0 ports, as well as a Gigabit network port via a single USB 3.0 connection.

The hub merges Gigabit network support and USB 3.0 hub access into lightweight yet sturdy aluminum casing, providing vital connectivity ports that are often limited or nonexistent on modern mobile computers, while remaining compact and travel-friendly. Plus, with an attached USB 3.0 host connection cable there’s no need to carry a separate cable with you, so you can tuck the hub neatly into your laptop bag for maximum portability.

For faster and more consistent network connections, the integrated Ethernet port leverages the 5 Gbps capabilities of the USB 3.0 interface to provide wired Gigabit access that is fully compatible with IEEE 802.3/u/ab standards.

An ideal laptop accessory, this mobile USB hub is great for connecting low-power peripherals like a mouse, keyboard or USB flash drive, and also includes a universal power adapter for connecting devices such as external hard drive enclosures.

Backed by a 2-year warranty and free lifetime technical support.
