3-Port Portable USB 3.0 Hub plus Gigabit Ethernet Aluminum with Built-in Cable
Product ID: ST3300GU3B
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. This hub is an ideal laptop accessory for your Microsoft Surface™ Pro 4, Surface Pro
3, Surface Book, Dell™ XPS 13, and many other devices.
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 5Gbps
capabilities of the USB 3.0 interface to provide wired Gigabit access that is fully compatible with IEEE
802.3/u/ab standards. Plus, the GbE port supports Wake-on-LAN (WOL), so you can remotely wake your
computer over your network.
