Plus, the stylish hub features three USB 3.0 (also known as USB 3.1 Gen 1) ports in a compact housing. And, its silver, sandblasted finish provides a unique and trendy look when compared to traditional hubs.
The hub features a rugged yet lightweight housing, so there's no need to sacrifice dependability for portability. With its compact, USB-powered design and a built-in USB cable, you can tuck the combination hub neatly into your travel bag, and avoid the nuisance of carrying multiple separate adapters.
This USB 3.0 hub is perfect for travel, such as back-and-forth trips from home to office. Plus, the compact hub takes up minimal space on a desk, so you can use it in hot-desk or BYOD (Bring Your Own Device) environments.
This bus-powered USB hub installs quickly and easily, and it's natively supported in Windows, Mac, and Chrome OS, with no additional drivers or software required. You can also avoid the nuisance and cost of purchasing new devices by using the USB 3.0 hub plus GbE with your current USB 2.0 and 1.x devices.
