Here's a must-have accessory for your MacBook. This portable USB 3.0 hub merges your USB peripheral and RJ45 network connections into a single, convenient combination hub. It gives you two vital connection types that are often missing from modern, port-limited laptops. This silver, sandblasted USB hub matches the finish of your MacBook, and because it features a solid-aluminum casing that's both lightweight and rugged, it's perfect for travel usage. This high-quality, Apple style USB hub features a Gigabit Ethernet port, giving you an easy way to expand your MacBook connectivity. And because the hub integrates a Gigabit Ethernet port, you can add wired network connectivity to your laptop in a location where Wi-Fi is unreliable or unavailable. Its silver, sandblasted finish provides a unique and trendy look when compared to traditional hubs. Plus, the stylish hub provides three USB 3.0 (also known as USB 3.1 Gen 1) ports in a compact housing, without compromising on portability or design. 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 10 and 8.1, as well as Mac OS 10.11 and 10.10, 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. The ST3300G3UA is backed by a StarTech.com 2-year warranty and free lifetime technical support.
