Overview

The StarTech.com ST3300G3UA is a compact 3-port USB 3.2 Gen 1 (5Gbps) hub with an integrated Gigabit Ethernet adapter. Designed for ultrabooks and laptops with limited ports, it adds three USB-A ports and a wired RJ-45 network connection in a single bus-powered enclosure. The aluminum housing is durable and travel-friendly, and the hub works without external power or drivers.

Connectivity & Compatibility

The hub provides three USB-A ports with up to 5Gbps data transfer, backward compatible with USB 2.0/1.1 devices. The built-in Gigabit Ethernet port supports Wake on LAN, jumbo frames, and VLAN tagging. It is compatible with a wide range of operating systems including Windows, macOS, Linux, ChromeOS, and Android, requiring no driver installation. Overcurrent protection (OCP) is included for safety.

Product Info

Released around 2020, the ST3300G3UA remains relevant for users needing reliable wired networking. It carries a 2-year manufacturer warranty and lifetime free technical support. At roughly $45–50 (or ¥6,700 in Japan), it sits in the entry-to-mid range, offering excellent value for its combination of hub and LAN adapter.

Best Use Cases

  • Laptop users in unstable Wi-Fi environments: the integrated Gigabit Ethernet provides a stable, low-latency connection for remote work or online gaming. - Ultrabook owners with few ports (e.g., MacBook, Dell XPS): expands connectivity with three USB-A ports plus wired networking without bulky adapters. - Travelers and hot-desk workers: eliminates the need for separate hub and LAN adapter; bus-powered design means no extra power brick. - Multi-OS users: plug-and-play across Windows, macOS, Linux, ChromeOS, and Android. Not ideal for users requiring USB-C inputs, USB 3.2 Gen 2 speeds, or high-power charging (since it is bus-powered).
