StarTech TB33A1C Thunderbolt 3 to 4 Port USB 3 0 Hub

Overview

The StarTech TB33A1C is a high-performance connectivity hub designed to expand the peripheral capacity of Thunderbolt 3-equipped laptops and workstations. This bus-powered adapter utilizes the 40Gbps bandwidth of the Thunderbolt 3 interface to provide a dedicated 5Gbps controller for its four USB 3.0 (USB 3.2 Gen 1) ports. It is an essential tool for power users and IT professionals who need to connect multiple high-bandwidth devices—such as external hard drives, flash drives, and high-resolution webcams—to a single port without the data bottlenecks associated with traditional USB hubs.

Housed in a durable, compact aluminum enclosure, the TB33A1C is engineered for both desktop stability and portability. Its small footprint and integrated Thunderbolt 3 cable make it an ideal solution for mobile workstations where port availability is limited. The hub features three USB-A ports and one USB-C port, providing a versatile mix of connections for both legacy hardware and modern Type-C peripherals.

Because it is a Thunderbolt 3 certified device, it ensures a more stable and higher-speed data connection than standard USB-C hubs. The unit is plug-and-play, requiring no additional drivers or software, and is fully compatible with both Windows and macOS ecosystems. It also includes an additional Thunderbolt 3 port, allowing users to daisy-chain further Thunderbolt devices or connect a high-resolution display.
