Know your gear

This Thunderbolt 3 USB 3.1 multi-channel hub controller delivers maximum USB performance, adding four high-speed independent USB ports to your Thunderbolt 3 laptop. It provides three dedicated USB controllers and up to 20 Gb/s of aggregated bandwidth for USB devices. The Thunderbolt 3 hub lets you access multiple USB devices at greater bandwidth.

Maximize USB Performance

The high-speed USB hub provides two 10 Gb/s ports for connecting high-performance devices such as storage arrays, 3D scanners, audio-video devices and external SSDs, with dedicated bandwidth for faster read/write access. The second Thunderbolt 3 port can be used to connect an additional USB-C device with up to 10 G bandwidth.


Dedicated Independent Port Bandwidth

When only one USB port is in use, the full 10 Gb/s bandwidth is available. Two additional USB-A ports provide 5 Gb/s of bandwidth to each device simultaneously, making them ideal for portable hard drives or flash drives. For added convenience, the front USB-A port supports both data and charging of your mobile device.


Extend Your Workstation

The Thunderbolt 3 hub features a second Thunderbolt 3 port to connect an additional display to your laptop (a USB-C video adapter may be required). The port can also be used to connect additional Thunderbolt devices, with the choice of daisy-chaining up to six devices.

The TB33A1C is backed by a 2-year warranty and free lifetime technical support.
