Thunderbolt 3 certified mini dock

This Thunderbolt 3 certified mini dock connects to Windows or Mac laptops through a single port. It adds two HDMI video outputs, two USB Type-A ports and a Gigabit Ethernet connection. The unit is bus powered and designed for small or shared workspaces.

28 cm attached cable and dual 4K 60 Hz HDMI

The 28 cm attached cable gives extra reach to reduce strain on the laptop port when the dock sits on a riser. Two HDMI ports each drive a 4096 x 2160 display at 60 Hz. One USB 3.2 Gen 1 port runs at 5 Gbps and one USB 2.0 port handles legacy peripherals.

Single Thunderbolt 3 port with 40 Gbps throughput

All video, data and Ethernet traffic shares one 40 Gbps Thunderbolt 3 link to the host. Macs with Apple M1 chips support only a single external display through this dock. Buyers who need more than two video outputs or higher per-port bandwidth should consider a larger dock.

Questions about this item

Will the attached 28 cm Thunderbolt cable need replacing after frequent travel use?

The 28 cm cable is permanently attached; if it becomes damaged the whole unit must be replaced as the cable cannot be swapped separately.

What throughput ceiling appears first when both 4K 60 Hz HDMI displays and the USB 3.2 Gen 1 port are active?

The shared 40 Gbps Thunderbolt 3 link carries all video and data, so combined display and peripheral traffic hits that 40 Gbps aggregate limit first.

How warm does the bus-powered enclosure get when driving dual 4K monitors and Gigabit Ethernet all day?

The compact aluminium body acts as a passive heatsink; sustained dual-display and Ethernet loads make it noticeably warm but it remains within normal operating temperature.
