Compact Thunderbolt 3 Dock

This five-port Thunderbolt 3 docking station adds dual 4K display output, Gigabit Ethernet and three USB ports to a laptop through a single cable. It draws power from the host so no external adapter is required. The aluminium enclosure measures 0.70" x 2.60" x 4.90" and weighs 0.33 lb.

Dual-display mobile workstation users

Professionals who need two external monitors at 60 Hz, wired networking and legacy USB-A peripherals while travelling will appreciate the bus-powered design. Users who require Thunderbolt downstream ports, DisplayPort outputs, SD card slots or 100 W laptop charging should look at larger mains-powered docks.

40 Gb/s host bandwidth

The single upstream Thunderbolt 3 connection provides up to 40 Gb/s of shared bandwidth for video, data and Ethernet traffic. If the host port is limited to 20 Gb/s or USB 3.2 10 Gb/s, dual 4K 60 Hz output may not be achievable.

Questions about this item

Does my laptop need a Thunderbolt 3 port to run this dock?

Yes — the dock connects through a Thunderbolt 3 cable and draws power from that port, so the host must provide a Thunderbolt 3 connection.

Can I keep using my older USB 2 keyboard and mouse with the dock?

The dock includes a dedicated USB 2.0 port designed for keyboards, mice and similar low-speed peripherals.

How do I verify both HDMI ports are delivering 4K at 60 Hz after setup?

Open your OS display settings and confirm each external monitor reports 4K resolution at 60 Hz; play protected 4K video to check HDCP 2.2 handshake works.
