USB4 Docking Station for Multiport Workstations

This USB4 docking station converts a single USB-C or Thunderbolt 4 port into a multiport workstation for laptops, tablets and smartphones. It supports simultaneous video output, data transfer and power delivery for PD-compliant host devices. The compact grey adapter is designed for professionals who need to connect external displays and peripherals through one cable.

Bandwidth and Display Limits of the USB4 Interface

The dock delivers full 40 Gbps data transfer rates when connected to a USB4 or Thunderbolt 4 Type-C port. Video output is limited to a single 8K display at 30 Hz or dual 4K displays at 144 Hz via DisplayPort Alternate Mode. Systems without USB4 or Thunderbolt 4 connectivity will not achieve the stated bandwidth or resolution targets.

26 W Charging Capability Decides Suitability

The unit provides 26 W of power delivery to charge the host device while in use. Buyers whose laptops require higher wattage for operation under load cannot rely on this dock as a sole power source. It is unsuitable for users needing more charging power than the rated output.

Questions about this item

Should I pick the single 8K 30Hz mode or the dual 4K 144Hz setup for my monitors?

Choose single 8K at 30 Hz when you need maximum pixel count on one screen; choose dual 4K at 144 Hz when you prefer two high-refresh displays for gaming or multitasking.

What does the 40 Gbps rating actually deliver when I plug this dock into my laptop?

The 40 Gbps USB4 link carries video, data and power simultaneously, so you get full-speed peripheral transfers while driving 8K or dual 4K output and charging the host.

Does the Thunderbolt 4 connection limit the 40 Gbps bandwidth in any real-world scenario?

Thunderbolt 4 certifies the full 40 Gbps pipe, so the dock sustains that throughput for combined video, USB data and power delivery without protocol overhead reducing the usable rate.
