Portable Thunderbolt 3 Dock for USB-C Laptops

This docking station adds DisplayPort, HDMI, VGA, one USB-C data port and two USB-A ports through a single USB-C connection that is Thunderbolt 3 compatible. It supplies up to 100W of power delivery to charge the host laptop while driving external displays and peripherals. The lightweight aluminium chassis includes a detachable cable for travel use.

Multi-Stream Transport Limits Video Configurations

Multi-Stream Transport technology enables one 4K display, two 1080p displays or three 720p displays across the video outputs. Using all three video ports simultaneously in extended mode requires the host GPU to support at least three external displays. Video wall arrangements also depend on AMD Eyefinity, Intel or NVIDIA Surround graphics adapters.

Mac M1/M2/M3 Pro/Max Restricted to Single Extended

On Mac computers with M1, M2 or M3 Pro and Max chips the dock delivers only a single extended video output regardless of the number of connected monitors. Windows 10, 8 and 7 systems can use the full multi-display capability when the graphics hardware allows it. Buyers needing multiple extended screens on base-model Apple silicon should choose a different solution.

Questions about this item

Should I pick the HDMI, DisplayPort, or VGA output for my setup?

Choose based on your monitor inputs; HDMI or DisplayPort give one 4K display, while any two of the three ports can drive two 1080p screens, and all three together support three 720p outputs.

What does the 100W power delivery actually provide when the dock is connected?

The dock passes up to 100W through its USB‑C port to charge the host laptop while simultaneously running the video and data ports.

How does the Thunderbolt 3 compatible USB‑C link limit the data ports in practice?

The two USB‑A ports and the extra USB‑C data port each run at USB 3.1 Gen 1 speeds up to 5Gb/s, which is the maximum bandwidth the host connection allows for data.
