Adds eight ports including 4K HDMI, Thunderbolt 4 with 100W charging, USB-C data, audio, two USB 3.0 and card slots to Surface Pro 9, 8 or X
This docking station is built exclusively for Microsoft Surface Pro 9, Pro 8 and Pro X devices. It converts the two native USB-C ports into eight connections including video, data, audio and card readers. Professionals who carry a Surface Pro and need a single-cable desk setup are the target users. It will not fit any other laptop or tablet model.
The hub drives two external displays simultaneously — one through HDMI at 4K resolution and the other via the Thunderbolt 4 port at up to 8K@30Hz. Both video streams remain stable during long editing or coding sessions because the upstream Thunderbolt 4 link supplies 100 W power delivery while moving data at 10 Gbps. Thermal throttling is not described in the supplied data.
The single specification that decides compatibility is the 100 W USB-C Thunderbolt 4 port which handles display, data and power delivery together. If your workflow requires charging the Surface while driving two monitors and peripherals, this port covers it. Buyers who need more than two video outputs or a different charging profile should look elsewhere.

The dock draws power through that port to charge the Surface while driving displays and peripherals, so it runs warm but stays within normal operating limits.
Your Surface Pro 9, Pro 8 or Pro X needs its two built-in USB-C ports side by side; the hub plugs directly into both.
Yes, the HDMI port delivers 4K at 30 Hz and the Thunderbolt 4 port can drive a second display, so a 1080p screen works alongside a 4K one.
