Microsoft Surface Thunderbolt 4 Dock

The Microsoft Surface Thunderbolt 4 Dock T8H-00001 is a new docking station designed for professionals who need a single-cable workspace. It delivers up to 90W power delivery to charge compatible laptops while connecting peripherals. This black dock suits users who require high-speed data transfer and dual 4K monitor support from one compact hub.

Eight versatile ports expand connectivity

Three USB-C ports with Thunderbolt 4 provide up to 40Gbps data transfer for fast file moves and high-resolution displays. Three USB-A ports accommodate legacy accessories, while a 2.5G Ethernet jack adds wired networking. A 3.5mm audio jack handles headsets, and a security lock slot helps protect the device in shared environments.

Sustainable enclosure with practical mounting

The dock and its power supply enclosures use 20% ocean-bound plastic, reflecting a focus on recycled materials. Its small footprint fits tidily on a desk, and the security lock slot allows physical tethering for peace of mind. The single Thunderbolt 4 upstream cable carries video, data and 90W charging simultaneously.

Questions about this item

Will the 90 W power adapter need replacement after a few years?

The 90 W power supply is built into the dock enclosure and is covered by the standard Microsoft hardware warranty; no user-replaceable parts are specified.

Which port hits its bandwidth ceiling first when I run two 4K monitors and the 2.5 Gb Ethernet at the same time?

Each Thunderbolt 4 port runs at 40 Gbps, so the 2.5 Gb Ethernet and dual 4K video streams share that pool without saturating it.

How hot or loud does the dock get when it charges a laptop at 90 W all day?

The dock uses passive cooling with no fan, so it runs silently; the enclosure may become warm to the touch during sustained 90 W charging.
