Kensington worked directly with Microsoft to provide professional-level connectivity that looks as good as it functions, so you can work like a pro. Connect with confidence for a seamless dock and charge experience.


This Thunderbolt-certified desktop docking station is the first of its kind, providing the ultimate plug-and-play solution for USB4/Thunderbolt 4 Surface devices, while also supporting USB-C and USB-A accessories.

Thunderbolt 4 Technology

For the first time, this Thunderbolt 4 modern docking station can connect up to three additional Thunderbolt devices directly (up to five in total via daisy chain) while providing transfer speeds up to 40Gbps, up to Dual 4K video output, and audio; all through the included 0.8m Thunderbolt 4 cable, for a quick and powerful plug-and-play experience. Intel VT-d DMA protection blocks peripheral devices from unauthorized access to system memory.
