Should you buy a Surface Dock for Surface Go or Surface Go 2?
Say hello to the Surface Dock 2
The Surface Dock 2, released alongside the Surface Go 2, brings a much-needed update to ports and overall design. It hooks up to the Go 2 with the proprietary Surface Connect port, leaving the Go 2's USB-C port free. Unfortunately, the Surface Dock 2 doesn't work with Surface hardware released before 2017, but that doesn't rule out the original Surface Go.
On the front are two USB-C 3.2 ports, each capable of 15W of charging. The back of the Surface Dock 2 includes two USB-A 3.2, Ethernet, 3.5mm audio jack, and dual USB-C 3.2 ports for external video. It appears the dock should push dual 4K displays at 60Hz or dual 5K displays at 30Hz through the rear USB-C ports. The side also has a Kensington lock slot for added security.
While connected to your Surface device, the Dock 2 is capable of delivering up to 120W of charging. For the Surface Go or Go 2, this is far more than enough to keep the battery topped up for when you need to leave home or office.
If you'd like to keep the built-in USB-C port on your Surface Go or Go 2 free for other needs, the Surface Dock 2 should be an excellent choice. Whether you need added connectivity or boosted external display support, it will get the job done.
Updated with modern ports
The Surface Dock 2 brings much-needed updates to the original, adding in four USB-C ports alongside the usual Ethernet, USB-A, and 3.5mm jacks.
For all modern PCs
The Microsoft USB-C Travel Hub lets you take more ports on the go, expanding all modern PCs with extra USB-A, VGA, HDMI, and VGA ports in a small package.
