The Surface Dock and Surface Dock 2 are accessories that allow you to connect multiple devices and peripherals to your Surface. You can attach devices like keyboards, mice, and webcams and push your Surface device's display output to multiple external monitors.
Both docks also have Ethernet ports, allowing you to have a rock-solid connection to the internet. The device allows you to set up dock a permanent environment with of your devices and accessories and then plug the dock into your Surface using the Surface Connect port.
Specifications
The Surface Dock 2 is a few years old now, but has USB-C ports to work with modern devices, has better charging capabilities, and better support for external displays. It even has a longer cable than the original dock to make it easier to connect your Surface to the dock.
The Surface Dock 2 can power two 4K displays at once at 60Hz or two 5K displays at once at 30Hz. It also has a total power delivery of 199W, and 120 of those watts can charge your Surface device. The remaining 79W can help charge accessories attached to the dock.
In contrast, the original Surface Dock has a much lower set of specs. When pushing to external displays, the original Surface Dock caps at 4096x2160 at 30Hz or 2960x1440 at 60Hz. It also has a lower 90W for power delivery. As a result, the Surface Book 2 can sometimes drain power even while charging.
