Surface Go with docking station.
Ports on the side of the Surface Go, from left to right, headphones, USB-C and power.
The Surface Go with docking station has two bricks on the power cable. The first is power, the second is the docking station itself.
The power cable detaches from the power brick. From the brick it goes into the docking station.
NOTE: We will be updating this page once some new hardware options are confirmed so you can see what the "set up" looks like with a cash drawer, receipt printer, customer display, and payment terminal.
