Best answer: The Surface Dock, connected with the proprietary Surface Connect port, will undoubtedly work with the Surface Pro 6. The lack of USB-C and Thunderbolt 3 on the Pro 6 means you can’t use more modern docking stations, but you’ll still get plenty of extra ports with the Surface Dock, and it’ll charge your Pro 6 while connected.
The Surface Dock has been around for a few years now, and its selection of ports is beginning to show its age. However, they’re still perfectly functional; you get four USB-A 3.0, two Mini DisplayPort, a 3.5mm audio jack, and Ethernet for a wired connection.
While you’re not going to get standard DisplayPort, HDMI, or USB-C, you can still connect a couple of external displays (one at 4K with 60Hz refresh rate, two 1440p at 60Hz, or two 4K at 30Hz) to create a grounded workstation when you don’t have your Pro 6 out in public.
The Surface Dock connects with a proprietary Surface Connect port, leaving the USB-A port built into the Pro 6 free for connecting other devices straight to the tablet.
The Surface Dock charges your Surface Pro 6 while connected
The Surface Connect port is usually used to charge your Pro 6, but with a Surface Dock in the mix, that port is reserved. Luckily, the Dock — which requires a wall outlet for power — will charge your Pro 6 while connected. This means you probably won’t have to worry about whether or not your device has enough battery to last through an excursion when you leave your workstation behind.
The Surface Dock’s four USB-A 3.0 ports likewise offer 7.5W of charging power, so compatible accessories attached to the dock will also receive power and not go dead while you have everything connected.
Grab the Surface Dock to take advantage of your Surface Connect port
The Surface Dock provides your Surface Pro 6 with eight extra ports (while using the Surface Connect), allowing you to connect plenty of external accessories and up to two 4K displays at a 30Hz refresh rate. It might be starting to show its age, but it’s still a useful tool for devices that don’t have USB-C or Thunderbolt 3 capabilities.
If you’re looking for an alternative option that turns your Surface Pro into a smaller version of the Surface Studio complete with USB-C, four USB-A 3.0, Ethernet, DisplayPort, and HDMI, have a look at the Kensington SD7000.
Add eight ports to your Surface Pro 6
The Surface Dock connects to your Pro 6 with the Surface Connect port and offers four extra USB-A 3.0, two Mini DisplayPort, Ethernet, and a 3.5 mm audio jack. Connect two external monitors, take advantage of faster-wired internet, and charge your devices while in use.

Tablet or laptop, the choice is yours
The Surface Pro 6 comes with quad-core 8th Gen Intel Core i5 or i7 CPU, improved thermals, and a new black color option. It also includes the proprietary Surface Connect port, which can be used to connect to a Surface Dock.
If you’re invested in your Surface Pro 6 and want to use it for everything, you might find that Kensington’s SD7000 docking station makes a lot of sense despite the rather high asking price. Slide your Pro into the matching stand, connect with Surface Connect, and take advantage of a ton of extra ports, including USB-C, four USB-A 3.1, Ethernet, DisplayPort, HDMI, and a 3.5mm audio jack.
The stand is built from a combination of plastic and metal that matches the Pro, and it’s completely adjustable to work as a standard PC monitor or an angled drawing tablet. It’s a functional, smart design that just works, and if you’d like to turn your Pro into a desktop PC, this is the accessory for you.

It’s pricey, but totally worth it
For those heavily invested in the Surface Pro, the new Kensington SD7000 Dock is a pricey, but outstanding accessory that lets you have one PC instead of two.
