The upcoming Surface Dock features a new design which is slimmer than the Surface Dock 2. It has a USB-A and USB-C port to the front and maintains the same I/O selection as the Surface Dock 2 on the back, which includes two USB-C ports, two USB-A ports, a 3.5mm headphone jack, an ethernet port, and a DC connector.
I'm told
this model will be the first Surface Dock to feature Thunderbolt 4 capable USB-C ports, which will provide faster data transfer speeds. Images of the device were spotted in a
recent eBay listing, and I can confirm the device in the photos is the real deal.
Since the new Surface Dock uses USB-C instead of Microsoft’s proprietary connector, it’s likely that the device will work on non-Surface PCs too.
