I have a Dell XPS13 Developer Edition that came with such a hub (they call it a dock, but you don't dock to it, you plug it in to the charge port with a USB-C cable). It has DVI, USB, Ethernet, and charges the laptop. It's a nice concept but it does not work well under linux. Most times I plug in the dock, a random port will not work.
