USB Type C Hub Adapter , Ethlephe USB C Adapter 3.1 with Type C Charging Port , 4K HDMI Output, SD/Micro Card Reader, 1000Mbps Ethernet, 2 USB 3.0 port for MacBook Pro, XPS and More Type-C Devices

So far, this works just like I wanted it to! I just got this last week to use a mouse with my Samsung Galaxy Tab S3. I had purchased a Fintie case with a keyboard to use my tablet like a small laptop. I used this hub to add a mouse, and I was able to leave my laptop at home and be just as productive! I intend to get an HDMI cable so that I can connect my tablet to a tv to play videos for a presentation. Not sure if it will work yet, but I'll update my review when I give it a try.

4k@30hz, don't buy it.

Works like a charm.
