I'm selling this because I bought it at the end of last year, but I no longer need it as I've replaced my Mac. This is a docking station that allows for an additional two-screen output via DisplayLink, even on models like M1 and M2 that only support one external output. Of course, it can also be used with later generations of Macs and Windows. The UGREEN Revodok Pro is a set consisting of a USB-C docking station capable of 4K output and 100W power delivery, and a GaN charger 100W. I think it's a pretty good deal. - Brand: UGREEN - Model Name: Revodok Pro - Connectivity: USB-C, HDMI - Output Resolution: 4K - Max Output: 100W - Included: USB-C cable Thank you for looking.
