Thank you for viewing. This is the "Genki Dock," a dock that miniaturizes the Nintendo Switch dock. You can output video by connecting the included USB Type-C cable to the Nintendo Switch and the HDMI cable to the TV. Also, since there is a USB Type-A port, you can connect and charge Switch Pro controllers, etc. Please note that the box and HDMI cable are not included. It was working fine before I moved, but after moving and replacing my TV, the connection is recognized on my TV, but no video output is displayed. I am unsure whether the problem is with this product, my TV, or my Switch, and I cannot confirm its operation, so I am selling it as junk. Therefore, I will sell it at a low price.
