Thank you for viewing. This is a mini dock for the Nintendo Switch. It has ports for a charging cable and HDMI, allowing you to connect it to a TV and play. You can also play in handheld mode while it's docked. Pressing the button on the bottom right while in TV mode switches the screen to handheld mode. It also has a LAN port, so wired internet connection is possible. Thank you for your consideration. m(_ _)m
