USB-C connection, USB 3.0 compatible card reader, and USB HUB with 3 ports. I have confirmed the connection and output in my home environment, but I cannot provide support if it does not work for the buyer (returns are not accepted due to reasons such as incompatibility with OS versions or devices). Please check the photos for details. When packing and shipping, I will wipe the exterior as cleanly as possible and pack and ship using a method with a proven track record of safe transaction completion. - Type: Card Reader - Number of ports: 3 - USB Type: USB 3.0 - Connection terminal: USB-C
