● This is a small USB hub equipped with 1 USB 3.0 port and 2 USB 2.0 ports. ● The USB 3.0 port supports high-speed data transfer (5Gbps) [standard value]. ● It is a bus-powered type that does not require AC power. ● Compatible with Windows 7 and later, Android 5.0 and later, and Linux. I purchased this to use in my car, but it was not compatible with my car, so I am selling it. It is a beautiful item that has only been plugged in once. The items in the photos are all that are included. Shipping is planned via Yu-Packet.
