This USB hub is designed to expand the number of USB connections on a computer or laptop. The hub connects via a Micro USB B host port and provides four additional USB A ports for connecting multiple USB devices simultaneously. The hub supports USB 2.0 High-Speed and enables data transfer at speeds up to 480 Mbps. Power is supplied via USB bus power. A USB A to Micro USB B cable is included for connecting to a computer or laptop, which provides both data and power. The hub features individual on/off switches per USB port and LED status indicators, allowing connected devices to be manually activated or deactivated per port.
