The versatility of the USB-C port means that it can simultaneously perform several different functions, including data transfer and power input. Rather than being forced to choose one or another, you can enjoy the superior security and increased data transfer speeds of a wired Ethernet connection, as well as the flexibility of three SuperSpeed USB 3.0 ports for connecting external hard drives, flash drives, and other USB devices, all while charging your laptop's battery. Capable of data transfer speeds up to 5Gbps, this hub is also backwards compatible with USB 2.0 and 1.1 devices. A true plug & play device, no drivers or software installations are required to use this Gigabit adapter or USB ports on a Windows or Mac OS X machine.
