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. USB-C Power Port: The USB-C charging port allows you to connect your original USB-C charger, so you can charge your laptop's battery rather than draining it, while using this adapter. 3-Port USB Hub: Add three USB 3.0 Type-A ports, each capable of delivering data speeds up to 5Gbps, for connecting SuperSpeed external peripherals and charging mobile devices. Portable: Small and portable, you can easily slip this adapter into your laptop case and have it ready for use wherever and whenever the need arises.
