Today, many laptops pursue a thin design – while desktops have ample space for USB ports, laptops must fit in a keyboard, touchpad, and other things surrounding the USB port with little space for expansion slots. To address this, Opro9 has created a USB-C to USB3.0 hub with external Gigabit network assembly and a USB 3.0 interface. It makes the user experience more convenient by allowing one to use up to three USB devices at the same time. It also supports the RJ45 gigabit Ethernet network with transmission speeds 10 / 100 / 1000 Mbps. It perfectly solves the problem of insufficient external expansion slots, expanding the laptop’s functionality and increasing productivity.
