This hub features 3 USB 3.0 ports with plug & play and USB charging functionality – the hub automatically detects if a device that can be charged via USB is connected. The USB 3.0 interface is particularly important when transferring large amounts of data from your memory cards and flash storage devices. The Gigabit Ethernet port allows for easy access to a 10/100/1000 Mbps network, providing you with a fast internet connection without interruptions. The hub is powered via the USB bus. To protect your computer from short circuits in peripheral devices, it includes built-in surge protection. The hub does not require an external power supply and supports a wide range of operating systems from Windows to Mac OS to Linux. The Ethernet network connection can also be used on Android, but it must already be supported by the manufacturer in the Android device. You can check if the Ethernet network connection is supported under Network Settings – Other Networks – Ethernet. The hub is suitable for use with MacBook Pro 2016, MacBook 2015, Chromebook Pixel 2015, Acer Switch Alpha 12, Dell XPS 13, HP EliteBook Folio G1, ASUS UX390UAK, and other devices with a USB-C connector. This connector has many advantages – it is small and symmetrical, allowing for easy connection without having to worry about the orientation of the connector.
