V.TOP 3 Ports USB 3.0 Network Hub with 10/100/1000 Gigabit Ethernet RJ45 Converter LAN Wired Network Adapter, Support Win 10, Mac OS Sierra 10.12

The V.TOP® CU008 3-Port USB 3.0 Portable Data Hub with 1 Gbps Ethernet Port Network Adapter
turns a single SuperSpeed USB 3.0 host connection port into an RJ45 Gigabit network port as well as three additional USB 3.0 hub ports. On top of Gigabit Ethernet connectivity, the adapter also adds three USB 3.0 hub ports to your system, which allow you to connect external storage or other USB peripherals locally to the host computer.

Backward compatible with USB 2.0 and USB 1.x standards, the Gigabit Adapter/USB 3.0 hub will still support older USB devices and can also be used with an older system that does not have USB 3.0 ports (network speed limited by USB 1.x/2.0 bus), allowing you to mix and match USB 3.0/2.0/1.x devices. For further portability, the adapters can be used with or without the included external power adapter, eliminating the hassle of having to find an available wall outlet.

Applications:
1. Connect a wide variety of peripherals at home/office to a laptop and be able to instantly disconnect them all from a single USB connection
2. Replace a failed integrated network adapter with an external, USB Ethernet connection, instead of having to open a desktop or laptop computer case
