A 4-in-1 USB-C hub adding three USB 3.0 ports and a 1000Mbps RJ45 Gigabit Ethernet port with plug-and-play driver-free operation
This USB-C hub adds three USB 3.0 ports and a Gigabit RJ45 Ethernet jack to laptops and tablets that lack built-in wired networking. All four ports operate simultaneously so you can attach storage, peripherals and a network cable at once. It suits mobile professionals and students who need reliable wired internet and extra USB connections without carrying multiple dongles. The aluminium housing resists everyday wear in a bag or on a desk.
The adapter draws power directly from the host USB-C port and has no moving parts, so it runs silently and stays cool during normal office tasks. A green LED shows power status while a blinking indicator confirms active data transfer on the network link. No fan or heatsink is required for typical web browsing, video calls or file sync workloads. The aluminium shell helps dissipate the small amount of heat generated by the controller.
Under continuous heavy traffic the Gigabit Ethernet port maintains up to 1000 Mbps provided a CAT6 or better cable is used, with automatic fallback to 100 Mbps or 10 Mbps on older cabling. The three USB 3.0 ports share the upstream bandwidth, so simultaneous large file copies and network streams will divide the available throughput. The plug-and-play design requires no driver installation on Windows 10, 8.1, macOS, Linux, Chrome OS or Surface devices.

Plug the USB-C connector into the host device; the hub is plug-and-play with no driver installation required. The step often missed is using a CAT6 or higher Ethernet cable to achieve the 1000Mbps gigabit speed, as lower category cables will limit the connection to 100Mbps or 10Mbps.
The aluminum shell and shielded USB 3.0 ports are built for durability with no user-serviceable parts inside. Maintenance is limited to keeping the RJ45 port and USB connectors free of dust; if the Ethernet cable or USB-C host cable becomes damaged, replace the cable rather than the hub itself.
The combined bandwidth of the single USB 3.0 upstream link caps total throughput across the three USB 3.0 ports and the gigabit Ethernet port at 5 Gbps, so simultaneous high-speed transfers on multiple ports will hit that shared bottleneck before any individual 1000Mbps port limit is reached.
