4-in-1 USB-C Hub with 100Mbps Ethernet

The GCROWN adapter expands one USB-C port into three USB 3.0 ports and a 100Mbps RJ45 connection. All four ports operate at the same time. It is built for laptops and tablets that lack a wired network jack and need extra USB-A sockets.

Suits USB-C laptops needing wired LAN

Users with only USB-A host ports cannot connect this hub. Devices that require Gigabit Ethernet speeds will not reach that rate through the 100Mbps RJ45 port. Machines without any USB-C or Thunderbolt 3 socket are not compatible.

100Mbps RJ45 port limits wired network speed

The Ethernet interface tops out at 100Mbps, so full Gigabit throughput is not possible. If your workflow depends on 1000Mbps LAN performance, this adapter will be the bottleneck.

Questions about this item

Does the USB-C plug need any driver installation before the 100Mbps RJ45 and three USB 3.0 ports start working?

No driver is required; the hub is plug-and-play on Windows 10, 8.1, 8, Mac OS and Chrome OS, so the Ethernet and all three USB 3.0 ports activate immediately after insertion.

Will the aluminium casing or the RJ45 connector need periodic cleaning or replacement under normal office use?

The aluminium casing and RJ45 port are solid-state with no moving parts, so no scheduled cleaning or replacement is needed; only the USB 3.0 ports may wear after very high insertion cycles.

What throughput ceiling appears first when all four ports run together for long file transfers?

The 100Mbps Ethernet link saturates well before the three USB 3.0 ports reach their 5Gbps limit, making the RJ45 connection the first bottleneck under sustained load.
