Techly ICOC USBC-RJ45 — Short Flat USB-C to RJ45 Gigabit FPC Cable
Gigabit EthernetUSB-CFlat 14.4 cmRealtek RTL8153B
The Techly ICOC USBC-RJ45 is a flat USB-C to Gigabit Ethernet adapter cable that adds a wired Gigabit Ethernet port to a laptop, desktop PC, tablet or thin client through its USB-C port. Instead of a box on a cable, it is a flat 14.4 cm flexible-circuit (FPC) cable with an aluminium shell at each end, so it slips into a pocket or laptop sleeve. It is built on the Realtek RTL8153B controller and connects at 10/100/1000 Mbps. It draws its power from the USB port, so there is no separate power supply to carry. A cable connection is the dependable answer when Wi-Fi is weak, crowded or not allowed, when a slim laptop has no network socket, or when backups, large downloads and video calls need a steady, low-latency link.
Compatibility — check before buying:
Check the port: the adapter has a USB-C plug and does not fit USB-A ports; any USB-C data port works, including Thunderbolt 3/4 and USB4 ports. It links at up to 1 Gbps with any standard switch or router port, and Cat5e cable or better is enough. Operating systems listed by Techly: Windows 10/8.1/8, macOS, Chrome OS.

Frequently Asked Questions
Do I need to install a driver?
Supported systems listed by Techly: Windows 10/8.1/8, macOS, Chrome OS. Where the system does not load a driver on its own, install the driver from the Techly support page for this model.
Is it faster than Wi-Fi?
A wired Gigabit link gives up to 1 Gbps with steadier latency than most Wi-Fi connections — that is what video calls, remote desktop and large transfers benefit from. Your internet speed still depends on your connection.
Can I use it on a USB-A port?
No, it has a USB-C plug only. For USB-A computers choose a USB-A version.
Does it work through a dock or USB hub?
Usually yes — it is a standard USB network device. For full speed the hub or dock port must be USB 3.x, and bus-powered hubs should have enough power for all connected devices.
