Leyu USB4 10 Gigabit Ethernet Network Adapter Compatible With Thunderbolt 3 and Thunderbolt 4 Ports for Desktop Computers Laptops Servers NAS and Soft Routers with 20cm Cable and RJ45 Interface
Leyu USB4 to 10 Gigabit Ethernet Network Adapter for Thunderbolt 3 and 4 Computers

Upgrade your compatible desktop computer, laptop, or server to 10 Gigabit Ethernet speeds with the Leyu USB4 network adapter. This compact device bridges the gap between modern USB4 or Thunderbolt 3/4 interfaces and high-speed wired networking, providing a reliable RJ45 port where one may not be built-in. It is engineered for scenarios demanding high bandwidth, such as video editing from network-attached storage (NAS), fast server backups, or low-latency gaming and professional applications. The adapter automatically negotiates connection speeds from 10Mbps all the way up to its maximum 10Gbps, ensuring compatibility with a wide range of existing network infrastructure. Its design prioritises stable performance within a defined operational temperature window, making it a practical tool for extended use.
Features and Construction

The Leyu adapter is built around a core function: delivering a high-speed, stable Ethernet connection through a single cable. Its construction is focused on reliable data transmission and physical durability for regular use in IT, creative, and home office environments.
Material and Build
The adapter chassis houses the necessary electronics to convert the USB4/Thunderbolt signal to a standard 10GBASE-T Ethernet signal. The build incorporates an RJ45 port for connecting a standard Ethernet cable and a fixed 20cm USB4 cable for connecting to the host computer. The components are selected to maintain functionality across the specified working temperature range of 0°C to +108°C, indicating a design consideration for sustained operation. The storage temperature range is even wider, from -40°C to +110°C, for safe transport and non-operational periods.
Size and Practical Fit
With dimensions of 102.7mm in length, 40.4mm in width, and 25.6mm in height, the adapter is a compact peripheral that won't obstruct nearby ports on a laptop or desktop. The integrated 20cm cable provides a practical length for connecting to a laptop on a desk near a router or switch, or for tidier cable management on a desktop setup. This self-contained design means there are no separate, loose dongles or cables to misplace, keeping the setup simple and portable.
Uses and Placement

This network adapter serves users who need faster and more reliable network connectivity than standard Gigabit Ethernet or Wi-Fi can provide. It is particularly relevant in mixed-interface environments where the fastest port on a computer is USB4 or Thunderbolt.
Event or Professional Use
For professionals working on location, such as videographers transferring large 4K or 8K video files from a camera to a laptop and then to a NAS, the 10G connection can drastically reduce transfer wait times. In IT scenarios, it can provide a temporary high-speed interface for server diagnostics, cloning drives over a network, or connecting a laptop directly to high-speed core network switches for configuration. Its wide operating temperature tolerance supports use in various environments, from data centres to mobile editing suites.
Everyday Home Use
For the home power user, this adapter can connect a high-end laptop to a 10G-capable home router or a multi-gigabit internet connection, maximising download speeds. It is ideal for users with a home server or NAS used for media libraries, where streaming high-bitrate files or performing backups benefits from the increased bandwidth. Gamers seeking the lowest possible latency for online play may also prefer a direct, high-speed wired connection facilitated by this adapter.
Benefits and Buying Value

The value of this adapter lies in its specific compatibility and the tangible upgrade in network performance it enables for supported systems, without requiring internal hardware modifications.
Reuse and Low Maintenance
As a peripheral, the adapter can be moved between different compatible computers as needed, extending the useful networking life of a single device across multiple systems or upgrades. It requires no internal drivers or complex software for basic operation in most modern operating systems, and its solid-state design with no moving parts suggests minimal maintenance beyond careful handling.
Why Choose This Product
This product is a direct solution for users whose computers have a USB4 or Thunderbolt 3/4 port but lack a built-in high-speed Ethernet port. Its key differentiator is its explicit compatibility with these specific high-bandwidth interfaces, which is necessary to achieve the full 10Gbps potential. The inclusion of all necessary cables in the package and its compact, all-in-one design offer a complete, plug-and-play solution for immediate network upgrades, provided the host system meets the interface requirements.
