UGREEN CM848 USB-C to RJ45 5GbE Ethernet Adapter – Fast and Reliable Wired Networking
Looking for a faster wired network connection for your laptop or desktop? The UGREEN CM848 USB-C to RJ45 5GbE Ethernet Adapter adds a high-speed Ethernet port to compatible devices through USB-C connectivity. Supporting network speeds of up to 5Gbps, it offers greater potential bandwidth than a conventional Gigabit Ethernet adapter when used with compatible network equipment.
Designed for compatible computers and networking setups, this adapter features a USB-C connector, an RJ45 Ethernet port, a Realtek RTL8157 chipset, and an aluminum alloy housing. It is suitable for users who need faster wired connectivity for large file transfers, network storage, office work, and other bandwidth-intensive tasks.
Common Problems with Ordinary Network Connections
- 📶 Unstable Wi-Fi: Wireless connections can be affected by distance, interference, and network congestion.
- 🔌 Missing Ethernet Port: Many modern laptops have limited ports or no built-in RJ45 connection.
- 🐢 Gigabit Network Limitations: A standard 1Gbps Ethernet adapter can restrict the potential speed of a faster network.
- 📁 Slow Large File Transfers: Transferring large files can take longer when the network connection becomes a bottleneck.
- 💻 Limited Connectivity: Users may need a compact adapter to connect a USB-C computer to a wired network.
Smart Solution: UGREEN CM848 5GbE Ethernet Adapter
The UGREEN CM848 USB-C to RJ45 5GbE Ethernet Adapter converts a compatible USB-C port into a wired Ethernet connection supporting speeds of up to 5Gbps. It uses the Realtek RTL8157 chipset and supports automatic negotiation with compatible 5GbE, 2.5GbE, 1GbE, and 100Mbps networks.
Its aluminum alloy housing provides a durable exterior and helps dissipate heat during use. The compact dongle-style design makes it convenient to carry between home, office, and compatible workstations. The adapter is powered through the USB-C connection, so a separate power adapter is generally unnecessary.
For maximum performance, use a compatible USB-C interface, an Ethernet cable suitable for your network, and a router or switch with a 5GbE port. The adapter cannot independently increase your broadband plan’s speed or overcome the limitations of slower network equipment.

Why Choose the UGREEN CM848 5GbE Ethernet Adapter?
The UGREEN CM848 is a practical option for users who need more network bandwidth than a conventional Gigabit Ethernet adapter can offer. Its 5Gbps capability can help remove a 1Gbps adapter limitation when the host interface, network switch, cabling, and other devices support the higher speed.
The Realtek RTL8157 chipset provides multi-speed Ethernet connectivity, while the aluminum alloy housing adds durability and supports heat dissipation. Its USB-C design also makes it convenient for compatible modern computers that have limited physical ports.
Before buying, check your computer’s USB-C specifications and operating-system compatibility. A USB-C connector alone does not guarantee full 5Gbps performance; the host port and network equipment must support the required data rates.
