10GbE Performance & USB-C Requirements: Upgrade to fast wired networking with this USB C to 10Gb Ethernet adapter, supporting 10G/5G/2.5G/1G/100M auto-negotiation for broad compatibility. Great for NAS access, large backups, content workflows, and low-latency gaming. Note: 10GbE is the theoretical link rate; real-world Windows throughput is typically ~7Gbps depending on setup. For best results, use a USB 3.2 Gen 2x2 (20Gbps) USB-C port or higher.
Real-World macOS Speed: Compatible with Thunderbolt 3/4/5 and USB4 ports. On Macs, macOS may report a 5Gb link rate, while typical real-world throughput is ~5Gbps depending on the Mac model, network equipment, cabling, and test method. We continuously validate macOS performance and publish the latest notes and updates on our support page.
Stable Performance with Advanced Chipset: Powered by the Realtek RTL8159 USB 10G controller for efficient power use and minimal heat in typical operation. Designed to address the heat concerns common with some 10GbE adapters, this 10Gb Ethernet to USB C adapter delivers cool and reliable performance in a compact design.
Premium & Durable Design: Built to last with a rugged aluminum housing plus integrated thermal silicone and a heat sink to help dissipate heat and withstand daily wear, scuffs, and impacts. The braided USB-C pigtail cable adds strength and flexibility to help prevent fraying and reduce port strain—ideal for travel kits, mobile workstations, and tight dock setups.
Easy Setup & Wide Compatibility: Plug-and-play on the latest macOS and Windows. Some older OS releases may limit performance; if speed is reduced on Windows or certain Linux kernels, install the latest Realtek RTL8159 USB 10G driver (macOS typically needs no manual driver—keep macOS updated). Works with USB-C, USB4, and Thunderbolt 5/4/3 devices including MacBook, iMac, Dell XPS, Surface, iPad Pro, and more. Not for Android / Xbox One S.
