The OWC Thunderbolt 3 10GbE Ethernet adapter allows for a high-speed, wired connection anywhere you go. The Ethernet adapter is compatible with any Thunderbolt equipped Windows 10 PC (with driver) or Mac running OS 10.13.6 or later. The adapter is fan-less but is housed in a massive aluminum body acting as a heatsink for silent heat dissipation. The OWC Thunderbolt 3 10GbE Ethernet adapter supports IEEE 802.11az meaning that it can run off a low power USB bus meaning lower impact on your battery life. The OWC 10GbE adapter is pretty durable through its strong aluminum body and durable rubber sleeve.
