Instantly upgrade your network connectivity and eliminate weak wireless zones with the high-performance TRENDnet USB 3.0 to Gigabit Ethernet Adapter (Model TU3-ETG). Engineered for remote professionals, competitive gamers, and power users working on ultrabooks, MacBooks, or tablets lacking native network ports, this compact adapter bridges the gap between your machine and high-speed hardwired networks. By utilizing a SuperSpeed USB 3.0 Type-A interface, it guarantees unrestricted access to true gigabit network bandwidth without the data choking typical of older USB 2.0 conversion dongles.
Equipped with a premium 1000BASE-T RJ-45 port, the TU3-ETG handles full-duplex transmission speeds up to 2Gbps to ensure fluid, latency-free video conferencing, massive file backups, and seamless 4K video streaming. The low-profile, featherlight casing features a flexible integrated 12.7cm (5-inch) tail cable that effectively reduces mechanical leverage strain on your computer's USB port. Highly energy-efficient, this bus-powered network adapter incorporates advanced green power-saving technology to reduce operating consumption by up to 70%, preserving your laptop's battery life while maintaining absolute hardware plug-and-play synchronization across modern operating systems and gaming consoles.
