Description

The TP-Link UE300C adapter transforms a USB-C port into a full Gigabit Ethernet port (RJ-45), offering stable high-speed wired network access for devices that otherwise rely solely on Wi-Fi. Especially useful for laptops, tablets, ultrabooks, and hybrids whose wireless connectivity might be inconsistent or limited.

Equipped with a USB 3.0 Type-C interface (SuperSpeed, 5 Gbps) and using the trusted Realtek RTL8153 chipset, the UE300C provides up to 1000 Mbps Ethernet throughput. It’s fully plug-and-play on modern Windows (10/11), macOS (10.9+), Chrome OS, and Linux distributions. Older systems (Windows 7/8, macOS before 10.9) may require driver installation.

Design-wise, it features a foldable, portable form that makes it easy to carry alongside a laptop. The adapter is lightweight (≈ 20 grams) and compact (approx. 71 × 26 × 16.2 mm), yet durable. LED indicators show link/activity status, helping troubleshoot connectivity at a glance. Environmental tolerances are standard: 0-40 °C operating temperature, -40-70 °C for storage, with non-condensing humidity. Certifications include CE, FCC, RoHS.
