Techly IDATA USB-ETGIGA-3A USB 3.0 to Gigabit Ethernet – 10/100/1000 & RTL8153B

The Techly IDATA USB-ETGIGA-3A is a compact USB 3.0 to RJ45 Gigabit Ethernet adapter that connects to a notebook or computer via a USB Type-A port. It is designed to replace a missing or malfunctioning internal RJ45 Gigabit Ethernet port and requires no external power supply — it draws power from the USB bus.

The adapter uses a Realtek RTL8153B chipset and supports USB 3.0 data transfer up to 5 Gbps on the host interface. Network speeds of 10, 100, and 1000 Mbps are supported. It is compatible with Windows, Linux, and Mac operating systems, and ships with a white housing measuring 72 x 27 x 16.5 mm.
