Best Usb Ethernet Adapter (2026): 5 Adapters Compared

BENFEI lists this compact USB A/C to Ethernet adapter as adding a standard RJ45 port to an Ultrabook, notebook or MacBook Air for file transfers, video calls, gaming and streaming. A built-in IC chip bridges the RJ45 cable and the USB A/C device, with driver-free installation on Chrome, Mac and Windows. It supports 10/100/1000Mbps over USB A/C's 5Gbps bus, with Wake-on-LAN, duplex Ethernet, crossover detection, backpressure routing, Auto MDIX and LEDs. USB powered with no external power required, backward compatible with USB 2.0/1.1. Compatibility covers Windows 11/10/8.1/8/7/Vista/XP, Mac OSX 10.6/10.7/10.8/10.9/10.10/10.11/10.12, Linux kernel 3.x/2.6, Android and Chrome OS, with IEEE 802.3, 802.3u, 802.3ab and 802.3az Energy Efficient Ethernet. The listing states an 18-month warranty. One oddity: the spec table lists 0.39 in for length, width and height alike and a 1 g item weight, figures that read like placeholders, so judge size from the compact design instead.

Who it's for: someone with both USB-A and USB-C devices who wants one adapter for a desk and a bag. Who should skip it: anyone who needs Nintendo Switch support, or anyone on Windows RT.
