Your ultrabook has one USB-C port and no ethernet. You need a monitor, a mouse, a keyboard, and a wired network connection before your next video call. Stacking adapters on top of each other is not the answer.
The Simplecom CHN421 solves it in one 87 mm aluminium block. Three SuperSpeed USB-A ports (up to 5 Gbps) for your peripherals, plus a built-in RJ45 Gigabit Ethernet port (1000 Mbps) so you're off Wi-Fi and on a stable line. No external power brick. No drivers to hunt down. Plug it in, LED lights up, done.
Built for the thin-and-light crowd – Chromebooks, MacBooks, Windows ultrabooks that skipped the ethernet port. Aluminium unibody means it sits flat on your desk and doesn't rattle or flex after a year of yanking cables.
Runs on Windows 7 and above (32/64-bit), macOS 10.6+, and Chrome OS. IPv4 and IPv6 supported out of the box.
