The Simplecom CHN420 is a sleek and durable black aluminium USB hub designed to expand your laptop or PC connectivity with ease. It converts a single SuperSpeed USB 3.2 Gen1 port (formerly USB 3.0) into three USB-A ports and adds a built-in Gigabit Ethernet RJ45 port, ideal for devices lacking an Ethernet port. Featuring transfer speeds up to 5 Gbps on USB ports and up to 1000 Mbps on the Ethernet port, it enables fast data transfers and seamless wired network connectivity.

This compact hub (87 x 24 x 17 mm) boasts an aluminium unibody construction for premium durability and includes LED indicators for power and network status. It is fully USB bus-powered—no external power adapter required—with a low working current (<300 mA), making it perfectly portable.

Compatible with Windows 7 and above (32/64-bit), macOS 10.6 and later, and Chrome OS, it supports plug-and-play operation for immediate use. The hub is ideal for Chromebooks, ultrabooks, and laptops with limited USB ports or no Ethernet jack.
