Your laptop has one USB slot and no Ethernet port. You've been juggling dongles for months. Stop.
The Simplecom CHN420 is one small aluminium block that gives you three SuperSpeed USB 3.0 ports (up to 5Gbps) and a built-in Gigabit Ethernet port (up to 1000Mbps). No external power brick. No driver downloads. Plug it in, done.
The unibody aluminium build won't rattle or crack on your desk. LED indicators show you at a glance whether power and network are live. At 87 × 24 × 17mm, it disappears next to your keyboard.
Works out of the box on Windows 7+, macOS 10.6+, and Chrome OS. If your ultrabook or Chromebook is starving for ports, this is the fix.
