Universal USB-C Docking Station

The Tripp Lite U442AB-DOCK9 turns a single USB-C or Thunderbolt 3 port into seventeen connections for Windows laptops, Chromebooks or MacBook Pro devices. It is built for professionals who need multiple displays, wired networking and legacy ports from one compact hub. The antibacterial chassis suits shared environments such as schools, medical offices or hot-desk workspaces.

Build Integration

The detachable USB-C cable links the dock to any host that supports DisplayPort Alternate Mode, delivering video, data and up to one hundred watts of pass-through charging simultaneously. Two USB 3.2 Gen 2 Type-C ports, two USB 3.2 Gen 2 Type-A ports, two USB 2.0 Type-A ports and a Quick Charge 3.0 port free up the host’s own sockets for peripherals. Gigabit Ethernet adds a stable wired link where Wi-Fi is unreliable.

Capacity and Headroom

Triple-display output drives two 4K screens at sixty hertz over HDMI or DisplayPort plus a 1080p VGA monitor, covering most multi-monitor workflows. SD 4.0 and microSD 4.0 slots accept high-capacity cards for rapid media ingest. Buyers who require more than three external displays or need Thunderbolt 4 bandwidth will find this dock insufficient.
