Multiport USB-C docking station

The Tripp Lite U442-DOCK1-B converts a single USB-C or Thunderbolt 3 port into a full workstation hub. It adds HDMI, VGA, Mini DisplayPort, three USB 3.0 Type-A ports, Gigabit Ethernet, SD and microSD card slots, a 3.5 mm audio jack and a USB-C power-delivery input. Plug-and-play operation requires no driver installation.

Upgrade from basic adapters

Replaces single-function dongles that only provide one video output or a lone USB port. The jump is worth it when you need simultaneous 4K video at 30 Hz, wired networking and multiple peripherals through one cable. Supports USB DisplayPort Alternate Mode for audio and video transmission.

Suits mobile professionals and hot-desk users

Ideal for Chromebook, MacBook, smartphone or PC owners who move between desks and need a single-cable connection to monitors, network and accessories. Not for buyers who require 4K at 60 Hz or higher refresh rates, or those needing Thunderbolt 4 certified bandwidth.

Questions about this item

What cable length and connector does the dock need to reach my laptop?

The dock connects through a built-in USB-C male plug, so no separate cable is required.

What is the most common mistake when setting up the dock for the first time?

Users often forget that video output requires a host port with USB DisplayPort Alternate Mode support.

Which ports on the dock may need replacement cables over time?

The HDMI, VGA, Mini DisplayPort, USB 3.0 Type-A, RJ45, 3.5 mm audio, SD and Micro SD ports all use standard cables that can be swapped if they wear out.
