USB4 Docking Station with 134.40 W Charging
This USB4 docking station expands a laptop into a multi-display workstation using a single USB-C host port. It delivers up to 134.40 W of power to keep the host notebook charged while driving peripherals and network connections. The dock supports video output to two displays simultaneously for extended desktop configurations. It is designed for MacBook and Windows laptops equipped with USB4 or Thunderbolt 4 ports.
For Creative Professionals Needing Dual
Filmmakers, editors, designers and multitaskers who require two simultaneous 4K or 8K monitors will benefit from the dual DisplayPort and USB-C video outputs. The 2.5 Gbps Ethernet port adds stable wired networking for large file transfers. Users whose laptops lack USB4 or Thunderbolt 4 host ports cannot use the full 40 Gbps bandwidth or video features. Buyers needing more than two external displays should look at alternative solutions.
40 Gbps USB4 Host Bandwidth Decides Compatibility
The single USB-C host connection provides up to 40 Gbps data throughput, which determines whether the dock can drive 8K at 30 Hz or dual 4K at 60 Hz and 144 Hz. This bandwidth also governs the speed of attached USB peripherals and the 2.5G Ethernet adapter. If the host port only supports lower USB or Thunderbolt specifications, maximum resolutions and data rates will not be achieved. Verify the laptop port specification before purchase.

Questions about this item
How much power does the 134.40 W charging capability deliver to my laptop while the dock drives two 4K displays at 60 Hz?
The dock supplies up to 134.40 W of power to the host laptop, keeping it charged even when both video outputs are running at 4K 60 Hz and peripherals are connected.
What host port must my laptop provide for the U442-DOCK25 to deliver 40 Gbps data and dual-display video?
Your laptop needs a USB4 or Thunderbolt 4 USB-C port; the dock's host connection relies on that interface for 40 Gbps throughput and 8K or dual 4K video.
Will the dock's 2.5G Ethernet and USB ports work through an older USB-C laptop port that only supports USB 3.2 Gen 2?
The dock requires a USB4 or Thunderbolt 4 host port; on a USB 3.2 Gen 2 port the 40 Gbps bandwidth, dual-display video and full 134.40 W charging will not be available.
