Mercury 11-Port Docking Station

The Razer Mercury USB-C Dock adds eleven ports to a single USB-C connection on Windows 10 or later PCs and Macs running macOS 10.13 or later. It suits professionals who need video, data, networking and card-reader access from one compact hub.

Thermals, noise and power delivery

The dock accepts up to 100 W of USB-C power input and passes 85 W downstream to charge the host laptop while driving peripherals. No active cooling is present, so operation remains silent under normal multi-port workloads.

Bundled connectivity changes

A single HDMI output drives one external display at 4K 60 Hz. Two USB-A 3.2 Gen 2 ports and one USB-C 3.2 port run at 10 Gbps for fast storage, while two USB-A 2.0 ports handle legacy devices. Gigabit Ethernet adds wired networking, a 3.5 mm jack handles audio, and a MicroSD slot reads memory cards directly.

Questions about this item

How do I connect the Mercury dock so the laptop charges at 85 W while using the 4K 60 Hz HDMI output?

Use the supplied USB-C cable to link the dock's USB-C Input port to the laptop's USB-C port that supports 100 W PD IN; the dock then delivers 85 W PD to the laptop and drives the HDMI display at 4K 60 Hz simultaneously.

Which port on the Mercury dock will need a cable replacement first with daily plugging and unplugging?

The USB-C Input port sees the most insertions because it carries both 100 W PD IN and all 10 Gbps data for the 11-port hub; keep a spare USB-C 3.2 cable rated for 100 W handy.

What thermal limit appears first when every port on the Mercury dock runs at full speed for hours?

The 85 W power-delivery circuitry hits its thermal ceiling before the 10 Gbps USB-C or Gigabit Ethernet controllers, so sustained maximum charging throttles first.
