Mercury Thunderbolt 4 Dock — Ten-Port Hub
The Razer Mercury Thunderbolt 4 Docking Station consolidates ten ports into a single Thunderbolt 4 link. It targets creators and professionals who need display, network, audio and peripheral expansion from one cable on Windows 10 or macOS 11.1 and later.
Dual 4K or Single 8K Video Headroom
Two 4K 60 Hz monitors run on Intel-based Macs and Windows PCs; M1 Macs support only one 4K 60 Hz output. Four Thunderbolt 4 ports, three USB-A 3.2 Gen 2 ports, Gigabit Ethernet, UHS-II SD reader and 3.5 mm audio handle most workflows; the single upstream connection limits total aggregate bandwidth.
90 W Charging With Quiet Operation
Synchronous power delivery up to 90 W charges the host laptop while driving attached devices. The compact 1.06 by 7.48 by 2.93 inch aluminium enclosure dissipates heat passively, so the unit runs silently under typical office loads. Weighing 338 g, it adds minimal bulk to a desk setup.

Questions about this item
Will this Mercury dock work with my older Thunderbolt 3 laptop and still charge it?
Yes, it is backwards compatible with Thunderbolt 3 Windows PCs and Macs running macOS 11.1 or later, and delivers up to 90 W of power to the host.
How can I confirm the Razer Chroma lighting is active after I connect the dock to my Windows PC?
Open Razer Synapse on Windows; the dock appears as a Chroma device so you can customise colours and effects to verify it is working.
Does the package include a Thunderbolt 4 cable and a power adapter, or must I buy them separately?
The dock ships with its own power supply and a Thunderbolt 4 cable in the box, so no extra purchases are required for basic operation.
