Razer RC21-02280100-R3U1 USB 4 Dock: 14 Ports, Dual 4K 120Hz

The promise of a single-cable desk has been partially fulfilled by Thunderbolt docks for years, but USB 4's 40 Gbps ceiling finally gives that concept enough headroom to be genuinely useful rather than a compromise. The Razer USB 4 Dock runs 14 ports — USB-C, USB-A, HDMI, DisplayPort, Ethernet, SD, and 3.5mm audio — through one USB 4 connection to the host, while simultaneously delivering 100W of power delivery back to the laptop. That bandwidth budget supports dual monitor output at up to 4K 120Hz on the primary display alongside high-speed storage and peripheral I/O without saturating the upstream link the way a USB 3.2 hub would under equivalent load.

The dock is built around an all-metal chassis that keeps a compact footprint on the desk while managing heat passively — relevant when you're running displays, charging, and fast storage transfers simultaneously over extended work sessions. It's Windows and Mac compatible, which matters for teams running mixed environments or for users transitioning between platforms. The included 180W power adapter provides enough overhead for the dock's own operation plus the full 100W delivery to a connected laptop. For creative professionals, developers, or power users who arrive at a desk and want everything — displays, drives, audio, network — live the moment the cable lands, this dock delivers on that workflow with the bandwidth to back it up.
