Overview

The Razer Thunderbolt 4 Cable (RC21-01860200-R3M1) is a high-performance connectivity solution designed for users who demand maximum throughput from a single cable. Supporting data transfer speeds up to 40 gigabits per second, it can drive external NVMe storage arrays, Thunderbolt docks, and eGPU enclosures at the full bandwidth the Thunderbolt 4 standard allows. It simultaneously supports display output at resolutions up to 8K, making it capable of feeding high-resolution monitors through compatible docking stations or direct display connections.

In addition to data and video, the cable delivers up to 100 watts of USB Power Delivery charging, meaning a single connection can power a laptop while transferring data and driving a display. At 0.8 meters (2.5 feet), the cable is intentionally compact — ideal for clean desk setups where a dock or external drive sits next to the host machine. Backwards compatibility with Thunderbolt 3 devices and support for both Windows and Mac systems ensure broad usability across existing hardware, making this a versatile addition to any Thunderbolt-equipped workstation.
