Cable purpose and audience

This 0.5 metre USB-C to USB-C cable carries Thunderbolt 4 and USB4 signals at up to 40 Gbps. It is built for users who need a short, high-speed link between a laptop and an 8K monitor or fast storage device. The connectors are male on both ends and the cable supports 240 W power delivery.

Who it suits and who it does not

It suits owners of Thunderbolt 4 or USB4 laptops such as recent MacBook Pro, Dell XPS or Chromebook models that require 8K at 60 Hz or 4K at 144 Hz video output. Buyers whose monitors lack DisplayPort Alternate Mode on their USB-C port will not get a video signal. Users needing a longer reach should consider a different length.

What the bundle changes

The package contains only the cable itself. No adapters, docks or software are included. Full 40 Gbps data rates and 240 W charging require both the host and the peripheral to support those specifications, and a matching power adapter for the highest wattage.
