Cable for Thunderbolt 4 workflows

This 0.72 m cable connects Thunderbolt 4, Thunderbolt 3, USB-C and USB4 hosts to docks, displays and storage. It is built for users who need certified 40 Gb/s data and 100 W power delivery in a single short run. The Lightning to USB C connector fits compatible tablets and laptops directly.

Sustained certified throughput

Thunderbolt certification guarantees the cable maintains 40 Gb/s transfer rates and 100 W charging under continuous load, not only in brief bursts. Lab testing confirms stable operation for dual 4K or single 8K video streams while delivering full power to attached docks or adapters. Performance does not degrade during extended sessions.

Lightning to USB C connector constraint

The fixed Lightning to USB C ends mean the cable only suits devices equipped with that exact port pairing. Buyers whose gear uses USB C on both sides or a different connector cannot use this cable. No adapter is included in the package.
