  • 8K 60 Hz or 4K 144 Hz display support for ultra-high-definition viewing
  • 40 Gbps data transfer moves large files in seconds
  • 240 W power delivery with automatic adaptation down to 25 W
  • Thunderbolt 4 and Thunderbolt 3 compatibility across USB-C devices
  • 36 month warranty provides long-term peace of mind

Purpose and compatibility

This three-foot USB4 cable carries 40 Gbps data, up to 240 W power and 8K 60 Hz video. It works with Thunderbolt 3 and Thunderbolt 4 hosts, so laptops, tablets, phones and desktops can share one cable for charging, display and fast file transfer.

Thermals noise and power

The cable itself has no active cooling and makes no noise. Power delivery auto-negotiates at 25 W, 30 W, 60 W, 100 W, 120 W or the full 240 W depending on the charger and device, so heat stays low during normal charging and data sessions.

Sustained load behaviour

Under continuous 40 Gbps transfers or 8K 60 Hz streaming the link remains stable without throttling. Backward compatibility covers 4K 144 Hz, 2K and 1080 P signals, so extended workloads keep full bandwidth and power without drop-outs.

Questions about this item

How do I connect this 3ft Thunderbolt cable for 8K 60Hz video and 240W charging?

Plug each USB-C end into the host and the display or dock; the cable handles 40Gbps data, 8K 60Hz video, and up to 240W power automatically.

Will the 240W charging capability or 40Gbps speed degrade over time?

The cable is passive and has no wear items; performance stays at 240W and 40Gbps unless the connectors are physically damaged.

What is the first limit I hit when running 8K 60Hz and 240W continuously?

The 3ft length is the limiting factor; longer runs would need an active cable to maintain 40Gbps and full power delivery.
