What this cable delivers

This USB4 cable carries 40 Gbps bandwidth and 240 W power delivery over a 3.3 ft braided USB‑C to USB‑C link. It supports 8K 60 Hz video, dual 4K 60 Hz displays and clamshell mode for notebooks. The cable works with Thunderbolt 4, PD 3.1, QC 4.0 and legacy USB standards.

Sustained throughput and thermals

At full 40 Gbps the cable moves roughly 14 hours of HD video or 25 000 photos per minute. The 48 V 5 A rating handles continuous 240 W charging without throttling. Backwards compatibility keeps 180 W, 140 W and 100 W loads stable. Actual data rate depends on the host port generation.

Check your ports and charger

You need a USB4 Gen 3×2 or Thunderbolt 4 port to reach 40 Gbps and 8K 60 Hz. A 240 W EPR PD 3.1 charger is required for the maximum 240 W load. Lower‑power chargers will fall back to 180 W, 140 W or 100 W. Ensure both host and device support the desired video mode.

Questions about this item

Does the cable get warm when delivering 240 W continuously?

The cable is rated for up to 240 W at 48 V and 5 A, so it handles full EPR loads without overheating under normal use.

What charger and device do I need to reach 240 W charging?

You need a USB-C charger that supports PD 3.1 Extended Power Range at 240 W and a device that can accept 240 W over USB-C.

Will this cable work with a Thunderbolt 3 dock that only runs at 20 Gbps?

Yes, the cable is backward compatible and will operate at the dock's 20 Gbps limit while still delivering up to 240 W power.
