Cable standard and speed

This is a USB4 Gen 3x2 cable with a USB-C male-to-male connector. It carries data at up to 40Gbps and delivers up to 240W of power under the PD 3.1 specification. The cable is built with a braided jacket and includes an E-Marker chip for safe high-wattage negotiation.

Ideal uses and limits

It suits owners of Thunderbolt 3 or 4 laptops, docking stations and high-speed SSD enclosures who need full 40Gbps throughput and 240W charging. It also drives one 8K@60Hz display or two 4K displays from a single port. Buyers whose devices only support USB 3.2 or lower will not reach the rated data rate or power level.

Deciding specification

The single figure that determines suitability is the 40Gbps data rating combined with 240W PD 3.1 power delivery. If the host, charger or peripheral does not support both USB4 Gen 3x2 and PD 3.1 at 48V/5A, the cable will fall back to lower speeds and wattages.
