USB4 40Gbps 240W cable for high-power devices

This USB4 cable delivers up to 40Gbps bandwidth and 240W power delivery for demanding laptops, tablets and solid-state drives. It supports 8K video at 60Hz and works with Thunderbolt 3 and 4 hosts. The 3.3FT length suits typical desk setups.

Practical limits of USB4 and Thunderbolt

Full 40Gbps speed requires both host and peripheral to support that rate; 20Gbps USB4 devices will run at their lower ceiling. Video output depends on DisplayPort Alternate Mode support in the source device. The 240W maximum only applies when the charger, cable and device all implement USB PD 3.1 Extended Power Range at 48V/5A.

Installation and common issues

Connect USB-C plug to USB-C port on each end; the cable is reversible and requires no driver. Problems usually arise when a port lacks video-alt mode or negotiates only 20Gbps or lower power profiles. Using a non-EPR charger caps output at 140W or 180W depending on the adapter voltage. Dual 4K displays need two separate cables.
