What this cable does

The Fervit USB4 cable is a 0.5 ft USB-C to USB-C link rated for 80 Gbps data transfer, 240 W charging and 8K@60 Hz video. It carries an E-marker chip that negotiates PD 3.1 power up to 48 V 5 A and falls back to lower USB4 speeds and PD 3.0 or 2.0 profiles.

Who should use it

Users with Thunderbolt 5 or USB4 2.0 hosts who need maximum bandwidth and power in the shortest possible run will benefit. Buyers whose devices only support USB 3.2 or earlier, or whose USB-C ports lack DisplayPort Alt Mode, will not gain the advertised video or speed advantages.

The deciding specification

The single figure that determines suitability is the 80 Gbps USB4 2.0 rating; if the host and peripheral both support that speed the cable delivers full performance, otherwise it operates at the lowest common denominator.
