Fervit USB4 cable 30 cm lanyard

This new Fervit USB4 cable is a 30 cm USB C to USB C lead that doubles as a wrist lanyard for phones. It targets users who want a short, durable tether that prevents drops while delivering full USB4 Ver 2.0 performance. The FPC internal construction adds flexibility and toughness compared with standard cables.

Sustained 80 Gbps bandwidth and 240 W charging

The cable maintains up to 80 Gbps data rates under continuous transfer workloads thanks to its FPC design and built-in E-marker chip. PD 3.1 support keeps 240 W power delivery stable during long charging sessions, with backward compatibility to 140 W, 100 W and 60 W profiles. Heat and signal integrity are managed for extended use.

DP Alt Mode required for 8K 60 Hz video

Video output up to 8K at 60 Hz or dual 4K at 60 Hz only works when the host USB C port supports DP Alt Mode. Without that feature the cable still handles data and charging but cannot drive displays. Check your device specifications before relying on the video function.

Questions about this item

Does the 240 W PD 3.1 charging generate noticeable heat when the cable runs all day?

The built-in E-marker chip manages PD 3.1 up to 240 W and negotiates lower profiles such as 140 W, 100 W or 60 W, keeping thermals in check during extended use.

What must my device already have for the 80 Gbps data rate to work?

Your host and peripheral need USB4 Version 2.0 or Thunderbolt 5 ports that support the 80 Gbps signalling rate.

Will the cable still carry video and data if I plug it into a Thunderbolt 3 dock?

Yes, it is backward compatible with Thunderbolt 3 and 4, so video up to 8K 60 Hz and data at 40 Gbps will function normally.
