What this cable does

The Fervit USB4 extension cable adds 50 cm of reach between a host port and a USB-C device while preserving 20 Gbps data throughput, 100 W power delivery, and single-display output up to 8K at 60 Hz or 5K at 60 Hz. Its flat FPC construction keeps the cable slim and flexible for tight routing.

Who it suits and who it does not

It suits users who need extra length for a USB-C monitor, docking station, or external drive and whose displays support DP Alternate Mode for video. Buyers whose monitors lack DP Alternate Mode or who require longer reach than 50 cm should look elsewhere.

Specification that decides fit

The cable delivers a maximum 20 Gbps data rate under the USB 4.0 standard, so it will only meet expectations when both the host port and the peripheral operate at that speed.

Questions about this item

What port must my laptop provide for this cable to deliver 8K video?

Your laptop needs a USB4 or USB-C port that supports DisplayPort Alternate Mode to drive 8K at 60 Hz through this cable.

Will my existing USB 3.2 Gen 2 dock still reach 20 Gbps when connected through this 50 cm extension?

No, the dock will run at its own 10 Gbps limit; the cable supports up to 20 Gbps but cannot raise the dock's speed.

How can I confirm the cable is delivering 100 W to my laptop?

Check the laptop's power indicator or OS battery menu — it should show charging at 20 V / 5 A when the source and device both support 100 W PD.
