What this cable does and who uses it
The Fervit USB4 extension cable adds 20 cm of reach between a USB-C host and a USB-C peripheral while carrying data, video and power. It suits laptop owners who need a little extra length for a dock, monitor or external drive without leaving the desk.
Practical limits of the USB4 connection
The link tops out at 20 Gbps and requires the host port to support DisplayPort Alternate Mode for any video output. Without that mode the cable still moves data and power, but no picture reaches the display. Maximum resolution is a single 8K panel at 60 Hz, dropping to 5K or 4K at the same refresh rate if the display or host cannot handle 8K.
Installing the extension and common issues
Plug the male end into the computer and the female end into the device; no driver is needed. The 4.8 mm jacket is ultra-soft, so it routes easily behind monitors or through tight grommets. The only frequent problem is attempting video on a port that lacks Alternate Mode — check the host specification before assuming a picture will appear.

Questions about this item
What does the 20Gbps rating mean for real-world file transfers?
The cable supports USB4 at up to 20Gbps, so large project folders or game libraries move roughly twice as fast as a 10Gbps link, provided both host and device also run at USB4 speeds.
Can the 140W power figure actually charge a laptop while I use it?
Yes — the cable carries up to 140W (28V/5A) or 100W (20V/5A), so most USB-C laptops charge at full speed even under load, assuming the charger and laptop both support that profile.
Will the 8K@60Hz claim work with my monitor?
The cable can carry an 8K 60Hz signal, but the monitor’s USB-C port must support DP Alternate Mode for video; without that mode the display will not receive a picture.
