Fervit

Fervit USB4 Cable 20Gbps 140W 8K Female Extension 20cm

SKU CH-M6QK-MGP4C

A 20 cm USB-C male-to-female extension cable delivers 20 Gbps data, 140 W charging and 8K 60 Hz video in a 4.8 mm ultra-flexible sheath

  • Extend USB-C reach by 20 cm in tight spaces
  • Transfer data at up to 20 Gbps for large files
  • Charge laptops at up to 140 W while in use
  • Drive a single 8K display at 60 Hz via DP Alt Mode
  • Ultra-soft 4.8 mm cable routes easily behind desks

Purpose and audience

This USB4 Type-C extension cable adds 20 centimetres of reach between a host port and a peripheral. It suits laptop users who need extra length for docking stations, external drives or monitors without moving the computer. The male-to-female layout keeps the original device connection intact while extending the cable run.

Flexibility and routing

The ultra-soft 4.8 millimetre diameter jacket bends easily in tight spaces behind desks or inside bags. This physical suppleness reduces strain on ports during frequent connect and disconnect cycles. No additional adapters or software are bundled; the cable itself is the only component supplied.

Deciding specification

The cable delivers up to 20 gigabits per second of data throughput and carries up to 140 watts of power at 28 volts and 5 amps. Video output reaches a single 8K display at 60 hertz when the host and monitor both support DP Alternate Mode. Buyers whose devices lack DP Alternate Mode over USB-C will not get a video signal from this cable.

Questions about this item

Does the 4.8 mm diameter cable need any periodic replacement?

The cable is built with an ultra-soft, flexible jacket rated for repeated bending in tight spaces, so no scheduled replacement is required under normal use.

What limits sustained 140 W charging through the 28 V / 5 A path?

The 20 Gbps data lane and 140 W power delivery share the same conductors, so the thermal limit of the 4.8 mm cable assembly is the first constraint during continuous high-power operation.

How warm does the 20 cm extension get when running 8K at 60 Hz all day?

The short 20 cm length and 4.8 mm diameter keep resistance low, so the cable stays close to ambient temperature even during continuous 8K 60 Hz video and 140 W charging.
