Fervit USB4 cable 40Gbps 240W 8K 100cm

SKU CH-CFBQ-05XCX

USB4 cable delivers 40 Gbps data, 240 W charging and 8K 30 Hz video over 100 cm

  • Charges devices at up to 240W via USB Power Delivery
  • Transfers data at up to 40Gbps with USB4
  • Drives a single 8K display at 30Hz or 5K at 60Hz via DP Alt Mode
  • Works with USB-C laptops including Mac Pro 2018, 2019, 2020 and XPS models
  • Backward compatible with USB 3.1 devices and docking stations

What this cable does

The Fervit USB4 cable carries data at up to 40 Gbps and delivers up to 240 W of power at 28 V 5 A or 100 W at 20 V 5 A. It drives a single external display at 8K 30 Hz, 5K 60 Hz or 4K 60 Hz when the monitor’s USB‑C port supports DisplayPort Alternate Mode. The cable is 100 cm long and is backward compatible with USB 3.1.

Who it suits and who should look elsewhere

It suits users who need maximum USB4 bandwidth, high‑power charging for laptops and 8K video from a single cable. Buyers whose monitors lack DisplayPort Alternate Mode will not get a video signal. Anyone who requires longer reach than 100 cm should consider a different length.

The specification that decides fit

The 40 Gbps USB4 data rate is the deciding factor; if your host and device both support USB4 you will achieve the full speed, otherwise the connection falls back to the lowest common standard.

Questions about this item

How much heat should I expect from the cable when delivering 240 W continuously?

The cable is rated for 28 V at 5 A or 20 V at 5 A, so it handles the full 240 W without active cooling; normal warmth is expected during sustained loads.

My monitor only has HDMI and DisplayPort — can I still use this cable?

Video requires the monitor’s USB-C port to support DP Alternate Mode; without that the cable will carry power and data but no display signal.

Will a laptop with only USB 3.1 ports still get 40 Gbps speeds?

The cable is backward compatible with USB 3.1, but the 40 Gbps rate is only available when both host and device support USB4; otherwise speeds fall to the port’s limit.
