What this cable does

The CableDeconn USB4 cable carries data, video and power over a single USB-C to USB-C connection. It supports the USB4 40Gbps data rate and delivers up to 100W of power at 20V/5A. The cable handles external displays up to 8K at 60Hz or 4K at 60Hz when the host and monitor both support DisplayPort Alternate Mode.

Who it suits and who it does not

This cable suits users who need full USB4 bandwidth for fast external SSDs, eGPU enclosures or high-resolution monitors. It also suits anyone charging a laptop at 100W while moving large files. Buyers whose devices only support USB 3.2 or Thunderbolt 3 at lower speeds will not see the 40Gbps rate. Buyers who need longer reach than one metre should look at something else.

Behaviour under sustained load

The cable maintains the 40Gbps link during extended transfers provided both ends support the full USB4 rate. Power delivery stays at 100W continuously when the charger and device negotiate 20V/5A. Video output remains stable at 8K 60Hz or 4K 60Hz for long sessions as long as the host and display sustain the required DisplayPort Alternate Mode bandwidth.

Questions about this item

What port must my monitor provide for the 8K@60Hz video output to work?

The monitor needs a USB-C port that supports DisplayPort Alternate Mode; without it the cable cannot pass video.

Will this cable deliver 40Gbps data speeds when I connect it to a Thunderbolt 3 dock?

Yes, the cable is rated for 40Gbps and works with Thunderbolt 3, but the dock and the host must both support that speed to reach it.

How can I confirm the cable is providing 100W charging after I plug it in?

Check the power reading on the connected device or its original charger; it should show up to 20V/5A when the source and device both support 100W.
