CableDeconn USB4 cable 1.2 m 40 Gbps 100 W

This USB4 cable connects USB‑C devices such as laptops, tablets and phones to monitors, docks or high‑speed storage. It suits users who need a single cable for video, data and charging without carrying multiple leads. Buyers whose devices lack USB‑C ports or DisplayPort Alternate Mode will not benefit from the video features.

Installation and common issues

The cable plugs directly into any USB‑C port with no driver installation required. Video output only works when the host and display both support DisplayPort Alternate Mode; otherwise the link falls back to data and power only. Forcing the connector upside‑down or using a port limited to USB 2.0 speeds are the most frequent reasons the 40 Gbps rate is not achieved.

Sustained load behaviour

During extended file transfers the cable maintains the 40 Gbps specification as long as both ends and the storage device support that throughput. Continuous 100 W power delivery remains stable provided the charger and device negotiate 20 V at 5 A. Thermal throttling is not observed in normal indoor use.

Questions about this item

How can I confirm the cable is delivering the full 40 Gbps data rate after connecting my SSD?

The cable supports up to 40 Gbps, but actual speed depends on both the host and the SSD supporting that rate; check the transfer speed in your operating system's storage benchmark tool to verify performance.

What comes in the box and do I need to buy a power adapter separately for 100 W charging?

The package contains the 1.2 m USB-C to USB-C cable only; a 100 W 20 V/5 A capable USB-C power adapter is required separately to achieve maximum power delivery.

Which length should I choose if I need to connect a laptop to a monitor at 8K 60 Hz?

The 1.2 m version supports single 8K@60 Hz or 4K@60 Hz video over DP Alternate Mode, provided the monitor's USB-C port also supports video output.
