1.8 m USB-C cable with 240 W charging

This 1.8 metre USB-C to USB-C cable delivers up to 20 Gbps data transfer, 8K video at 30 Hz or 4K at 120 Hz, and 240 W Power Delivery. It suits professionals connecting laptops to high-resolution monitors or fast external storage. The cable is backward compatible with earlier USB-C devices and works with CarPlay and Android Auto systems.

Ideal for single-cable docking.

Creators and mobile workers who need one cable for video, data and charging will benefit from the combined 20 Gbps bandwidth and 240 W power. Buyers who require cable lengths beyond 1.8 m for permanent desk installations should consider other options, as this length is fixed. The passive design also limits maximum reach compared with active or optical alternatives.

20 Gbps USB 3.2 Gen 2x2 bandwidth decides fit

The single specification that determines suitability is the 20 Gbps data rate provided by USB 3.2 Gen 2x2. If your workflow moves large video project files or drives high-refresh 4K displays, this bandwidth matches the requirement. Systems limited to 10 Gbps or 5 Gbps ports will not utilise the full speed, though the cable remains functional at lower rates.

Questions about this item

Does the cable ship with any adapters or power bricks, or do I need to supply my own charger?

Only the USB-C to USB-C cable is included; a USB-C power adapter or charger must be provided separately to deliver up to 240 W.

Should I choose a different length or speed rating for 8K at 30 Hz versus 4K at 120 Hz?

This 1.8 m cable handles both 8K at 30 Hz and 4K at 120 Hz at its rated 20 Gbps, so no alternative version is required for either resolution.

Will the 240 W rating actually charge my laptop at full speed, or is that a theoretical maximum?

The cable supports up to 240 W Power Delivery, so it will pass the full charge rate provided your laptop, charger and port all support that level.
