USB4 cable for 40Gbps workflows

This 1.5FT USB4 Type-C cable delivers up to 40Gbps bandwidth and 240W charging for professionals who move large datasets or drive high-resolution displays. It suits creators connecting Thunderbolt 4 docks, SSDs or monitors to compatible laptops and tablets. Builders needing longer reach or legacy USB-A connectors should look elsewhere.

Handles 8K 60Hz and 240W PD 3.1

The cable supports 8K at 60Hz or dual 4K outputs when the host and display both allow it, and it negotiates 28V/140W, 36V/180W or 48V/240W power profiles. Data throughput reaches 40Gbps only with USB4 40Gbps devices; 20Gbps USB4 gear runs at its lower ceiling. Older USB 3.2, 3.1 or 2.0 ports fall back to their native speeds.

Thunderbolt 3 and 4 backward compatibility

Backward compatibility with Thunderbolt 3 and 4 means one cable covers current and previous dock, storage and monitor ecosystems without adapters. PD 3.1 EPR support lets it charge 140W laptops and lower-power tablets from the same brick. No software, drivers or extra accessories are bundled.

Questions about this item

Will this cable deliver 40Gbps data rates when I connect it to my older Thunderbolt 3 dock?

The cable is backward compatible with Thunderbolt 3, so it will work, but the 40Gbps speed requires both the host and the dock to support that rate.

How can I verify the cable is actually providing 240W charging to my laptop?

Check the laptop's power meter or battery settings while connected; it should show a charge rate up to 48V/5A when the charger and laptop both support PD 3.1 EPR.

Does the 1.5FT package include a power adapter or do I need to buy one separately?

Only the USB4 Type-C to Type-C cable is in the box; a PD 3.1 charger capable of 240W must be purchased separately.
