USB4 cable for 40Gbps and 240W

This USB4 Gen 3x2 cable carries up to 40Gbps of bi-directional data and delivers 240W of power over a single USB-C to USB-C link. It supports 8K resolution at 60Hz or dual 4K video output and works with Thunderbolt 3 and 4 hosts, docks and eGPU enclosures. The 1.5FT length keeps the connection short for desktop setups.

Suited for high-power laptops

Creators driving an 8K display, users charging a 140W-class laptop at full speed, and anyone moving large datasets between USB4 Gen 3x2 devices will use the full 40Gbps and 240W capability. Buyers whose devices only support lower USB generations or power profiles will not gain the rated throughput or wattage from this cable.

The deciding spec is USB4 Gen 3x2 at 40Gbps

If both host and peripheral are USB4 Gen 3x2 certified, the cable delivers its maximum 40Gbps data rate and 240W extended power range. With USB4 Gen 2x2, Thunderbolt 3 or USB 3.2 devices the link falls back to their native speeds and power limits.

Questions about this item

Does the cable get warm or draw extra power when running 240 W charging continuously?

The cable supports USB4 Gen 3x2 at 40 Gbps and PD 3.1 up to 240 W at 48 V, so it handles full extended power range loads without needing active cooling.

What charger and device do I need to actually deliver 240 W through this cable?

A USB PD 3.1 extended power range charger rated at 240 W and a device that negotiates 240 W are required; the cable is backwards compatible with 180 W, 140 W, 100 W and lower profiles.

Will this cable work with my older USB-C laptop that only supports 100 W charging and 10 Gbps data?

Yes, it is backwards compatible with PD 3.0, PD 2.0, QC 4.0/3.0, AFC, SCP and FCP, so it will charge at up to 100 W and transfer data at the host's maximum speed.
