240W USB4 Cable with Thunderbolt 4 Support

This three-point-three-foot cable delivers up to 240 watts of power and 40 gigabits per second of data. It suits creators and professionals who connect high-performance laptops, external GPUs or fast SSDs. The braided jacket resists daily wear while the reversible USB-C plugs simplify every connection.

Build Integration: Single-Cable Docking and Power

One cable replaces separate charging and data leads, freeing ports on compact laptops and handhelds. It carries 8K video at 60 hertz alongside full-speed data, so a single link drives a monitor, an eGPU enclosure and a high-capacity drive simultaneously. Backward compatibility with 180, 140, 100 and 60 watt profiles means older chargers still work.

Capacity and Headroom: 40 Gbps and 48 Volt Ceiling

The 40 gigabit ceiling handles uncompressed 8K streams and PCIe-level storage traffic without bottleneck. Power delivery tops out at 48 volts and 240 watts, covering the most demanding mobile workstations. Loads above 240 watts or displays beyond 8K at 60 hertz exceed the cable's rated limits.

Questions about this item

How much power can this 3.3 ft cable deliver continuously at 48 V?

The cable supports up to 240 W with PD 3.1 Extended Power Range and is backwards compatible with 180 W, 140 W, 100 W and lower profiles.

Will the braided jacket stay cool and quiet during all-day 40 Gbps transfers?

As a passive cable it has no fan or active cooling; heat depends on the charger and device, and the braided exterior is designed for durability rather than thermal dissipation.

Which charger and device must I already own to reach 240 W over this cable?

You need a PD 3.1 charger rated for 240 W and a device that accepts 48 V at 5 A; the cable is backwards compatible with 140 W, 100 W and lower power sources.
