What the cable delivers

This USB-C to USB-C cable carries 40 Gbps data and up to 240 W power. It is built for users who need full Thunderbolt 4 bandwidth and the latest Power Delivery ceiling in a single four-foot link. Thunderbolt 3 hosts and legacy USB 3.2, 3.1 and 2.0 devices also work at their rated speeds.

How it fits the desk

The male-to-male ends plug directly into laptops, docks, monitors or high-speed storage without adapters. One cable handles charging, video and data simultaneously, freeing ports that would otherwise need separate power and display leads. DisplayPort Alternate Mode must be supported by the host port for video output.

Behaviour under sustained load

The 240 W rating (48 V at 5 A) is maintained continuously when both charger and device negotiate the full profile. Real-world transfers reach 2.8 GB/s read and 2.1 GB/s write, well below the 40 Gbps ceiling but stable across long sessions. Thermal limits of the connected hardware, not the cable, set the practical ceiling.
