SUMPK USB4 40Gbps 240W USB-C cable 1 ft 2-pack white

Two-metre reach with 240 W delivery

This 1 ft USB-C to USB-C cable pair supplies up to 240 W at 48 V and 5 A for docks, adapters and other power-hungry devices. Backward compatibility with 140 W, 100 W and 60 W profiles lets the same cords charge any Type-C equipment safely. An integrated E-Marker chip negotiates power contracts to protect connected hardware. The white, male-to-male construction uses copper conductors and 24 pins per connector.

40 Gbps ceiling and protocol bounds

Data moves at up to 40 Gbps, the maximum rate defined by the USB4 40 Gbps tier, so large media libraries transfer in seconds rather than minutes. The same physical link carries 8K video or dual 4K streams, but only when both host and display support the corresponding alternate mode. Thunderbolt 3 and Thunderbolt 4 hosts work, yet actual throughput depends on the controller implementation and cable length limits inherent to the specification.

One-foot length suits tight setups

The 1 ft length keeps desks tidy when linking a laptop to a dock, monitor or drive sitting side by side. It cannot bridge wider gaps such as floor-standing peripherals or cross-room runs, so buyers needing more reach should choose a longer cable. Two cables in the pack provide a spare or a second simultaneous connection for multi-device workflows.
