1 ft USB4 cable 40 Gbps

This 0.3 m USB-C to USB-C cable delivers 40 Gbps data transfer and 240 W power delivery. It supports single 8K at 60 Hz, 5K at 60 Hz, 4K at 144 Hz, or dual 4K at 60 Hz. The male-to-male connectors use 24 pins and include an E-Marker chip for intelligent power negotiation. It is compatible with Thunderbolt 3 and Thunderbolt 4 devices.

Thermals noise and power draw

The nylon-braided jacket and aluminium alloy shells dissipate heat during sustained 240 W charging sessions. No active cooling is present, so the cable runs silently. The E-Marker chip regulates current to match the connected device, preventing over-current conditions and keeping power draw stable under load.

Upgrade path and when it matters

This cable replaces slower USB 3.2, 3.1, 3.0 or 2.0 leads that cannot carry 40 Gbps or 240 W. The jump is worth it when you need full Thunderbolt 3 or 4 bandwidth for high-resolution displays or rapid charging of laptops and phones such as iPhone 15 and 16 series. It is not for users who only require basic charging or sub-10 Gbps data rates.

Questions about this item

How do I plug the 1 ft USB-C to USB-C cable in so the E-Marker chip negotiates 240 W charging?

Insert either male connector into the host and the other into the device; the E-Marker chip automatically negotiates PD 240 W, but the host and device must both support USB Power Delivery 240 W for the full rate.

Will the nylon-braided jacket or aluminum alloy shell wear out and need replacement?

The nylon braid and aluminum shell are passive materials with no moving parts; they do not require scheduled replacement unless physical damage such as fraying or bent connectors occurs.

At what point does sustained 40 Gbps throughput hit a thermal or signal limit?

The 0.3 m length keeps signal loss minimal, so the first limit under sustained 40 Gbps use is typically the host or device controller thermal throttle, not the cable itself.
