3.3 ft USB 4.0 Cable for Thunderbolt Workflows

This 3.3 ft USB 4.0 cable delivers 40 Gbps data throughput and 240 W Power Delivery 3.1 charging through a USB Type-C connector. It is built for professionals moving large media libraries between laptops, monitors and tablets that support the full 40 Gbps link. The integrated E-Marker chip negotiates a stable 48 V 5 A supply for rapid power replenishment.

Thermals and Power in Daily Use

The cable handles 240 W charging without requiring active cooling, relying on its internal E-Marker chip to regulate 48 V 5 A delivery safely. During sustained 40 Gbps transfers the sheath remains at a comfortable temperature thanks to compliant conductor sizing. No fan or external power adapter is involved, so acoustic output is zero.

Build Integration and Compatibility

The 3.3 ft length suits desktop docks and portable setups alike, connecting Thunderbolt 4 or 3 hosts, USB 4 devices and legacy USB-C gear down to 10 Gbps. It drives a single 8K display at 60 Hz or 30 Hz, or dual 4K monitors at 60 Hz when the host supports DisplayPort Alternate Mode. Buyers whose ports only offer 10 Gbps USB-C will not see the 40 Gbps rate or 8K video capability.

Questions about this item

How do I connect this 3.3Ft USB 4.0 cable for 40Gbps data and 240W charging?

Plug the USB Type C connectors into both devices; ensure the host and peripheral each support 40Gbps USB 4 and PD 3.1 at 48V 5A so the built-in E-Marker can negotiate the full 240W rate.

What upkeep does the cable need to keep delivering 240W and 40Gbps over time?

Inspect the USB Type C ends for debris or bent pins, keep the 3.3Ft length free of tight bends or crushing, and replace the cable if the E-Marker chip fails to negotiate 48V 5A or 40Gbps link speed.

What is the first limit I will hit when running 8K@60Hz video and 240W charging simultaneously for hours?

The 3.3Ft cable is rated for 40Gbps data and 240W power; sustained thermal load from 48V 5A current and 8K@60Hz DisplayPort Alternate Mode signalling may trigger connector throttling before the spec ceiling is reached.
