  • Charges devices up to 240W with 48V/5A power delivery
  • Transfers data at 40Gbps maximum theoretical speed

5FT USB4 Cable for Thunderbolt 4 devices

This 5FT USB4 cable connects USB-C devices that support Thunderbolt 4, delivering up to 240W of power and 40Gbps data transfer. It suits professionals who need a single cable for charging high-performance laptops and moving large project files quickly. The cable also carries video signals up to 8K at 60Hz for external displays.

240W power delivery with 48V/5A rating

The cable supports the USB Power Delivery 3.1 Extended Power Range, supplying up to 240W at 48V/5A when paired with a compatible charger and device. This single specification decides whether the cable can fast-charge a particular laptop or only provide standard power levels. Buyers whose devices accept less than 240W will still charge safely at the negotiated rate.

Backward compatibility

The cable works with older Thunderbolt 3 ports and USB 3.2, 3.1 and 3.0 hosts, though speeds and power fall back to the limits of those interfaces. This means one cable covers current Thunderbolt 4 gear and legacy USB-C equipment without needing separate leads. It is not for users who require Thunderbolt 5 or USB4 Version 2.0 bandwidth.

Questions about this item

How much power can the 240W rating actually deliver to my laptop?

The cable supports up to 240W at 48V/5A, so it will deliver the maximum power your device and charger negotiate.

What limits the 40Gbps data rate in everyday use?

Both the host and the storage device must support 40Gbps; real-world reads reach 2.8GB/s and writes 2.1GB/s.

Does the 5FT length work with a desk-mounted dock?

At 5FT the cable reaches most desk-mounted docks without strain, and the USB-C to USB-C connectors fit standard ports.
