Cable Length 3.3 Feet

  • Charges laptops fully in under an hour with 240W power delivery
  • Transfers large files at up to 80Gbps between compatible devices
  • Drives a single 16K display at 60Hz or dual 8K monitors
  • Works with Thunderbolt 3, 4 and 5 plus USB 3.2, 3.1 and 3.0 devices
  • Compact 3.3 ft length keeps desk setups tidy and portable

Thunderbolt 5 cable for high-power

This 3.3 ft USB C to USB C cable supports Thunderbolt 5 and is backwards compatible with Thunderbolt 3 and 4 as well as USB 3.2, 3.1 and 3.0. It delivers up to 240 W of power at 48 V and 5 A, enabling rapid charging for devices such as MacBook Pro models.

Suits users who need 80 Gbps data rates

The cable reaches 80 Gbps transfer speeds when both host and peripheral support that rate and can drive a single 16K display at 60 Hz or two 8K displays using two cables. Buyers whose hardware tops out at lower Thunderbolt or USB speeds will not see the maximum throughput or resolution.

240 W power delivery at 48 V and 5 A

This single specification determines whether the cable can fully utilise the charging capability of compatible laptops and docks. If the connected power source or device does not support 240 W, the higher charging rate will not be achieved.

Questions about this item

Will the 240W charging capability degrade over time with daily use?

The cable is rated for up to 240W at 48V/5A and maintains this specification as long as the connectors and wiring remain undamaged; no periodic recalibration or replacement schedule is required.

What limits the 80Gbps data rate during prolonged transfers?

Sustained 80Gbps throughput requires both host and device to support that speed; the cable itself does not impose a lower ceiling, so the first limit encountered will be the connected hardware or thermal throttling on the endpoints.

Does the cable get hot or draw extra power when running 16K@60Hz video all day?

The cable is passive and draws no power of its own; heat generation is negligible during 16K@60Hz transmission, and no active cooling or additional power supply is needed for continuous operation.
