A 6.6FT USB-C cable with aluminium connectors and braided jacket

BFKK

BFKK 6.6FT Thunderbolt Cable 240W 40Gbps 8K/6K@60Hz

SKU CH-WRXX-6XTSY

A 6.6 ft Thunderbolt cable delivering 240 W charging, 40 Gbps data and 8K video at 60 Hz

Length 6.6 ft.

  • Charges up to 240 W with PD 3.1
  • Transfers data at 40 Gbps theoretical speed
  • Drives 8K or 6K displays at 60 Hz
  • Works with Thunderbolt 4 and older USB standards
  • Withstands over 10,000 bends and plug cycles

Cable purpose and audience

This six point six foot USB4 cable carries Thunderbolt 4 signals at up to forty gigabits per second and delivers up to two hundred forty watts of power. It suits anyone who needs a single lead for high-resolution video, rapid data movement and heavy-duty charging across laptops, tablets, phones and docking stations.

Bundled capabilities

The lead supports 8K or 6K video at sixty hertz on one display or dual 4K monitors when two cables are used. Power Delivery 3.1, PPS and QC 4.0 let it negotiate the full two hundred forty watts with compatible chargers, while backward compatibility covers USB 2.0, USB 3.2 and Thunderbolt 3 hosts without extra adapters.

Compatibility checks

Verify that your host, charger and display all support USB4 or Thunderbolt 4 to reach the rated forty gigabits per second and two hundred forty watts. Actual transfer speeds will fall to the lowest common specification in the chain, so confirm each device’s rated throughput before relying on peak performance.

Questions about this item

Will the connectors or cable jacket need replacement after repeated bending?

The cable has passed more than 10,000 bend and plug tests, and the aluminium shell is built for durability, so no regular connector or jacket replacement is expected.

What limits the 40 Gbps transfer rate during long sessions?

The practical ceiling is the host and device capability; real-world throughput reaches 2.8 GB/s read and 2.1 GB/s write when both ends support the full 40 Gbps link.

How much heat does the cable generate when delivering 240 W continuously?

At the maximum 48 V / 5 A rating the cable is certified to operate safely, and the aluminium housing helps dissipate heat during sustained high-power charging.
