Length 3.94 ft. (1.2m)

  • Charges up to 240W with PD 3.1 and PPS
  • Transfers data at 40Gbps theoretical maximum speed
  • Drives a single display at 8K 60Hz
  • Works with Thunderbolt 4 and earlier USB standards
  • Built to withstand 10000-plus bend and plug cycles

3.94 ft Thunderbolt 4 cable

This 3.94 ft USB4 cable carries Thunderbolt 4 signals and supports 240 W power delivery at 48 V/5 A. It drives a single 8K or 6K display at 60 Hz, or two 4K displays when two cables are used. The cable is fully backward compatible with USB 2.0, USB 3.2 and Thunderbolt 3 devices.

Replaces slower charging and data cables

It upgrades any legacy USB-C lead that tops out at lower wattage or 10 Gbps speeds, eliminating the need for separate power, video and data cords. The jump is worth it when you connect a high-power laptop, an 8K monitor or a Thunderbolt 4 dock that demands 40 Gbps bandwidth and 240 W charging in one run.

Check host and device capabilities

Verify that both ends support USB4 or Thunderbolt 4 to reach 40 Gbps and 240 W; actual transfer rates fall to 2.8 GB/s read and 2.1 GB/s write depending on hardware. Ensure your charger and monitor accept PD 3.1 or PPS profiles for full power, and confirm the 3.94 ft length fits your desk layout.

Questions about this item

What length is the BFKK Thunderbolt cable so I can check it reaches my monitor?

The cable is 3.94FT long, giving you about 1.2 metres between your host and display.

Which port orientation do I plug in first to get 40Gbps data and 240W charging?

Either end works — both connectors are USB-C and support the full 40Gbps, 240W (48V/5A) specification.

How often should I expect to replace the cable if I coil it daily?

It is rated for 10,000+ bend and plug cycles, so daily coiling should last years before replacement.
