BFKK Thunderbolt 4 Cable 240W 40Gbps 8K 10ft

This USB4 cable carries Thunderbolt 4 signals at up to 40 Gbps and delivers up to 240 W of USB PD 3.1 power over a 10 ft length. It supports a single 8K display at 60 Hz or dual 4K monitors at 60 Hz. The cable is built for professionals who need high-speed data, video and charging in one run.

Check host port and device capabilities

Verify that your host and peripheral both offer a USB-C port with Thunderbolt 3, Thunderbolt 4 or USB4 support to reach the rated 40 Gbps and 240 W. The cable is backwards compatible with USB 3.2, 3.1, 3.0 and 2.0 devices, but speed and power will fall back to the lowest common standard. Confirm that your monitor or dock accepts DisplayPort Alt Mode over USB-C for the 8K or dual 4K video modes.

Thermals noise and power draw

The cable is passive and has no active cooling, so it produces no noise during operation. Power delivery peaks at 240 W (48 V at 5 A) when both ends negotiate PD 3.1, and the supplier notes stable voltage to protect connected gear from overheating. Under normal data and video loads the conductors run warm but within specification.

Questions about this item

What is included in the box and do I need to buy any adapters separately?

The box contains the 10 ft USB C to USB C cable only; no separate adapters are required for Thunderbolt 3, Thunderbolt 4 or Type-C devices.

Should I choose this cable for 240 W charging or would a lower-wattage version be enough?

Choose this cable when your laptop or dock needs up to 240 W (48 V / 5 A) PD 3.1 power; a lower-rated cable would limit charging speed on high-power machines.

What does the 40 Gbps figure mean when I connect an M2 MacBook to an 8K monitor?

It delivers the full 40 Gbps bandwidth needed for 8K at 60 Hz or dual 4K at 60 Hz HDR, provided both host and display support that mode.
