What this cable does
The BFKK Thunderbolt cable is a short 0.3 metre link for Thunderbolt 4 and USB 4 devices. It serves laptop owners, dock users and anyone connecting an SSD, eGPU or monitor to a Thunderbolt 3 or 4 port. Buyers who need a longer run or a different connector type should look elsewhere.
The deciding specification
It carries 40 Gbps of data, 240 W of power at 48 V and 5 A, and drives an 8K display at 60 Hz or dual 4K at 60 Hz. The USB-IF certified build includes an E-Marker chip and supports PD 3.1 plus QC 4.0, FCP and AFC fast-charge protocols.
Heat, noise and power draw
The cable itself produces no noise and negligible heat during normal operation. It simply passes up to 240 W from a compatible charger to the attached device without adding measurable thermal load to the setup.
