Adam Savage and experts from Lumafield use a CT scanner to inspect the internal engineering of different USB-C cables, comparing an expensive Thunderbolt 4 cable to cheaper alternatives from Amazon Basics and Anker.
From the video
Answers: Why are some USB-C cables so expensive while others are cheap?
- CT scanning technology
- USB-C cable engineering
- Thunderbolt 4 cable architecture
- PCB design in cables
- Cable shielding and strain relief
- Data transmission vs charging cables
What it concludes
- Expensive Thunderbolt 4 cables feature complex PCBs, extensive shielding, and precision engineering to handle high-speed data signals and power delivery safely.
- Cheap 3 dollar USB-C cables often lack circuit boards, proper shielding, and data transmission capabilities, functioning primarily as simple charging wires.
- The extreme cost of high-end cables reflects advanced manufacturing prowess, rigorous engineering, and precise tolerances required to prevent signal interference and hardware damage.
