Slow-proofed and worth the wait. Worth its weight in flour.
Summary
The article exposes how USB-C cables are not all created equal despite having the same physical connector. Many cables lack proper certification, fail to support full data transfer speeds, power delivery capabilities, or video output. The article explains the technical differences between USB-C cables (USB 2.0 vs 3.0/3.1/3.2/4, Thunderbolt, power delivery wattage), the problem of misleading marketing and counterfeit cables, and recommends that consumers look for certified cables (USB-IF certification, e-marker chips) and buy from reputable brands. The "only real solution" is to understand cable specifications and buy certified, properly labeled cables rather than assuming all USB-C cables are the same.

Just because a cable fits doesn't mean it will work the way you expect it to.
The only real solution is to buy certified cables from reputable manufacturers who clearly label what their cables can do.
