The problem isn't generally fake cables, it is: 1. Cables have radically different capabilities - they may charge at 60W, 100W or 240W ; they may be limited to 480 mbps transmission rates or go all the way up to 40 gbps transmission. Up until now, the market has not regulated such that you can tell the difference when you grab a random cable, or necessarily tell the difference at time of purchase 2. Devices like the Nintendo Switch and Raspberry Pi shipped with broken implementations. For instance, the RPi would not work with cables that _supported_ over 60W charging rates.
