>> Consumer power supplies probably don't At least here in the EU they do and i think it's the case in most countries world wide? Looks like that 2014 case might have been a sub-standard charger that didn't conform to required safety standards? I actually experienced a (cheap) charger exploding under my desk back around 2015. There's a youtuber called BigClive that delights in tearing down the bad chargers. Ken Shirrif's blog is the best resource i know of for this topic though. Anyway, i feel pretty safe with the vision pro plugged in with an apple charger. The battery does get warm though... |

In that case it was a cheap USB supply, though there are other reports of similar. "Good" consumer power supply are designed to IEC standards, but to keep the cost down they are different standards to those used for wearable medical equipment. Medical equipment has to conform to IEC 60601, which governs things like electrical isolation and safe failure modes.
> i feel pretty safe
So be it. It is unlikely, but even a good power supply can fail in the face of a voltage surge on the mains. Absolutely don't wear it plugged in if there is any hint of a thunderstorm!
