Misuse/abuse, altering the unit, etc. Sure.
But what specifically degrades over time to a point that makes the unit be simultaneously operable and dangerous?

I'm genuinely curious. I've been involved in tech startups for 25+ years, ranging from large scale telco equipment to consumer electronics and battery-powered devices. I've never heard of power supplies with an expected degradation curve. All the times I've seen field failures of power supplies it has been related to voltage surges or unanticipated failures from faulty components. I do not recall ever issuing a warning in manuals or documents related to anticipated power supply failures that made the units unsafe to use. I would think that if we actually *expected* such a thing, and expected the user to read and heed such a warning that it would create a huge liability issue for the company.
