AFAIK, those things estimate charge based on voltage. If a battery heats up, it’ll have higher voltage. Not necessarily for a good reason…
DON’T DO THIS. i did that by mistake once and it grilled my powerbank. was completely broken after. this is beyond stupid.
What’s stupid is buying cheap AliExpress power banks that don’t mitigate this situation safely, and instead simply explode, burning your house down…
They are cheap and if you don’t need an expensive product, they are mostly fine, but I got a free powerbank with some crappy teen magazine (when I still ocasionaly read those ad filled pieces of shit) and it died on the second charge.
Jokes aside, this is something an astonishing number of folks know less than nothing about.
Are you claiming to refute the hard evidence OP has presented?
