AFAIK, those things estimate charge based on voltage. If a battery heats up, it’ll have higher voltage. Not necessarily for a good reason…
No.
He broke science.
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?
Lisa!
In this house we obey the laws of THERMODYNAMICS!!
Fire hazard speed run
I don’t think it would it be too bad since it’d have a current limiter would it?
this assumes it’s not a dogshit quality power bank
i have a similar one and its shoddy enough that i wouldnt bet on it.
Just don’t let a dog do a bad chew.
Firefighters hate this one easy trick!
[The Free-Energy Trick Big Companies Don’t Want You To Know]
I once charged my phone by holding it over an induction cooktop. Only for a couple of seconds though as I was afraid to fry my phone, but it did it over 40cm
I always wondered what would happen…
You’re welcome, now you don’t need to risk your own phone in order to know :p
I used to take those 9-volt battery connectors, wire them up together and then recharge a dead 9-volt with a brand new one until the tester strip thing showed they were both even. Surprised they never popped because they would get really hot lol
My dad used to recharge alkaline batteries with a special charger, but that was quite useless
Those chargers are really dangerous. It is technically possible to recharge a disposable alkaline battery a few times, but you’re never going to get more than a half charge, and it will fuck up the internal chemistry turning each battery into a tiny potential pipe bomb.
At least that charger had a safety feature that would not charge a battery if it was too worn
You shouldn’t charge a battery pack at the same time you’re discharging it unless it’s specifically designed to allow that. Most consumer power banks are not designed to do that.
It’s doubly stupid to charge it from itself.
I once did that with a Samsung powerbank I have. Daisy chained the powerbank to charge itself and a phone in sequence.
The only thing that failed afterwards was one of the cables, but suffering a loss was definitely the reason I didn’t attempt to do that again.
Seat’s taken
I’ve heard the cheap ones don’t like doing this too much.
100w charging, getting pretty toasty!
Ah, the flintstone of the modern age
