I am rather surprised that works. I thought any modern device would have overload protection in place. I think I even remember accidentally tripping it on some device, but it would just reset after reboot.
I also tried to see the max output current of my previous phone this way. Load it up till the protection trips. Result: Stable up to 2.1A, tripped at 2.5A.
Oh, yeah. A Xiaomi phone charger I have also shuts down if I either overload it or immediately load it near max rating rather than gradually increase the load.
People used to do this in the UK with their ZX spectrums.
Maybe they are poking a hole in the lithium battery
once put usb-c in a usb-a port and my desktop pc performed an immediate reboot without any permanent harm…
