I tried running a Pi Zero W on a 10000 mAh powerbank with qualcomm quickcharger capability (https://www.biltema.se/kontor---teknik/mobiltillbehor/powerpacks/powerpack-10000-mah-2000041816) . The first few times it worked ok, it ran for more than 24 hours but then the Pi suddenly stopped working. It appears to be fried:
No response when plugged into PC in usb cable (see link https://www.raspberrypi.org/forums/viewtopic.php?t=58151 bottom post on Zero)
When I plugg the pi into a regular pi-powersupply it smells of burning circuits and either the chip or the components between the chip and GPIO-pins quickly gets hot (I use a thermal camera but it is hard to judge exactly what component gets hot, its only a pinprick).
No reaction on entering a fresh SD card.
Finally, when I tried the PC trick again I used a thinner data USB cable and it got very hot, along with something sounding like a dying mouse. I think I may have fried the USB outlet on the PC too. If the damn pi wasn´t fried before it probably is now.
SO, probably quite fried!
Now the questions:
Does anyone have similar experience?
Could there be another reason why the Pi fried, e.g. bad power cable, short circuit, just a bad Pi?
Regarding #2: I dont think qualcom will jack upp power to 9 or 12 v without communication with the receiving device, then again, this is a cheaper powerbank.
I also checked the cable and it does not appear to be broken though it could still be an internal break and short circuit.
Also I used the old SD-card in a new Pi and it seems to be working. Will check again in a few hours.
