General discussion • Re: What Will Happen to Raspberry Pi Zero 2W If You Connect 2 Micro usb power supply?

What If I Connect
1: micro usb power supply from charger or powerbank
And
2: micro usb power supply from charger or powerbank

All at the same time on raspberry pi zero 2w since they have 2 micro usb?

I believe that in theory, you could probably blow up your Pi. It would require an unfortunate series of coincidences. Earlier USB-PD standards modulated the negotiation of higher voltages and currents over a 24MHz signal coded on the Vbus. Assuming the Vbus and ground pins are electrically connected between the two connectors, it *may* be possible that a battery bank could spot that it is being powered, and negotiate a higher voltage than the 5v the Pi is expecting, resulting in the release of the magic smoke.

Dunno. Just seems feasible.

As eveybody else has said: don't do it.
