I'm a noob in raspberry pi and in engineering in general. I had an idea for a project but it requires it to be somewhat portable so I need to power the raspberry somehow. I read this article Where it says that it's possible but the rpi might be fried due to current spikes. I plan on powering it with AA batteries so do these have voltage or current spikes?
I also read on ups Hats that regulate the voltage and current but it's unavailable in my country
Thanks in advance
