Battery Pack

"Can I power the Porta Pi Arcade with a battery pack?"

Yes. That is the short answer.
"How" is all up to you. I did a half-assed attempt a few years ago using rechargable cordless drill batteries. But I expect you'll want a more eligant solution. I would suggest removing the amplifier and replace with a headphone jack:)


There are many battery packs out there, feel free to show me what you figure out!
