My current means of powering things is USB rechargable batteries. I have a about five of them that range between small 3000-5000mah ones to a big 20000mah interstate battery jump starter pack. Is there a device that lets me add all their power together into a centeral power source so I don’t have to keep swapping them out?
Or, I mean, it could just wire all the positives together and all the negatives together and hook that right into your target device.
It’d be the same output voltage regardless. A little less internal resistance, and lower step down in the later phases, but neither should make a difference in what you’re powering.
Kinda like how there were those converters for the GameBoy back in the day that let you put C batteries into it. Same principle.
