>I can just buy more power at the gas station.Why aren't AA powerbanks more popular?
>>107704182ragebaitimagine going out of my WAY to a fucking gas station to PAY for more AA batteries instead of just connecting a cable at the comfort of my own home when I'm not using it.
>>107704273What if I'm at the mountains?
>>107704182you can also buy new appliance whenever old ones battery dies. or carry a generator with you. or neck yourself. all of them as fine options as what you mentioned
>>107704285buy a shitty foldable solar panel or some hand crank charger that will give you arthritis or even better yet, plan ahead so your ass is not stranded.
>>107704408What if my wrist is tired and it's cloudy?
>>107704430unless a massive cataclysm is causing the sky to take an absolute, dark, pitch black color, there's still going to be light. 20 watts or 100 watts, you need less than 5 percent charge to look up maps or call emergency.On the off chance that it is happening, find a good vine and rope yourself. Actually do that anyway.
>>107704182>AA powerbanks1. there is no "AA" you stupid merican NIG/g/ER football field measurement .. boomer terminology 2. all depends on chemistry (LiMH, Li-ion, etc.)3. "classic" for 1.5V. How need this shit nowadays if you can get 3.7V (nominal voltage, and 4.2V max charge).4. Learn fucken BASICS (cons and pros) about NCA, NMN, etc.5. You can use several battery elements for "powerbank" only if they are permanently in-place or will face voltage imbalance\internal resistance differences\etc.once again NIGGER ... your idea and question is stillborn
>>107704536It can take NiMHs and charge them or regular alcalines for external device charging only.
>>107704430You're going to need to find two very specific rocks and bang them together. https://en.wikipedia.org/wiki/Piezoelectricity
>>107704182Shit power density. They're only useful for charging AAs to put in other things. It's a neat trick they can theoretically run your phone for 30 minutes, but the novelty wears off pretty much immediately.
>>107704536Are you being intentionally retarded?
>>107704536>america invents dry cell batteries>europe invents the name>gets angry when americans don't use the nameAt least when RMS gets mad about GNU/Linux he wrote the compiler. Euros just sit in the corner and seethe because the world keeps going without them.
>>107705600>>america invents dry cell batteriesSo how bad does it make you seeth that most likely the first to bring solid state lithium to market gonna be the chinks or the japs?Further cementing your obsolescence in yet another field...
