How do you recharge the AA batteries when you're out backpacking, etc? If you simply carry enough to last the duration of the trip, wouldn't a power bank hold the amount of power of the AA, but in a more compact package, and be faster to recharge than a bunch of AA when you do have that option? I'm genuinely asking, as I haven't used AA batteries in a very long time. Just based on my general knowledge of batteries, I'm pretty sure my thoughts are correct since lithium holds the most power compared to other battery compositions. You could also more easily charge a power bank from a dynamo. You just plug it in to your power converter and you're done. It's like if you could just plug your AA directly into the dynamo to charge. Am I genuinely missing something, or is it strictly a preference thing?
