I'm looking for a battery-powered USB charger. Just your average USB charger. However, I have heard that when the current or amperes increases, the battery life of these USB chargers that I'm contemplating buying will decrease. And not just by a little bit at a time, but exponentially.
So maybe a charger with a current of 500mA will bring out 30% more power from the AA batteries than if I used a charger. That charger would have a current of 1 amp. Thoughts? Am I even going about this correctly?
