I realize now that I need to invest in a better solution for recharging batteries, primarily AA's in a series of four.

What does the forum recommend for charging capacity, (mAh?), I have seen numbers like 40,000, 2,000 etc. Need some refresher on that.

I would prefer solar charging but will settle for car and then wall for last resort.

I realize I will recoup the investment over time. Interested in make/models for my purchase and what to avoid.
