Thanks everyone for a lot of great suggestions. The really cheap ones somewhat concern me because they take so long to charge and are likely not very robust. Uganda is a very poor and backwards country. From things that my daughter told me I doubt they have the option to buy a replacement if the need should arise. For example where she’s at there’s no such thing as new shoes; the stores only sell used ones. So a NiMh charger would likely be unavailable
I’m leaning toward buying a handful of the cheap ones that Brad and MoutainKing mentioned, and pairing them with the Soshine SC-F3 charger that Chloe reviewed: Re-review: Soshine SC-F3 Ni-MH LiFePO4 Charger. The Soshine’s are only $5.92 in quantity so it’s close to what I wanted to spend.
Maybe I should just bring Hybrid solar powered flashlights. Don’t have to worry about chargers and are fairly reasonable at about $12 each (for the lower lumen ones). But they don’t have the ‘wow’ factor. When she lit up her ZL SC52 one night they thought it was an alien Star Trek type device
