You should look into solar chargers. Africa has a lot of
sunshine. Maybe a bit too much, at times.

If we had a bit more time, I'd offer to wire you such a
device (suitcase with power cord, step down transformer, and
lots of 110 VAC outlets).

They work better in the daytime than at night... which is when they want
to recharge their stuff.
