Subject: Inca Trail and Battery Charging

What are some ways to manage the lack of any way to charge devices along
I can give them some USB power banks, though these are rather heavy to
carry and the losses to charge one battery from another battery are
From what I've seen of the hand-crank USB chargers, they are really not
practical, you'd have to stay up all night cranking just to charge a
There are some small solar panels that hang on a backpack, that claim to
deliver 500mA of current, and that are about $100. These could probably
charge a 1200mAH battery in five or six hours.
There is a wood-powered USB charger, but I don't know if it's possible
to find fuel along the trail. This would be good to use at night, since
solar obviously won't work.
Or I can just buy them four or five spare camera batteries each. These
are for compact P&S cameras, not for SLRs, and after-market batteries
are $10 each.
Has anyone here come up with a good solution for trips of several days
where they will not have any access to electricity?
The other suggestion I made is that we resurrect one of our many old P&S
film cameras and that they take a bunch of film.
