I am planning a 6 day camping trip, but my camera battery will only last about 1 day. I could buy 6 batteries but that would cost hundreds!

I do have a battery charger (plugs into a wall outlet)… does anyone know of a small generator or maybe a battery that gives power to an AC outlet that I could take along? It wouldn't take much power to charge my battery, I just need a way to do it from the top of a mountain.
No cars.. this is the top of a mountain!

I use a small solar panel to recharge my SLA's that I use for my backpack ham radio station.

The panel is from Volkswagen! They ship cars with a solar panel to keep the batteries alive in transit and storage. Then the dealer pulls out the panels and can sell them or return them to Volkswagen. They end up on eBay for about $15.00 each.
