Solar AA Battery Chargers

[Clam]

Anybody have any experience with these? Silva and Brunton make them for recharging AA batteries. They cost from $38 - $99 and weigh less than half a pound.

Note: Think small.
I am not really interested in huge things that will power downtown Vancouver. Small for backpacking purposes.

Here's a couple, but I have not used them. I'd look for a flexable panel so you can roll it up when done.

A freind of mine gets the cheap solar outdoor lights then takes the lite part off. They even come with batteries.
