I suspect some of you have already expended skull sweat on PV cells for use recharging your stuff while out in the woods.
I'm interested in finding either a cloth backed folding or roll-up PV set up, should be able to charge 2 or more AA Sanyo/Enloops to full charge in 4-6 hours, work in full sun OR overcast/cloudy weather, have a USB port, and be at least water/rain resistant if not actually waterproof. I'd actually prefer it not have a built in battery pack ('cause some day it's going to go bad and then I'm stuck with it), but I could live with it if everything else was good.
I've run across some folding cells from Powerfilm, and one of their models is on sale for about 4 bucks, but it's not quite there...close but no cigar.
So Hive Mind, what products do you suggest?
*fake edit* If anyone knows of a packable sized spring powered DC generator/battery charger that would be a bonus. Think of the original Baygen radios (the one's with no batteries).

I've had the Goal Zero for a few years, as technology goes, it's now dated. I believe GM has or had an Orange (solar)joos.
My .02 is that as the tech advances we see gains going back and forth between solar and battery. I think currently it's on the battery side, but I could be mistaken. I know if I'm in a base camp situation (A few days in one place) the GZero seems to work well. I can charge the battery pack, or direct charge a number of things. I've found if I'm on the move (Backpacking/hiking) a good Battery pack (Anker, etc) works better to keep my devices charged.
If your hiking, prime sun will be early morning, and late afternoon before you get moving. You may get some on the move, but it wont be prime. Different PV's will act differently in those situations...

Ideally the PV will be of the cell type that has the best performance over the widest range of conditions rather than great performance under only one ideal set of conditions.
