The PowerFilm USB + AA charger is probably the best product and design I have seen in terms of AA solar chargers, especially for backpackers. Stores like REI and EMS need to carry this charger. Basically, this is 2 devices in 1. It is a solar charger for NiMH batteries (2 NiMH Sanyo 2000mAh batteries come with the product). It is also a voltage transformer that takes the 2.4v of the NiMH batteries and ramps it up to 5v allowing you to charge a USB device (like a cell phone or iPod) using the charged batteries, even when it is NOT in the sun. This means that you can lash the unit onto your backpack or car dash without having to tether your phone to it all day, and then draw from the stored energy in the batteries at night. I charged two batteries in the sun with no problem and then charged an iPod Nano 2G while the solar panel was folded up, and it work perfectly.

In terms of backpacking, I can't imagine that there is a better option. It is light weight (I weighed it myself and it's 4.95oz without the batteries, 6.80oz with batteries) and has a large enough solar panel to get the job done. It also has a number of grommets for lashing the unit to the hood of a backpack, and the solar panels themselves are just about the width of a hood on most backpacks (not daypacks for school, but full-on internal frame Gregory, Dana, Osprey, REI backpacks). Most AA solar chargers have a ridiculously small solar panel that would require a week in the sun to charge a AA battery. This unit can charge two dead 2000mAh NiMH batteries in 5 hours of full sun. Given that you might have a cloudy day, that is exactly the type of power you need.

In regard to the reviewer who gave this a 1/5, you have to install the batteries into the unit and charge them some before it will produce sufficient USB power.

I know solar chargers aren't that powerful and can be fragile, but I decided to gamble on this one because I really like the concept. I could not be more pleased! Very very versatile. Rugged design, super light, folds up small enough to fit in your pocket, charges AA's AND USB devices (using AA power). I hang it in my window before I go to bed and by the time I'm leaving for work, the batteries are fully charged. I've been experimenting with it to see how good it is --I mainly bought it for camping and when I travel for work (all too often I find myself sitting in airports for hours).

Here's some random info that I would have found useful in a review:
1) Folds up to about the size of a large men's wallet.
2) This thing works waayy better than those Radio Shack solar chargers (which you have to buy charging tips for, I might add).
3) I was planning on making a MintyBoost, but now I've got no need as this is essentially a MintyBoost that charges itself!
4) The extra flap next to the battery compartment can be wrapped around something (like a pole) and it fastens to itself with velcro. In other words, there is usually no need to use bungees or string to tie it up to something if you're outdoors on a camping trip or whatever.
5) The solar panels themselves are flexible, really flexible, like you could fold them in half (though I wouldn't recommend doing that).
6) Battery compartment is NOT waterproof, but it is on the underside (from the solar panels), so a light drizzle isn't going to harm it.
7) Charges 2 AA's at a time (I wasn't 100% certain of this when I bought it).

Having read the reviews I was very excited to receive this unit! As has been noted, it is well constructed, of good materials, is very lightweight, and comes supplied with high quality Sanyo Eneloop batteries. I was very excited to try it out, and anticipated using it on long distance cycling tours. Unfortunately, my experience varied significantly from other reviews. Perhaps I received a defective unit, or perhaps it had defective batteries that did not achieve/maintain a proper charge. Or perhaps, it is just the Northern climate in which I live. But nonetheless, here was my objective experience, in southern Minnesota, in mid to late May (in terms of intensity of sun). All testing was done outside on clear days, without any trees or other sunlight obstruction. After properly installing the batteries, and placing the device in direct sun, the appropriate charging lights illuminated and the device achieved a full charge in 5 to 7 hours, depending on how close it was to mid-day. I thought this was reasonable for a relatively northern latitude, for a unit of this surface area, and I was excited to proceed with using it.

Unfortunately, my enthusiasm quickly waned. Upon attaching an iPhone 3GS (after fully charging the solar unit and with the light indicating a full charge) and running a golf GPS app, the battery drained from 100% to approximately 40%, over the course of a 4 hour round of golf, on a clear day in mid-May. This is incrementally better than the usual draining from 100% to 20% charge over a typical round without any charging device. So, it did slow the loss of charge, but it was nowhere near able to maintain a full charge.
