Exceeded expectations

I purchased this charger in case of long term power outage (earthquake, ice storm, nuclear war, cap and trade-caused blackouts), with the intention of always having light by recharging AA batteries and using them in LED flashlights and lanterns.

I used this charger on Oct. 24 on a sunny day in central Illinois, on a pair of partially discharged NiMh 2400 maH batteries that read 1.2 volts. The charger brought them up to 1.36 volts quickly and showed them as fully charged. Impressed, I decided to purposely discharge a pair of AAs by running them in an incandescent flashlight. One battery read 0 volts and the other was at 1.0 volts and the filament of the bulb was just barely showing a red glow when I put them in the charger. The charger accurately diagnosed them as very low and started recharging them in a trickle mode. One trip to Walmart later, (1-2 hours total charge time) and both batteries were right at 1.36 V. I also ran a separate 4-pack of partially discharged batteries and they were charged fully in 1 hour.

Based on this small experience sample, I am very happy with this product, as it surpassed the charging times on the box on a sunny day, even in late fall, with the sun very low in the sky at mid-day.

I also feel the build quality of the product is high, based on first impressions only.

This charger is also very small, folding up into a box smaller and thinner than I expected. It also comes with a 4-pack of the excellent low-discharge Sanyo Eneloop batteries, which are a $8-10 dollar value.

It also has grommets to make it easy to use string or cord to affix it to a backpack or tie it down in windy conditions. I am planning on making a set of copper wire supports that can be used like tent stakes to hold this charger in place on flat ground or to prop it up to get true perpendicularity to the sun to maximize the energy capture.

In summary, I love this charger and highly recommend it.

Excellent charger

I recently purchased this charger's cousin, the Powerfilm USB / AA Solar Charger, and was so impressed with that one that I decided to get this one, too. I was not disappointed; this one is just as high quality as the USB version, only it trades 2 AAs for a USB charging device. These are without a doubt the best small AA-type chargers I have ever used (I've been though about a half dozen). These are ideal for either power outages of those trips in the wild where you will be without civilization for awhile. Truly wallet-sized, yet can keep your AAs going until they finally die on you.

Well worth the money.

Used it yesterday for the first time to charge 4 Eneloop AAs. Put it in the window, came back 6 or so hours later to find them fully charged!

Folds up nicely. Has velcro to keep it tightly wrapped when not in use, and several metal grommets for securing with 550 cord.
