2.0 out of 5 stars It doesn't get full charge January 23, 2011
I was so happy to find this product but my first K3 wouldn't charge past the medium level. I talked to the manufacturer. I had to send it back to them, which cost me $ since I'm not in the US. They sent me another, but the same thing happens. I followed all procedures but nothing makes it fully charge, not even the AC power. It's a pity, even if the price now is much lower I'd think twice. Unfortunately it doesn't have power enough to charge a cell phone.

4.0 out of 5 stars better than nothing, but short on expectations August 2, 2010
Amazon Verified Purchase
First off this was a must have for charging the cell phones in camp! It kept the ipods and cameras alive too...with a little time management. It did fall short on what the maker states however. Supposed to get a full charge with 8 hours in the sun....it doesn't. Here in the islands we get solid 10 hr. plus days of sun in the summer plus all night wind power from the Trade-Winds and this would only go to 3/4 charge. With a little time management it still doable so its not a big deal, just be advised that the claims are a little over what your actual results will be.

1.0 out of 5 stars Good idea, but... June 15, 2010
Amazon Verified Purchase
This product has two methods of generating power, and they were equally disappointing.

The Wind Turbine:
This part was about as sturdy as a pinwheel, and after a brief stint on the front of my motorcycle, I found that it (the turbine) had broken off of the charger altogether. Even before it broke, it never really achieved a full charge.

The Solar Panel:

I'd have to say that I either received a lemon, or this product is a fraud that belongs in the late-night QVC catalog. I left this product in the sun for an entire day. An ENTIRE DAY. I got about five minutes worth of charging out of it each time I did so. I had hoped this would serve me well while I was traveling out of country, but it turned out to be a waste of money, space and energy. On top of that, there was no return option when I purchased it. This may have changed since I bought the item a year or so back.

TLDR: Doesn't work. Save your money and rub your hands together to create static electricity instead.
