The solar charging is poor, 16 Dec. 2011
I bought it thinking that it is high capacity and bigger so will charge faster and efficiently but I soon realized that the charger hardly charged through light. Above all, the sole reason of buying it was that it could charge the ipad and phones while they were not in use. I was disappointed, as the indicator lights kept blinking all day as if it was charging but it did not. The solar charging was grossly inefficient. A full days charge could not even start the charging process. Tried it for 5-6 days, same result.
I also tried charging it through my laptop which it did. It gave good power to my ipad but it was not as if it charged the ipad from 10% to 90%, a full charge from laptop gave my ipad approx 25% charge.
Another problem is it does not charge any device directly while under sun. It first stores the charge in the built-in battery and then you have to transfer the charge once the battery has charged and that happens quickly. Its not the best if you are looking for something to charge your device directly from sun and at the same time.
