I have one here somewhere but it needs strong sunlight to charge the batteries. Once it gets slightly overcast, the amperage needle just drops off and your batteries will practically never charge. However, in direct sunlight, AAA's will charge in about 1 hour, AA's in 3 hours and the solar panels are reasonably tolerant of the suns position changing over time. If you set it up that the sun is to the left of optimal position, then it will progressively get better over time and then worse by the time the batteries are hopefully charged. They're good but fiddly. Cheap too!
