Save your money,
This review is from: Solar Battery Charger, Charges 4 AA, AAA, C or D cells + 7 Volt Power SupplyI bought this to try to charge my rechargable AA batteries. I am not an electrician but figures no more than it cost, why not order it. I ordered and it came in promptly. I inserted my batteries and put in the sun. After a day, I put the batteries in the lantern they came out of and was excited to see how it worked. Charging with electricity would give me 4 hours of continous use. The light shown bright for about 45 minutes and died after an hour. I recharged batteries outside for 3 days and figured this would do the job but results were the same. I am not an electrician but learned that rechargable batteries have something called a mA rating. My batteres were rated at 2500 mA and the box indicated the limit was 500 mA for the charger. If you order this charger be aware of this and check the battery limit first. This charger works but only as a toy really and has very limited charging abilities. I would say save your money and put it into a charger that will do the job. I'm posting this since it was not explained on the ad. Hope this helps someone.

Well your correct in that you're certainly not an electrician and not to savvy either. Before you go downgrading something perhaps you should consider your lack of knowledge in that area. The 500mA rating for the charger only means it will take 5 hours to charge a 2500mA battery if completely drained, which they rarely are. Did you get that?..500mA x 5 hours = 2500mA.. In essence the mA rating of ANY charger really only indicates how FAST it can charge, not the capacity of a battery it can accept or charge. The voltage dictates which ones can and cannot be charged. So this charger can easily charge that 2500mA battery. Instead of using a lattern wihich may have a bulb which is designed for 1.5volt batteries you should be using a volt meter to check rechargeables which are 1.2 volt to see if you are actually getting a full charge. Your method means squat.
Obviously this charger and its concept are over your head, so maybe saving that money and buying a standard book about batteries might be more useful instead of warning others with misleading information.
