Best solar radio that I have seen. I was About to send it back after a week because it would not hold a charge. Either way that it was charged, solar or adapter it just would power down in a short period of time. After getting a return authorization from Kaito and as I took out the AA batteries before packing I noticed the problem. The switch for the reading light was in the on position. So I gave the radio one more chance, after turning the switch to off I recharged the radio. And LO & Behold the radio holds a charge for a good long playing time. As I said the best solar radio that I have seen.
