Solar charging of the 7120 is automatic and the cell phone can be charged even when the phone is turned off. Personally, I think its solar energy is very good. The humidity was so high in Guangzhou the day before yesterday. and the sun was very weak and no shadow was visible. I tried. It can be charged with the 7120, but it's a bit weird to hold it in your hand all the time~ haha
But apart from solar power and appearance, this phone has too few functions< /p>
