Hey /diy/ , i found this old solar charger, i tested the cell with a voltimeter and it works! so, i'm pretty sure that all the board works.
can you tell me how to wire it to use it (charge it) with that 9v battery?

I'm not sure how carefully you have to handle rechargeable batteries, but you will have to use a DC-DC converter from either the regular battery charging slot or the usb port. My only experience with such devices is for guitar pedals, so whatever I suggest is probably more lossy than the ideal solution. Look up the MAX1044 IC and the LT1054 IC to get an idea of what I'm talking about.
