This is a circuit solar charger via USB cable emergency , it is an alternative circuit that uses solar cell and LM317 to regulate and make a recharge via USB for electronic equipment that can be IPODs , cell phones , MP3 , tablets , etc. .   The simplicity of the circuit can be noted that he does not have much appeal, but it's enough to make a simple battery charge . The Solar Cell should be 12v current should be enough for loading , 10 % of the batteries .   Battery Charger Circuit using Solar Cell Circuit Diagram

4.2.2.2 Dry Cell The dry Leclanché cell or simply dry cell is useful because it is compact and portable. It is constructed with the same materials as the wet cell, except that the electrolyte is in the form of a paste or jelly. The zinc electrode is in the form of a can, as shown below.  Dry cell The chemical action is the same as in the wet cell and its e.m.f. is 1.5 V, too.
