Nowadays with the advancement in technology, smartphones have become very common. But the smarter the phone is the lesser is the battery timing. This becomes a problem at sometimes. For example while travelling if the mobile battery gets low, and we have to contact anyone, and also we have no power source to charge the battery. So my prime purpose is to solve this problem. For this I have designed a mobile charger which charges the battery with AA size cells if we have no power supply. So now this portable device can help us charge our battery anywhere only with AA size cells. Further I modified it so that if we have power supply it charges the battery with that and in the absence of that it charges from cells. In this way I have tried to solve this problem.
