Abstract
The mobile phones are play’s vital role in the present communication. The coin-based mobile battery charger developed in this paper for providing a unique service to the rural public where grid power is not available for partial/full daytime and a source of revenue for site providers. This can be quickly and easily installed outside any business premises.This type of charger will be very useful for the public people; many times the battery becomes flat in the middle of the conversation in particularly at inconvenient times when access to a standard charger isn’t possible. The power supply for the charger is determined from solar power and current supply. When we put a coin, the coin detector detects the coin and the input is given to the controller. MOSFET acts as the switch in the circuit. This circuit can be placed in public places such as Bus stands, Railway stations, Hospitals.

At the same time the supply is given to the charger for a particular time period
Summary
The mobile phone market is a vast industry, and has spread into rural areas as an essential means of communication. When a mobile phone is connected to the USB port of a computer, it utilizes this 5V supply to recharge battery. This feature is used in a solar mobile charger. It converts and regulates solar energy to 5V DC and the output will be available through the female USB connector. To this connector, we can connect a mobile phone via data. The panel will rotate according to the readings read by the LDR It will utilize the full sun light to work & power optimization is done by using the LDR. This is done by controlling the mechanical movement of the solar panel
