Solar Powered Mobile Power Bank Systems
The objective of this research is to design a Solar Powered Portable Power Bank for mobile phone using sunlight as its ultimate power, which can be used effectively during disaster events. It has in built solar panel which converts the solar energy to electrical energy. The charge is then transferred to a battery for storage of charge for further use, with the battery having a microcontroller indicating the percent of charge present in the battery. The battery is connected to a charging circuit having an USB port as output to the respective Mobile phones.
