The Solar Power Bank with Wireless Charging System is a renewable energy-based project designed to charge mobile devices using solar energy. The system uses a solar panel to convert sunlight into electrical energy. This energy is regulated by a charging circuit and stored in a rechargeable battery for later use. The stored energy is then supplied to a wireless power transmission coil, which transfers electrical energy wirelessly to a receiving coil through electromagnetic induction. The receiving coil converts the transmitted energy into electrical power, which can be supplied to a mobile phone through a USB charging interface or a compatible wireless charging system. The proposed system provides a convenient and eco-friendly alternative to conventional power banks by utilizing solar energy and reducing dependence on grid electricity. It is particularly useful in outdoor activities, remote areas, emergencies, and locations where access to electricity is limited. The project aims to demonstrate the practical application of renewable energy, battery storage, and wireless power transfer technology in portable charging systems. Overall, the solar power bank with wireless charging offers a sustainable, portable, and efficient solution for charging electronic devices.           Objectives:
