This project presents a DIY Solar Power Bank with Wireless Charging System, an eco-friendly and portable solution for charging mobile devices using renewable solar energy. The system utilizes two solar panels to capture sunlight and convert it into electrical energy, which is stored in a rechargeable battery through a charging circuit. The stored DC power is converted into high-frequency AC using a DC-AC converter and transmitted wirelessly through a power transmission coil. At the receiving end, a wireless power receiving coil captures the transmitted energy and converts it back into DC using an AC-DC converter. A USB charging module regulates the output voltage to provide safe charging for mobile phones and other portable electronic devices. The system eliminates the need for physical charging cables, offering convenience, portability, and sustainable energy utilization. This project demonstrates the integration of solar energy harvesting, wireless power transfer, and battery storage technologies, making it suitable for outdoor, emergency, and off-grid charging applications while promoting the use of clean and renewable energy sources.
