One type of wind-powered battery charging will be explored in this paper. Wind-powered battery is an instrument which combine mechanical and electronic devices to charge small devices like mobile phones. With the rapid development of global economy, people continued to carry more portable electronic products, which are drained or discharged as a result of longtime uses. This can be used in times of power interruptions, outdoor activities where charging are necessity. It is designed to install fixedly in home rooftops but can be detachable and carried whenever necessary. It is an energy saving and eco-friendly device and function by wind velocity. The device consists of wind turbine driving a generator and operates at variable speed. It consists of three modules which are power supply, power storage, and phone charging module, all performing different functions. The power supply module consists of physics, principles, and design. The power storage module includes the components' parameters responsible for the restoration of energy to the battery after it has been used to charge mobile phones. This paper analyzes the property of the system components. The effect of parameter variation and the system configuration on the system performance are also investigated. Recommendations to improve the system performance are suggested. The researchers highly recommend to design weightless and most efficient as well as the high efficient mechanical design of rotor.
