Energy is the most vital source of Earth's power consumption. (EPA United States Environmental Protection Agency, 2020) Transportation is one sector that consumes the most energy but emits carbon emissions. In this study, the researchers aim to develop a Pedal-Powered Generator that would be an alternative source of energy that can charge multiple devices that is more efficient while integrating with safety attachments. This experimental study investigated the relationship between voltage and the number of devices connected to a Bicycle Powered Mobile Charger. The researchers aimed to develop an efficient charger and measured the electrical power output and efficiency using voltage, current, and mechanical power input formulas. The study involved assembling the machine and conducting testing procedures with different cell phones. The results contribute to the development of a Bike Powered Mobile Charger. The researchers conducted tests to determine the current efficiency of the mechanism. According to the result that the researcher found. The pedal- powered generator is fast and reliable during emergencies and long rides. The machine can generate 3% within 5 minutes of pedaling. So it can charge a cellphone within 2 hours and 44 minutes with a 5080 mah battery. The pedal-powered generator can charge eight mobile devices simultaneously due to its 8 USB ports. The study's findings prove that the pedal-powered generator is a highly efficient replacement charging system, supplying power to the bicycle's horn and lights. This novel system demonstrates its capacity to supply a sustainable and dependable power source for these crucial components by harvesting the kinetic energy produced by cycling.
