As part of an initiative to educate middle school students about electrical energy, the country of Switzerland has sponsored several STEM programs encouraging teachers to integrate hands-on experiences in their classrooms. This paper highlights the design and development of a versatile cell phone charger capable of accommodating various power inputs (hand generator, solar panel, AC, etc.), charging a cell phone and displaying the flow of electrical energy for educational purposes. A working prototype utilizing a SEPIC DC-DC converter was built and tested based on specifications provided by the project sponsor. Real-time power monitoring was accomplished by using voltage and current sensors providing signals to a Raspberry Pi microcontroller, and outputs were presented on an LCD touchscreen display. System testing shows further refinements are recommended including the implementation of an additional charging mode as well as slight modification to the custom PCB design.
