Access to electricity remains a challenge in many rural communities in India, with power outages being a common occurrence. Yet, mobile phones have become a vital tool for communication, entertainment, and social connection. This has created a significant business opportunity gap for low-cost mobile chargers that can be used during power outages. In this paper, we present a solution to this gap by introducing a hand-crank cell-phone charger. The device uses motion energy generated by a hand crank to convert into electrical energy to charge digital devices, including mobile phones, tablets, cameras, GPS devices, flashlights, and Bluetooth speakers. The device can be easily transported, has a small form factor, and features a standard USB port. It can output a maximum voltage of DC 5.5V and a current of 600mA.This paper details the process of designing, assembling, and testing the hand-crank charger. We argue that this innovative product could be a game-changer in rural India, where access to electricity is limited, but mobile phone usage is high.
