Overcharging mobile devices is a common issue that harms battery health, wastes energy, and increases carbon emissions. To address this, The Catalysts developed the VIGI Charger—an innovative solution promoting responsible charging and environmental sustainability. Using micro:bit LED lights, it visually indicates battery levels: red (1–10%), orange (20–60%), and green (70%+). An alarm sounds when charging is complete, prompting users to unplug their devices. Combining visual and auditory alerts, the VIGI Charger helps prevent overcharging, supports energy efficiency, and reduces environmental impact. With strong commercial potential, it encourages eco-friendly habits and benefits global communities through smarter energy use.
