This Tiny 3.7V Battery Can Power a 220V AC Bulb! | Mini Generator DIY Project

Can a tiny 3.7V battery really light up a 220V AC bulb?
In this amazing DIY science project, I built a mini generator that converts low voltage DC into usable AC power — enough to light up a standard 220V bulb! Watch the full video to see how it works and how you can make it too.

Materials Used:

2x 3.7V Lithium Batteries

DC Motor (High-Speed)

Flywheel/Disc

220V AC Bulb

Switch, Wires & Base

Mini Generator Setup

How It Works:
A 3.7V battery powers the DC motor, spinning a disc that works as a flywheel. This spinning generates electricity using mechanical energy, producing a high enough voltage to light a 220V AC bulb — no inverter, no tricks!

Educational Purpose:
This project is designed for students, DIY hobbyists, and anyone interested in learning the basics of power generation. Ideal for school science fairs, STEM activities, and engineering inspiration.
