In this fast-paced timelapse, I take a dead laptop battery and give it a second life by transforming it into a portable flashlight and USB power bank! ♻️
Using salvaged lithium cells, a few basic components, and some creativity, I build a useful device perfect for emergencies, outdoor use, or as a backup power source.
🧰 What You’ll See in This Video:
✅ Disassembling a broken slim laptop battery ✅ Connecting 3 lithium cells in parallel ✅ Using a USB power bank module + DC-DC boost converter ✅ Mounting all parts inside custom-cut plexiglass ✅ Testing the power output and LED flashlight ✅ Real-world use cases (backup lighting, off-grid charging)
📦 Parts Used:
3x 3.7V lithium-ion cells (from old laptop battery)
Power bank USB module (salvaged from a broken charger)
DC-DC boost converter (3.7V to 12V)
12V LED strip
Plexiglass panel, screws & nuts
Basic soldering tools
👉 A great example of how e-waste can be turned into something practical!
