🔋 Bringing a Dead Powerbank Back to Life!
In this DIY project, I repair a small, non-working powerbank by replacing its dead battery with recycled lithium-ion cells recovered from disposable vapes.
Instead of throwing away the powerbank, I decided to give it a second life using 8 recycled vape batteries, each rated at 400 mAh. Connected in parallel, they provide a combined nominal capacity of 3200 mAh.
It's a simple electronics recycling project that turns discarded batteries into something useful again! ♻️

- 🔧 Opening the powerbank and removing the faulty battery.
- 🔋 Recovering and preparing lithium-ion cells from disposable vapes.
- ⚡ Connecting 8 cells in parallel to build a new battery pack.
- 🔥 Soldering the connections and fitting everything inside the original case.
- 📱 Testing the repaired powerbank by charging a smartphone.
- ✅ Checking the final result – a working 3200 mAh powerbank!
♻️ Final Result
After approximately 20 minutes of work, the dead powerbank is working again!
By reusing 8 discarded vape batteries, I managed to save an electronic device from becoming e-waste and created a compact emergency charger.
A small recycling project, but another piece of electronics saved from the trash!
⚠️ Safety note: Lithium-ion cells recovered from disposable vapes must be carefully inspected before reuse. Avoid damaged, swollen, leaking or overheated cells. Use appropriate battery protection and ensure all parallel-connected cells have matching chemistry, voltage and condition.
