Dumsor is here once again. I hope you remember those days you can go for days without your gadgets! Powerbanks are real saviours when Dumsor becomes so intense. I will show you how to make a power bank in 5 minutes in this tutorial. This are the stuffs you might need:
1. Lipo charger module TP4056: Its role is to convert 5V fto 4.2V for charging the Lipo batteries
- Two or more Lipo batteries. (you can salvage from an old laptop battery). I used two 2500mah Batteries I grabbed from Aliexpress
3. 5V boost converter module. This converts 3.7V from the Lipo batteries back to 5V for charging your phone
I first connected the two batteries in parallel. This makes my power bank to have a capacity of 5000mah
I did same for the TP4056 lipo charger module. This are the final results.
