Introduction: Cheap Hack for Power Banks
Today i will show you how to make a really cheap and easy "hack" for making the capacity of your power bank bigger
Step 1: Find a "not-so-old" Useless Laptop Battery
You can use really any battery
Step 2: Break the Rules!
Take it apart, carefully, and separate the batteries
Step 3: Put the Batteries Together
The positive side of the cells have a "line" on the side, get all the positive sides together, as shown (badly) in the picture.
Do the same with the negative side.
Step 4: Disassemble the Power Bank
Find the positive wire (red) and negative wire (black), and connect the negative side of the batteries to the negative of the power bank, do the same thing with the positive. Tape it all up, and you are ready to go.
Step 5: Test It!
First charge it a little bit, then use it for your phone :)
We have a be nice policy.
Please be positive and constructive.
