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

You can use really any battery

Take it apart, carefully, and separate the batteries

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.

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.

First charge it a little bit, then use it for your phone :)
