Full step-by-step tutorial on making your own mobile phone power bank
I believe that many friends are inseparable from their mobile phones. The most troublesome thing is that the mobile phone battery is exhausted, but there is no place to charge it.
In order to avoid the sudden consumption of the power of your mobile phone, you can prepare a mobile phone power bank in advance. It is necessary to carry the power bank with you.
What I share here is a tutorial on recycling waste. It is actually a method of making parts that use AA batteries to charge mobile phones.
Don’t be afraid even if there is a power outage, let’s take a look at how it is made.
Prepare the battery box, voltage stabilizing components, charging cable, AA battery and welding gun in advance.
Cut off one side of the charger and remove the wires.
Use a tool to remove the protective sheath outside the wire.
Take out the voltage stabilizing component and the battery box, weld the red wire of the battery box directly to one of the positive electrodes on both sides of the voltage stabilizing component, and weld the black wire to the negative terminal in the middle.
Also solder the black wire of the charger to the middle side, and the red wire to the remaining side.
Paste the voltage stabilizing component under the battery box, and a battery power bank is completed.
