Eltronicschool. - Let we continue to make electronic project now. In this time we will show you electronic project on How to Make Our Self Power Bank from Car HP Charging DC to DC Converter. And output of this project we hope you will make your self power bank without must buy power bank from the electronic shop or gadget shop to charge your gadget or HP in everywhere and whenever.

Materials and Tools

Figure 1. Materials and Tools

1. Cutting pliers, 
2. Cable cutters pliers, 
3. Screwdrivers plus and minus, 
4. Desoldering Ion, 
5. Tin, 
6. Battery (rechargeable cultivated), 
7. Box or casing where the contents 4 batteries , 
8. ON / OFF switch, 
9. Terminal cable , 
10. and the last is a tool that is used to make the process charging in the car.

Step-By -Step to Make it

And now please follow the step by step on how to Make Our Self Power Bank from Car HP Charging DC to DC Converter as follow:

1. Prepare tools and materials required for the manufacture of power bank as like in figure 1 above.
2. Once all the equipment is ready, the next step we are ready to make the power of banks, take part which is used for charging the phone in the car, and then unloading and grab the PCB circuit therein, as like the figure 2 below.

3. Then take the PCB contained therein, the PCB is the one that will be used to lower the voltage or DC to DC Converter term, then we are in the setting PCB Casing that we prepared, we can use a glue gun or glue to attach the PCB into the firing casing.
4. The next step then we are ready to do the wiring circuit using additional cables, we connect the blue cable is a cable (+) cable to the red and yellow wires are the cable (-) to the black wire, cable, or the positive red color we associate with the switch ON / OFF, and then we connect the cable to the terminal cable as like the figure 3 below.
