Components to make Solar Charger cum Power bank
List of all components that you needed to make solar power bank.
1. DC to DC Converter
- Buy a 3V to 5V 1A Module Step Up Converter Boost USB Charger. It regulates and stabilizes output voltage and current. I bought it from Amazon. I’m a great fan of Amazon where you can search and buy each and every Components that you need to make projects like this. My readers aren’t only from India. So I cannot provide link to a specific product link to Amazon. If you have any doubts about this product just drop your comments below. I’m very happy to help you. You can trust Amazon because they provide quality components. We can track our product anytime from your smartphone. That’s why I love Amazon.

2. AA Size Rechargeable Batteries
Buy four AA Size 1.2 V 1600 mAh Rechargeable batteries. You can use any 5V 1600 mAh Battery to make this project.

Consider your smartphone is running out of power and you forgot to recharge the power bank. What would you do? Obviously, you can use a solar panel to charge your smartphone. What would you do If it was a cloudy day or you are facing this problem at night? (hope It won’t). Here comes the importance of placing battery outside using a battery connector. Therefore you can buy some non-rechargeable batteries and connect them to the battery connector and recharge your smartphone. That’s it.
3. Diodes, Battery connector, Plain PCB Wires, Switch
Buy 2 IN4007Diodes a battery connector, a piece of plain PCB from your favorite hardware/electronics shoppe. Since these components are locally available I don’t recommend Amazon here. You can use a plain Pcb to make the circuit compact. At the same time, you can simply connect all the components directly using a soldering Iron.
