DIY solar mobile charger
It is very easy way to make a solar mobile charger
We need solar panel , IC7805 , OTG cable , college bag and other things.
7805 IC you can buy from online or near shop.
Solar panel gives 9.0V maximum but mobile phone needs 5.0V. so 7805 IC convert 9v to 5v.
OTG cable work as a USB port
The most important thing is you can attach solar panel with your college bag.
When we go to any trip then you can charge your mobile phone very easy
