.Attach the battery backup(I'm using Mi Battery Backup) to the micro usb.
2.Put the setup into your backpack..You can also use a tiny box to encase the charge controller. Now insert the usb into the power supply and charge your device while you travel and walk.
Step 3: Connecting to Charger
Remove the cover of old USB car charger
Solder the wires (positive and negative) to the charger
Use a connector to connect the wires to old battery
Use the USB cord to connect to the USB port to charge your mobile phone

The disadvantage of this method is that until you have high intensity of sunlight it would not work.
