SolarBank

This is powerbank with fotovoltaic panel. It's made from the scrap in my desk - I decided to give them second life :-)

If you would like to made it, you will need:

1. 114 x 84,5 fotovoltaic panel
2. LED colimator fi 16,5 mm
3. 2 x round button fi 8.5 mm
4. Voltmeter (23mm x 10mm - see picture)
5. Powerbank module 2 X USB 2A 5V 18650 (see picture)
6. 1 x microswitch
7. Voltage regulator for charging 18650 battery
8. 6 x 18650 battery
9. 4 x 3mm LED
10. 1 x standard diode for protection
11. On/off switch for switching between voltmeter and charging from solar

SolarBank case can be printed without any supports - supports are included in the project, just brake it out after printing.

Enjoy!
