How To Make A Solar Power Bank 

Awesome project

Hola amigo un saludo desde Venezuela buen proyecto. Excelente

Nice video! 👍Although I recommend adding safety information and warnings in the video or description... The parts can be dangerous if you don't know what you're doing.

Does it(battery of the device not the cp) have charging automatic cut-off when fully charged?

Awsome

Does the 5v solar panel 1w work?

Nic bro it even supports fast charging

can i use 3 batts and 2 solar panels ?

How to do with another type of power bank module

Ooo

With panel of that size your battery will be charged fully after 3 days
