Is solar phone charger really useful

- Jun 12, 2017-

   Like what we said before that solar panel is composed of PCB, solar cell, EVA and PET. The voltage of each complete cell or small cutting cell is 0.5 or 0.55V. For charging cell phones, we need to make solar panels with at least 5V or higher voltage. So we will connect 10pcs or 12 pcs solar cells in serial. If so, we can get around 2A output current from a 13.2W folding solar phone charger.

   Power banks are widely used in our dairly life. Normally the output of power banks are 5V 1A or 5V 2A. Compared to power banks, solar phone charger can also reach 5V 1A or 5V 2A output, which means it can charge your phones naturally.
