Does the solar panel must have the exact formula in the output of the charger to charge a cell phone battery?
In my case, the output of the charger to charge a cell phone battery with 3.7 volts is 3.7 volts and 355 mA which equals to 1.3135 watts…
So if I want to charge my cell phone battery thru a solar panel, the solar panel must have 3.7 volts and 355 mA which equals to 1.3135 watts… Is this ok??
How long (hours) this would take??
