The charger doesn’t work because there’s not enough energy that is coming through the solar panel.
The only thing that is successful is that it produces energy but not enough. I think next time I need to add another solar panel so it can produce enough energy so it can charge the phone. If this product works It definitely can help a lot of people with their phones. For example, when your phone’s battery capacity is under %90 it might lose a lot of battery very quickly throughout the day, so this is product can help peoples phone’s lasting for a day.
