Reasons Why Your Solar Charger Isn’t Charging Your Phone

The reasons why your solar charger is not charging your phone are detailed below:
1. Insufficient sunlight for the charger
One of the most common reasons why your solar charger isn’t charging your phone may be due to insufficient sunlight. Since the charger is dependent on sunlight for optimal performance, if the sunlight intensity is not enough to help the charger generate electricity, the charger may not work. As you may have known, cloudy weather, shadows, etc. may reduce the efficiency of a solar charger.
2. Obstruction of Solar Panels on the Charger
When there is dirt, dust, or debris on the surface of the charger’s solar panel, it may also stop the charger from working because it won’t be able to trap enough sunlight that would generate electricity due to obstruction.
3. Low-Quality Solar Charger
Another common reason why your solar charger may not charge your phone is when the charge is of low quality. Since not all the solar chargers are of high quality, if you go for some low-cost solar chargers, they may not be durable, hence not being able to power your phone.
4. Incompatible or faulty charging cables
If the cable that you’re using to charge your phone is incompatible or faulty, the solar charger may not be able to charge your device.
5. Faulty Phone Battery
If your phone’s battery is damaged or defective, it may not be able to hold a charge effectively. In fact, a faulty phone battery may not hold charge at all, and in some circumstances, it may even be discharging.
6. Device overheating
Since solar charges are often used outdoors to charge phones, devices may become overheated due to direct sunlight. If this happens, the phones may stop charging, especially those with in-built mechanisms to prevent charging when the device is too hot.
7. Power Output Issues
Since different solar chargers have different capacities and power outputs, the charger may not be able to charge your phone if the power output from it is lower than what your phone requires. When there are power output issues, the charger may not charge your phone efficiently.
