1. A solar panel battery charger is capable of efficiently transforming solar energy into electrical power. However, the weather can significantly affect the output! 2. This solar panel does not have the ability to store energy; it can only generate direct current, with an operating current ranging from 0 to 0.4A.

3. In a well-lit environment, low-power mobile phones can receive emergency charging, but as the battery level increases, charging becomes more challenging due to the product's power limitations. 4. The variability of sunlight causes the electricity produced by the solar panel to fluctuate, resulting in the smartphone not accepting a charge.

Application: This solar panel is suitable for various devices, including portable fans, smartphones, tablets, and other small electronics.

Simple setup and usage: Installing the solar panel is straightforward, eliminating concerns about installation issues. It can be set up in just a few seconds without the need for any tools.
