Usage Guidelines

1. Avoid Obstruction

Ensure the solar panel surface remains unobstructed to maximize charging efficiency. Even partial shading may significantly reduce power generation.

2. Waterproof Precautions

While solar panels have basic water-resistant properties, protect the backpack and charging ports from heavy rain to prevent water damage

3.Prevent gver-Bending.

Excessive bending may damage internal solar cells and circuits, reducing performance and lifespan.

4. outdoor charging tips

Keep solar panels unshaded during charging, obstructions drastically lower power output and charging speed.

Temperature rise in solar cells under direct sunlightis normal and expected.

5.Environmental Factors


Charging performance depends on:

. Sun angle (optimal when panels are perpendcular to sunlight)

· Light intensity (higher = faster charging)

. Ambient temperature

. Obstructions

Do NOT expose phones/power banks to direct sunlight to prevent overheating damage.


Note:

All performance metrics are laboratory-tested. Real-world results may vary due to environmental conditions.
