How do I charge my phone with the SOLAR-3.5?
Connect the USB-A cable to your device and place the panel under direct sunlight. For optimal charging, adjust the panel angle to face the sun.
How long does it take to charge a smartphone?
The charging time depends on the battery capacity and sunlight intensity. Typically, a 3000mAh phone battery can be fully charged in approximately 8-10 hours of direct sunlight.
Can I use the SOLAR-3.5 indoors?

The integrated LED indicator lights up when the panel is receiving sufficient sunlight. A blinking LED indicates active charging, while a solid LED may indicate standby.
Can I connect the panel directly to my phone?
Yes, the panel has a standard USB-A output. However, we recommend using a power bank as a buffer to regulate voltage for sensitive devices.
What should I do if the LED does not light up?
Ensure the panel is exposed to strong sunlight and the USB cable is properly connected. If the issue persists, clean the solar panel surface and try again.
Can I replace the USB cable?
The cable is permanently attached to the panel for weather resistance. If damaged, the unit must be repaired by a qualified technician.
How do I clean the solar panel?
Use a soft, damp cloth to gently wipe the surface. Do not use solvents or abrasive materials that could scratch the glass.
