Direct charging isn’t a problem with these panels as they have USB ports.

Know the Basics: Power Terms

Before choosing a solar panel, you should understand:

• Watt (W): Measures power.
• Volt (V): Measures pressure of electricity.
• Ampere (A): Measures current flow.
• mAh (milliamp-hour): Measures battery capacity.

You might have a phone battery that is 3000 mAh. LED lights usually use between 1 and 5 watts of power.

How to Choose the Right Solar Panel for Your Phone and LED Lights?

To choose the right solar panel for your phone and lights, figure out the total amount of power you need.

• Your LED light uses 3 watts and runs for 5 hours = 15 watt-hours.
• Total = 30 watt-hours per day.

To cover this, you need that which produces 30+ watt-hours daily. A 10-watt solar panel in full sun for 5 hours gives 50 watt-hours. That’s enough.
