The sun does not always strike it straight on and we can't count on getting the full peak watts all day. Early in the morning and late at night solar panels have a much reduced output with maximum output near noon. A good rule is you can get the equivalent of about 42% of maximum output per 12 hours of sunlight - less on cloudy days.2. Some devices may not charge directly from this panel due to weather conditions or limitations of your device. If you are having trouble， make sure the panel is in bright sunlight angled directly at the sun.3. It is recommended to use this solar panel together with a rechargeable battery so the power generate by the solar panel can be saved and stored.Package Including:1 x 7W Solar Pack
