6W is the maximum power generation achieved by a one square meter solar panel under strong light experimental conditions (one square meter of monocrystalline silicon solar energy is 1000W). The size of this solar panel is 0.088x0.142 square meters. Under sufficient conditions, the power generation of this size is approximately 0-6W per hour, with a USB output of 0-5V and a current of 0-0.4A. It is not suitable for direct use on high-power mobile phones. Suitable for low-power products, solar panels need to be used in direct sunlight at 45 degrees Celsius. Please refer to the manual for details. The specific charging capacity may vary depending on the region and weather. Please refer to the actual situation for details
