The Mregb YD-819 Solar Power Bank Charger typically takes about 30-40 hours to fully charge via solar power, depending on sunlight conditions. It is important to note that the output power of the solar panel is influenced by factors such as solar irradiance, solar panel temperature, and natural conditions like day and night, season, geographic latitude, and altitude. The maximum power output by the solar panel is achieved when it is facing the sun between 10 am and 3 pm, with an atmospheric mass of AM1.5, light intensity of 1000W/m2, and a temperature of 25°C.
