The time it takes to fully charge the QiSa YD-820W Solar Charger 38800mAh Solar Power Bank using solar energy can vary depending on several factors. The charging time will be influenced by the intensity of sunlight, the angle and position of the solar panel, and the current battery level of the power bank. On average, a full day of solar charging will only yield around a tenth of a full charge. It's important to note that the solar panel's capacity is not as powerful as the battery, which is why it takes longer to charge via solar energy. For a quicker charge, it is recommended to use the USB input with a charging head that is higher than 5V2A. This can fully charge the power bank in approximately 8 to 9 hours when starting from an empty battery.
