Warm reminder: Please charge this solar panel through the socket for at least 6-7 hours before the first use to fully activate it. Please do not use solar energy as the main source of charging. Solar charging is a charging method for emergency use. In daily life, we strongly recommend charging through wall sockets. Please be informed that solar charging is an additional feature. The actual outcome may not be as positive as you expect because the panel size is small, the capacity is large, and the intensity of sunlight cannot be controlled. Thank you for your understanding! In summer, do not place it in high-temperature environments such as beaches, car dashboards or decks. If you want to have two device chargers together (two devices, each with an output of 1A), the charging will be a bit slower, but one device will charge at a high output of 5v/2.1A, so the charging will be faster. The USB cable in the package is only used to charge the solar charger. It is not recommended to charge other devices, as this may reduce charging efficiency due to incompatibility.
