Kind note: 1.Take 5V 2A and above Wall charger as daily power sources, please. DC5V/1A is not enough to input this power bank normally, it will be more than 3 times slower. 2.The solar charging results may not be as positive as you might expect due to the small size of the solar panel on this device,it's high battery capacity and uncontrollable sunlight intensity causes long charging times when using solar as the main charging method. It takes 6-8 hours to solar charging 5-10% of the battery, which is designed to make emergency phone calls for outdoor activities. 3. For safety, do not leave the PD powerbank in conditions unsuitable for human beings (like be airtight car under strong sunlight (high temperature) without cooling air).Do not make charge while charging itself.
