Specification: Output interface: 3 USB Ports Input interface: Micro USB, Type-C Battery type: polymer lithium-ion battery Protection: low voltage protection, overcharge protection, short circuit protection, over-discharge protection LED lighting: Yes Solar power: 1.5W MICRO input: 5V / 2.1A TYPE-C input: 5V / 2A USB1/2 output: 5V / 2A Wireless charging output: 5W Capacity: 20000mAh Material: ABS + TPU Note: Please charge under strong light, do not charge on cloudy days or in places separated by the glass(such as windows or cars). Solar charging is designed for emergencies. Because the size of solar panels and the intensity of sunlight are not the main sources of charging, It may take 21 hours to fully charge under the strongest light (7-8 hours of sunlight per day). So we strongly recommend charging the solar charger through an adapter or computer, which only takes a few hours. Under normal circumstances, charging under strong light for 5 hours can reach 25% of the power, so only the first indicator light is on.
