The solar power bank itself can be charged via power outlet(micro usb and type C input port) and sunlight. Yet its recommended to take the solar charging feature as the emergency back-up solution instead of main power sources. It's difficult to produce intensive power via sunlight due to sunlight intensity and panel conversion rate.
This 30000 mAh power bank especially for outdoor enthusiasts. More than portable solar power bank but qi portable charger as well compatible with iPhone XR/ XR MAX/ XS/ X/ 8/ 8plus, Samsung Galaxy S9/S9plus S8/S8plus and all qi-enabled devices. Truly cable-free and tangle-free.
Battery Capacity: 25001-30000mAh
