This solar power bank by X-DNENG is multifunctional and compact. It has a built-in lithium-ion battery of 12000mAh which can be charged either by solar power or by the main outlet using the USB charging cable provided. When the solar panel is exposed to sunlight a green light will turn on, meaning the power bank is charging. However, charging by sunlight is slow and it is used only as a backup charging. The main charging is done by connecting the power bank to a power supply. When all four blue LED lights turn on it means the power bank is fully charged. There is a power button which when pressed shows the level of charge for the battery. The power bank has an LED light torch emitting a powerful light which can be used in an emergency. There are two USB outputs of 5V /1A and 5V/2.1 A hence the charging is fast. The power bank comes with a carabiner to attach it to a backpack or tent. It works with any type of mobile phones and tablets and also with GoPro camera and kindle. It is a very useful device to use when camping, hiking and in general for travel and for any outdoor activities.
