A Solar Power Bank is a type of portable battery that is designed to be charged using solar energy. They are typically small and lightweight, making them easy to carry around, and come in different capacities to provide varying levels of power. Solar Power Banks are often compatible with a range of devices and can be charged using a USB cable or by placing them in direct sunlight. They are ideal for those who spend a lot of time outdoors and need to keep their devices charged without access to a power outlet. Solar Power Banks are also an environmentally friendly option, as they do not require electricity from the grid to charge.
