What is solar power bank?

A solar power bank is a portable device that stores energy from the sun to charge electronic gadgets like smartphones, tablets, and cameras. It contains a photovoltaic panel that converts sunlight into energy, which is then stored in the built-in battery. The charging time of the device depends on the size of the power bank and the intensity of the sunlight. Solar power banks are very useful for people who spend long periods outside or in places without electricity. They can charge multiple devices simultaneously and can be recharged quickly using solar power. They are also eco-friendly as they use clean energy, reducing the carbon footprint. Some solar power banks also come with additional features like waterproof casing, LED light, and a compass, making them useful for outdoor activities like camping and hiking.
