A solar charger is a device that uses solar energy to charge electronic devices, such as smartphones, tablets, laptops, and other portable gadgets. It typically consists of photovoltaic (solar) panels that convert sunlight into electrical energy, which is then stored in a battery or directly used to charge the device. Solar chargers are an eco-friendly alternative to traditional power sources, especially in outdoor settings where access to electricity may be limited. These chargers are often compact, portable, and designed for use in various environments, such as camping, hiking, or emergency situations. Many solar chargers come with features like water resistance, multiple charging ports, and built-in power banks, making them versatile and reliable tools for staying powered up while on the go. Their efficiency depends on factors like sunlight intensity, the size of the solar panels, and the time of day.
