A solar charger is a device consisting of small solar panels that convert solar energy into electricity. This can be used to power electronic devices like smartphones, tablets and other devices. You can also use it to charge a battery pack if you wish to combine the two.
A solar charger is usually portable and needs to be put in sunlight to be able to charge. Once there is sunlight, you have a limitless supply of electricity. As it is clean energy, it doesn’t have a carbon footprint.
