Solar chargers are useful in many situations. For example, if you love traveling or camping, a solar charger can be your best friend. When you are in the mountains, on the beach, or in the forest, there are no plugs around. But the sun is always there to help you. They are also very helpful in emergencies. Imagine a power cut during a storm or flood. In such times, a solar charger can keep your phone alive, so you can contact family or emergency services. This is why many people keep one in their emergency kit.
