A solar charger can be used in many situations. The best time to use it is when you are outdoors with good sunlight. For example, during hiking or camping trips, a solar charger can keep your phone and flashlight ready at all times. Travelers also find it useful while waiting at airports, train stations, or bus stops. Instead of searching for a plug, they can simply place the charger in the sun and power their gadgets. Solar chargers are very helpful in emergency situations too. During natural disasters, power cuts, or storms, electricity may not be available. In such cases, a solar charger becomes a lifesaver.
