Some weatherproof devices can be charged with solar power. These devices often come with a solar panel that can be attached to the device to charge it using sunlight. This is a useful feature for outdoor activities where access to electricity is limited. It is important to note that the charging time and efficiency may vary depending on the weather conditions and the strength of the sunlight. However, with the advancement of solar technology, many weatherproof devices are becoming more efficient and can charge quickly even in low light conditions. Overall, having the option to charge a weatherproof device with solar power is a convenient and eco-friendly feature.
