Portable solar panels are compact and lightweight solar energy systems designed for easy transport and use in various locations. They convert sunlight into electricity, making them ideal for outdoor activities like camping, hiking, or road trips. These panels can charge devices such as smartphones, laptops, and batteries, providing a renewable energy source when traditional power is unavailable. Many portable solar panels come with built-in features like USB ports and foldable designs for convenience. They are often made from durable materials to withstand outdoor conditions. Popular brands include Renogy and Goal Zero, which offer a range of options to suit different power needs.
