Portable solar panels are small, lightweight items that grant energy access while on the go. Often, charge controllers are built into the device, allowing it to interface easily with batteries, and hubs, and even connect to devices using USB ports. Some models use thin film or small monocrystalline cells and can be folded for added convenience. Perfect for hiking or camping, or serving as backup during emergencies, the panels make it easy to sustainably power small electronics, charge batteries, and satisfy energy requirements in isolated regions
