Compact and versatile, this 3W 5V USB solar panel is designed for on-the-go charging and DIY power projects. The polysilicon cells convert sunlight into a reliable USB output suitable for charging phones, powering small USB devices, or integrating into portable power banks and DIY generators. Its lightweight panel makes it ideal for travel, camping, or emergency kits where access to mains power is limited.
The simple USB output lets you connect directly to phones or to a battery module for energy storage. Durable construction withstands outdoor use, and the low-profile design fits easily into packs or toolboxes. Because it’s a basic solar charging component, it works best under direct sunlight and can be combined with other modules for enhanced functionality.
