Charge Visualization The indicator lights clearly show the charging status. Blue indicates exposure to sunlight, red indicates charging, and green indicates a complete charge. If a short circuit occurs, all three lights turn off. Intelligent Protection Builtin charging microprocessor and improved charging algorithm provide overvoltage protection, overcharge protection, and short circuit protection. It ensures safe charging and maintenance of 12V batteries and helps prevent reverse charging. Higher Conversion Rate The solar panel features a regular convex point distribution that improves secondary propagation of light, maximizing solar energy absorption and significantly enhancing photoelectric conversion efficiency. Durable Construction Constructed with waterproof and dustproof PET material and reinforced with an epoxy board bottom plate. This solar charger kit exhibits exceptional durability and remains sturdy even if the panel is broken, sustaining charging efficiency. Use scenarios Outdoor and offgrid charging: ideal for camping, fieldwork, or remote sites where sunlight is available to charge and maintain 12V battery systems. Remote equipment and surveillance: suitable for keeping 12V batteries charged for cameras, sensors, or other batterypowered hardware in uncovered or hardtoaccess locations. Emergency and backup power: useful for vehicles, boats, or other 12V setups needing reliable solar charging and battery maintenance during outages or in remote conditions.
