2.5W Amorphous Silicon Solar Panel Battery Maintainer - 16V Portable Solar Charger with PVC Frame for 12V Vehicle Batteries

["High-Efficiency Amorphous Silicon Solar Panel Equipped with non-silicon solar panel core and PVC outer frame, this solar charger features excellent low-light response and low temperature coefficient. It can stably generate power even on cloudy days, effectively compensating for the self-discharge of 12V batteries and maintaining battery activity.","Stable Power Output for 12V Battery Systems With a maximum power of 2.5W, operating voltage of 16V, open-circuit voltage of 22.5V, and operating current of 0.15A, this maintainer provides gentle \"trickle charging\" for 12V lead-acid, AGM and other starting batteries. It won't cause overcharging and is suitable for long-term battery maintenance.","Durable & Waterproof Design The PVC-wrapped panel and IP64 waterproof and dustproof structure ensure resistance to outdoor exposure such as sun exposure and rain. The lightweight and slim design (thickness only 15mm/0.59 inches) is easy to carry and install, perfect for mobile use in various scenarios.","Safe & Convenient Connection Built-in anti-reverse flow diode prevents reverse discharge of batteries to the solar panel at night, ensuring zero energy loss. Equipped with color-coded alligator clips (red for positive, black for negative) and SAE quick-connect interface, installation and disassembly are quick and hassle-free.","Wide Application Ideal for maintaining 12V batteries of cars, trucks, motorcycles, RVs, yachts, ATVs and other vehicles/equipment. Especially suitable for long-term parked vehicles, seasonal machinery and off-grid devices, effectively extending battery life and avoiding power failure during emergencies."]
