ECO-WORTHY 7.5W Solar Car Battery Charger Maintainer

Upgraded Smart Charger Controller

The built-in smart charger controller in the solar panel offers six essential protection functions: over-temperature protection, reverse discharge prevention, short circuit prevention, reverse polarity prevention, and overcharging protection. Additionally, the integral blocking diode effectively blocks reverse current flow, ensuring optimal energy transfer.

Real-time Monitoring

Accompanied by a trio of LED indicators, the system provides instant feedback: half lit indicates charging, blinking signifies full charge, and off means no input or disconnected battery. Once fully charged, it automatically disconnects to prevent overcharging, ensuring your battery's longevity.

Stronger and More Durable

After rigorous testing, the A+ grade monocrystalline silicon wafers boast a conversion efficiency of up to 23%, maintaining a consistent 7.5W output. The weather-resistant glass fiber surface offers robust protection against environmental factors, with IP64 waterproofing and UV protection.
