• Intelligent Charging Controller: Built in internal guard system and intelligent fast charging function, combined with solar silicon materials, ensure high conversion rate and stable output, making the energy conversion efficiency of solar panels up to 25%
• Intelligent Internal guard System: The solar cell charger will not damage the battery or cause overcharging. Built in intelligent guard system and blocking diode structure ensure that overvoltage and short circuit will not occur, making charging safer.
• More Sturdy: This 35W solar car battery charger is made of high transparency glass, high strength, impact resist, and snow resist low iron tempered glass. This water proof solar cell charger requires no additional maintenance.
• Scratch Resist Design: The PET EVA PCB frame is more robust than flexible solar panels, so there is no need to worry about solar panel bending. Aluminum alloy material may damage the car paint, but with a PET EVA PCB frame, there is no need to worry about durability.
• Easy To Install And Use: This solar cell maintainer is easy to install and use, simply plug it into a car power outlet (i.e. lighter socket), or directly connect the solar panel to the battery with a clip.
