Car Battery Solar Charger, 20W 12V Portable Solar Power Car Battery Charger Solar Battery Charger Maintainer Panel Charging Kit with Controller for Automotive Boat

HIGH EFFICIENCY: The intelligent charging controller is equippedCwith an internCr silicon materials, ensures a high conversion rate and stable output, making the energy conversion efficiency of the solar panel as high as 25%
INTELLIGENT PROTECTING: The solar cell charger will not damage the battery or cause overcharging. The built in intelligent protecting system and blocking diode structure ensure that overvoltage and short circuit will not occur, making charging safer
STURDY MATERIAL: This 20W solar car battery charger is made of high transparency glass, low iron tempered glass with high strength, impact prevention, wind and snow prevention. This water proof solar cell charger requires no additional maintenance
PREVENT SCRATCH FRAME: The PET, EVA, PCB frame is stronger than flexible solar panels, so there is no need to worry about the solar panels 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 maintenance device is simple to install and convenient to use. Just plug into a car power socket(i.e. a cigar lighter socket), or directly connect the solar panel to the battery with a crocodile clamp
