Battery Charger & Maintainer for Car, RV, Tractor - Solar Panel Kit with Intelligent Controller, 25% Efficiency

Feature: 1. 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% 2. 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. 3. More Sturdy: This 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. 4. 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. 5. 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 Clamp/Holder. 6. Widely Applicable: Suitable for any car, lithium ion battery, motorcycle, ship, tractor, all terrain vehicle, agricultural equipment, and a battery charger maintainer for batteries. By using a solar charger, you don't have to worry about the battery running out. 7. Efficient Water Proof: The self dumping trailer solar cell charger adopts high power semi flexible polycrystalline silicon solar panels, which are more efficient, lightweight, sturdy, and easy to store than other products. At the same time, we have upgraded the water proof performance, which is very suitable for outdoor use. 8. LED Charging Indicator Light: Red green dual color indicator light, red indicates receiving sunlight, green indicates connected to battery charging.

• Intelligent & Safe Charging: Features a built-in intelligent controller with fast charging and an internal guard system to prevent overcharging, overvoltage, and short circuits, ensuring safe and efficient battery maintenance.
• High Efficiency & Durable Build: Made with polycrystalline silicon and high-transparency tempered glass for up to 25% energy conversion. The robust, scratch- PET EVA PCB frame is , impact-, and requires no maintenance.
