SOLPERK 5W Solar Panel, Battery Trickle Charger and Maintainer



  • 💡[High-efficiency solar panel] Solar battery charger is to convert sunlight into electric energy and charges the battery. The more the sunlight is, the higher the charging efficiency is. The charger will generate current to trickle charge the battery that prevent the loss current of the battery in storage or standby process.
  • 💡[Charger and Maintenance Device] This product is a solar battery charger and maintainer. It can safely charge and maintain 12V batteries such as Wet, Gel, MF, EFB and AGM. In addition, it is also suitable for any car, motorcycle, ship, tractor, RV, Powersports, snowmobiles, trucks, etc,It’s the solar powered battery tender for many cars.
  • 💡[Prevent reverse charging] – It has built-in blocking diode to prevent reverse charging and battery reverse discharging. Blue indicator lights up when charging.
  • 💡[More durable] Weatherproof solar car battery charger,covered with a more durable ABS plastic case.,it’s windproof and rainproof, but it can’t be immersed in water.
  • 💡[Easy to install] The product is light and easy to install for inexperienced people. The interfaces are plug-and-play. The kit needs no extra maintenance, no electricity. It’s energy conservation and environmental protection.

    This product has the following characteristics:

    1. With high efficiency Polycrystalline solar cell, you will get greater power efficiency even though the panel is smaller than a traditional model.
    2. It has built-in reverse diode. No matter during the day or at night, it will not waste any battery power.
    3. It is convenient to charge. So long as there is sunshine, the battery can be charged.
    4. It’s convenient to connect. There is no need to extend the line. And it works under the safe voltage of human body.
    5.The surface of the glass material is easy to clean.


    1.Before connecting the wires, please separate the red and black clamps to avoid collision and result in short circuit.
    2. This product is a battery maintainer, it can not be used as a charger!
    3. The more sunshine there is, the better the charging effect will be.
    4. If conditions permit, place solar panels directly into the sunlight to maximize efficiency.
    5.If the car is charged, do not use it when starting the car and driving to avoid the surge of the car engine may damaging the solar charger.
