Product Details
- SUNAPEX 20 watt solar trickle charger is made of high quality monocrystalline silicon solar chip cells, with a solar charging conversion efficiency of up to 30%, mainly used to maintain the 12V battery and trickle charge the 12 volt battery to extend the life of the battery throughout the year segment. With built-in intelligent controller, this 20W solar battery charger provides full protection for all types of 12V batteries from overcharge, over-voltage, anti-reverse charge, over discharge, short circuit, etc. Perfect solar trickle charger for boat, car and rv battery. Different from other products, we added a layer of PCB as the bottom plate of our 12 volt solar powered battery charger, which will make this solar panel charger more durable and stronger. And we using thicker wires and insulated alligator clips with plastic sleeves will make it more durable. SUNAPEX portable solar battery maintainer is IP67 waterproof, which can protect it from rain and snow, even if you forget to store it, you don't have to fear that it has been damaged. What you need to pay attention to is that you need to place the solar panel charger at an angle, and not allow the controller on the back of the panel to be submerged in water for a long time.
