OYMSAE 20W 12V Solar Panel Car Battery Charger Portable Waterproof Power Trickle Battery Charger & Maintainer for Car Boat Automotive RV with Cigarette Lighter Plug & Alligator Clip

?[Charge Visualization]The indicator lights can help you understand the charging status: the blue light is on (put in the sun). the red light is on (charging). and the green light is on (charging is complete).A short circuit occurs and all three indicators are off. ?[Intelligent Protection] Built-in charging microprocessor. improved charging algorithm. can provide overvoltage protection. overcharge protection. short circuit protection. etc. It can prevent reverse charging and can be safely used for charging and maintenance of 12V batteries. ?[Higher Conversion Rate]The regular convex points of surface distribution are conducive to the secondary propagation of light. absorb the radiant heat of solar energy to a greater extent. and greatly improve the photoelectric conversion efficiency. ?[Widely Used] The included 3-piece SAE cable kit is plug-and-play.it can be used for cars and 12V batteries. Comes with carabiner and suction cup to meet your different installation needs. Suitable for automobiles. RVs. motorcycles. ships.snowmobile .etc. ?[More Durable] The ETFT material can be waterproof and dustproof. A layer of epoxy board is added as a bottom plate. which is more sturdy (the broken panel will cause the charging efficiency to decrease). You can contact us at any time if you have any questions.[Charge Visualization]The indicator lights can help you understand the charging status: the blue light is on (put in the sun). the red light is on (charging). and the green light is on (charging is complete).A short circuit occurs and all three indicators are off..
