Features

  • [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 PET 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.

    • Simple and effective setup.
Color: White Size: 5W
The installation instructions are good and easy to follow. Mounted on top of the trailer kit, it charges the deep cycle battery and performs as expected. The whole is very stable and does not move even in high winds.

    • Keeps 60 AH Marine battery topped off
Color: Black Size: 20W
Small size for 20W for 1.6 A output at 12V, perfect for my 60 AH boat battery maintenance. Quality appears good. Comes with all connections you need. I used the battery clips to make sure it worked first to top off then maintain battery then I installed the ring clips. I added a fuse for remote chance of a shorted solar panel causing a catastrophic battery failure. ... show more

    • Must read description
Color: Black Size: 10W
Output power on this is 18 volts. This can damage a 12 volt battery. I returned it for a 12 volt output model and that one works great

    • Stopped working after 2 months (Or so I thought) [UPDATED REVIEW]
Color: Black Size: 30W
Original Review: At first I really liked the panel, I have a Bluetooth adapter that reads battery voltage and I could see the charge go up if I sat there for a few seconds. I was checking voltage regularly (every 2 or 3 days) to make sure it was keeping my battery at the properly charged, which it was. So when I finally decided to trust this and not be checking it so often, it stops working. Now I have a dead battery and will have to pay to have it replaced. Not happy. Updated Review: Let me start by saying that the reason my battery drained was not this solar panel's fault. Turns out the Hands-Free Link module in my car had gone bad and was draining the battery even when the car was off. Once that was found to be the issue, thanks to a friend that has the same car I do and coincidentally started having the same battery drain issue too, he told me what was causing and how to get to it to unplug it to test if my HFL module was draining the battery. After the HFL module was unplugged I then though to take this solar panel out from storage and check, I had not used it since I labeled it as "bad" but never got to throw it away since I thought it did put out some power just not enough for my car. Well now I can say that my car can sit indefinitely, the battery will not die anymore and has not gone bellow 12.3 volts even after 3 weeks of the car not being used. ... show more

    • Working well
Color: Black Size: 10W
I'm using it to charge a 120AH Li battery running my electric fence. It keeps the battery charged and so far, no problems.

These things are great for keeping the toys topped off. However in my case the first one I bought in October of 2023 has started to deteriorate. Here we are on June 17th 2024, so 8 months later in the Tampa, Florida sun the clearcoat coating on the top of the panel has started to deteriorate. I'll likely just remove this with some glass etchant and spray some new clear on it. Thing still works fine, I have two others that are newer and will see how those hold up. So three stars, absolutely functional, but is gonna need some maintenance to keep functioning well in a relatively short term. ... show more
