### ⭐⭐⭐⭐ 







  
  
    Keeps battery topped off
  

*by D***S on Reviewed in the United States on January 16, 2023*

Put this on my starter boat battery so it stays topped off between use. Battery is always at full charge when I use this, so I have permanently put a plug in wire on battery. I plug in, put cover on boat and strap this maintainer onto the top of cover as wire is long enough. When I use boat, I take the cover off and unplug the maintainer as part of the, "ready for water" process. So far, so good. There is a hole in all 4 corners so bungies works great for tie down of maintainer to cover straps. Don't know if will charge a battery but not my purpose.

### ⭐⭐⭐⭐⭐ 







  
  
    Simple and effective.
  

*by M***C on Reviewed in the United States on December 24, 2022*

This solar panel is easy to hook up with multiple different connection options. The supplied wire is not long enough for my particular application but that is easily fixed. I currently have it hooked up to a charge port instead of a direct battery connection. Once I get the wires extended it will be hooked up directly to the battery via the supplied connection adapter. It should be long enough for most vehicles.It keeps the battery from getting discharged on my vehicle. It is currently installed on my Expedition which usually stays in the driveway and only used for hauling. The battery kept getting drained down due to not driving the vehicle on a regular basis. This is far more practical than burning fuel just to keep the battery charged.The install was very simple with the supplied suction cups. I do intend to mount it more securely to the dash in the near future.The size lends itself well to a windshield mounted application and does not cause a visibility problem.I highly recommend this for anyone who has a modern vehicle that sits for long periods of time.

    A Power House
  

*by E***Y on Reviewed in the United States on January 22, 2023*

I had the 10W model but upgraded to this 20W because my car doesn’t get that much direct sun this time of year due to the sun’s angle. The increase wattage definitely made a difference, even on a cloudy days. Can’t wait to see how it performs later in the year when the days are longer with the sun directly overhead.
