## Customer Reviews

### ⭐⭐⭐⭐⭐ It works well, but you must use it correctly
*by T***B on August 20, 2022*

I bought this a couple of years ago. I mounted it on top of my propane bottle cover on my travel trailer. I use it to maintain my trailer battery when it is in storage. It does a great job. In this application you must disconnect the solar cell from the battery if there is another source charging the battery. When you tow your travel trailer, the tow vehicle provides charging voltage to the trailer battery. You need to disconnect the solar cell from the battery. Also, when you are at a campsite and hooked up to 110 volts, you must disconnect the solar cell.A few weeks ago, I found my battery dead and no light on the solar cell. So, I ordered a new solar cell identical to the one I had. In the process of taking the old one off, I discovered some connection issues. I cleaned all of the battery connections and the old one works fine, and I have spare one still in the box. Yes, I decide to keep It.

### ⭐⭐⭐⭐⭐ Keeps mower battery charged
*by O***L on October 23, 2022*

I use the solar powered charger to maintain my zero-turn mower battery in the off season. The mower is stored in a utility building and I'm able to hang the solar panel outside where it gets plenty of sunshine and it maintains the 12v battery. No issues so far. Mission accomplished. I have also used this solar charger plugged into the 12-volt accessory plug in my car while I disconnect and replace the battery to keep the car memory intact and eliminate having to re-program the car. Make sure the sun is shining when doing this and you will be okay.

### ⭐⭐⭐⭐ Good trickle charger
*by J***N on September 6, 2020*

As long as you have it in the sun, does what it says. However, I would have thought after being in the sun for 2 weeks it would have charged my marine battery, but nope. Oh well, maybe battery too far gone. Going to try different charger that I have for my garage and take to lake to verify.
