Review: Great way to keep battery topped off - This is the second one I purchased, they work as expected keeping the battery topped off.
Review: It works! - Something drains the battery in my truck. If I don't drive it for a week, it will be dead. I don't have time to hunt down the drain so I purchased this, as I don't have any outlets near where I park it. 1 week later my truck starts right up. It has been cloudy and a few days it was covered in snow and this still kept the battery topped off. I am super impressed! My one complaint is that the solar panel does not disconnect from the cord at the solar panel. Not a big deal, but I have to open the hood to disconnect it.

### ⭐⭐⭐⭐⭐ Great way to keep battery topped off

### ⭐⭐⭐⭐ Great solar charger, water and weather proof so so
*by C***Y on March 19, 2023*

Great solar charger for the cost. For the first 6-9 months in the weather it works as designed but after about the 9 month mark the solar charger starts to loose the ability to push a full 4.5-5 watts. After about a year I was only seeing 1.75 watts. But for the price and the durability I have replaced them with the same brand every year. 4 years in a row and they are still my goto. The only manufacturing upgrade I could recommend is some type of sealer around the plastic and the top of the panel. Over time I believe water finds a way in and starts to cause issues with the board inside.
