Review on ⚡ WindyNation 10A 12V Solar Charge Controller: Waterproof, LED Charging & Load Indicators by Robert Ryokan

I use it to keep the battery fully charged on my pontoon boat. I have a small solar panel (100 watts) mounted on the back of my pontoon that keeps my battery fully charged even when we are out on the lake all day, including a stereo with amps ranging from 2 to 400 watts. I was worried that if the boat didn't start I would run out of battery and get stuck. That's no problem now. I have this because it is waterproof and I have used it on a boat. It's very limited but works great for a very small system.
