Perfect Solar Charger for My Boat Battery

The setup was easy, and the included controller worked great. The build quality feels solid and durable, and the panel handled outdoor conditions well. This is a reliable and affordable solution for keeping a battery maintained on the water. Highly recommend it

Worth while little salar panel
I use this to charge my homemade power generator. I have the charge controller installed in a 30-caliber ammo can. So far it has worked great. Hard to get a full 20w as I’ve never had full sun yet, but it has charged my little agm battery regardless. Having extra power while camping is great. The plug ins are a little cheap, but the sand is really nice. The kit is plug and play. Note that the solar controller does not monitor battery usage, so you can drain your battery dead with this system. Make sure that works for your use.

The upgraded controller works smoothly and prevents overcharging, so I never have to worry about battery damage. The adjustable mounting bracket makes it super easy to position the panel for maximum sunlight, and the materials feel sturdy and weather-resistant. I love how simple the installation was — it only took a few minutes to set everything up. The panel performs well even on cloudy days, giving a steady trickle charge that maintains my batteries perfectly. It’s compact, reliable, and perfect for off-grid or storage use.

I purchased with the hope that this charger would keep my car battery charged over several months while I was away from home. I have now used it twice, both for two month periods where the car was parked under a carport. Even though the charger was not in full sun, it has worked and the battery has been fully charged each time on my return.
