Review on High-Efficiency 20W 12V Solar Panel Battery Charger Kit | 20 Watt 12 Volt Monocrystalline PV 🔋 Module for Car, RV, Marine, Boat, Caravan Off-Grid System | Includes 10A Charge Controller + Extension Cable by Derrick Bellando

I had trouble understanding the instructions. This may partly be because the print was tiny and very difficult to see. My next order from Revane will be a magnifying glass. But for the most part, it was pretty easy to figure out. I liked the control module that shows voltage etc. I added some connectors so I could separate the wires from the solar panel and the output to the battery. It would have been nice if they already did that, but for $40 it didn't really matter. It keeps my extra battery in my RV well charged. I would buy this again.
