Review on 🔆 Efficient 3.5W Waterproof Solar Panel Charger for Feeder with Mounting Bracket - Sumind Solar Power Battery Charger (6V) by David Elam

First off, I would like to address the reviews that said they ordered a 6 volt panel and it turned out to be 12 volt+. Yes, if you check the panel voltage on an open circuit with no load it will read 12 volts or more in direct sunlight. I registered up to 13.3 volts. But when you connect to the load, i.e. to the battery, it drops to about 6.5 volts. I've included photos and a short video showing how I connected and charged it versus no load. I use it to charge 6 volt batteries as pictured which I also bought from Revain. As you can see, when the solar panel is connected to a load, the state of charge is about 6.5 volts. It appears to be well built and will do the job I bought it for. So far so good, but I've only had it for a few days.
