Review on 🌞 Efficient 17W Solar Battery Charger - Weather Resistant and Mountable - 12V by Ryan Sandell

We have an RV / camper and if it is stored for a while the battery will sometimes drain completely as the carbon monoxide sensor will still work when disconnected and the battery can drain over time. It hurts when I stop to check, pull out the chutes, etc. Anyway, I hooked this thing up and just hung it on the front of the trailer or the prop is on top of the hitch. It's not permanent and I'll remove it during shipping. The battery seems to last, there were no problems. He seems well built and ready to fail.
