Review on 🔆 5-Watt Solar Battery Trickle Charger by Sunforce - Black by Andrew Enriquez

Used for 2 seasons to service house/chassis batteries while in storage - seemed to work fine but at the end of the 2nd winter a plate died. I opened the supposedly sealed control cabinet on the back and found that water had gotten in and the connection to the panel was open (breakage in the panel - not repairable). Another panel, which oddly still worked, also showed moisture intrusion both into the electrical enclosure and the panel itself (discolored in one corner). Even if it still worked, I wouldn't trust it for another season. No matter how much they cost, they should have lasted longer.
