Review on 🔆 Sun Energise 20W Waterproof Solar Battery Charger Pro with MPPT Charge Controller - 3-Stage Charging - Trickle Charger Panel with Adjustable Mount Brackets + SAE Cable Kits - 12V by Henry Brown

There is no electricity where I park my trailer. It is enough to push and pull the slider several times to drain the battery. This charger keeps it well charged and very reliable. When I plugged it in for the first time, it showed that it was charging. I don't know how low my battery is but when I came back to check it. The battery was fully charged. Texas just experienced a week-long severe winter storm. Below zero and more snow than in years. We went from -4*F to 80*F in a week. The charger shows no signs of damage or loss of functionality. I would recommend this device.
