Disclaimer: Love Your RV! received a 200W Lensun Solar Blanket Kit review sample free of charge.
The kit includes a 200-watt semiflexible solar panel array that folds up into a super portable 16"x16" square. It also includes a waterproof EPever 15A MPPT controller, various hookup cables, a canvas carrying bag, and an EPever WiFi data dongle.
I tested its charging power output when flat on the ground and then perpendicular to the ground for the best sun angle. Then I performed a simulated rain test, soaking the system pretty good for several minutes with water. It handled the shower and kept right on charging and dried out within an hour's time.
I found the 200 watts fell short of rated amps and watts. But still pretty good considering its a flexible folding panel and my test environment wasn't optimal. Overall I feel it may be quite useful for campers and RVer where storage space is at a premium. Or folks that want a simple way to attach a solar charging system to their batteries.
