Review on 🔋 DuraVolt Fifth Wheel & Travel Trailer (Class B&C RV) - Ultra-strong Magnetic 12V Battery Kit for Easy Plug & Play Installation with No Prior Experience Needed by Gordie Johnson

I ordered one of these in October to keep the batteries in my horse cart charged. ! Attached magnets hold it securely to the gooseneck, and while the upright position isn't optimal for catching rays, the trailer's skin and roof are aluminum (which limits my options). I also used this panel to keep my farm truck (diesel) batteries happy at night when it got cold. I usually have to keep the engine block heater on all winter to keep the batteries from dying, but this panel does the job without running a 50-foot wire. I love it so much I just ordered a second one to keep one on each. :-) Oh, and they answer the phone if you call with questions (that's great customer service).
