PulseTech SolarPulse SP-12 Solar Battery Charger Maintainer, 12 Watt, Blue

I love these. They work amazing. I now have 4 of these for my dump trailers and never had another dead battery issue. I

This keeps my battery topped off on my Travel Trailer during storage.. Works great.. the other review said it was bent,, I think its made that way. Mine is a little concave, but very strong.. I just zip tie it to the trailer during storage, and take it off when i use it..you just unplug it.. the little red light is kinda hard to see. but it works fine in about 6 hours of sunlight.

A little pricey but worth the money . Have bought cheap ones and this one works 10x better

voltage regulator stopped working after 60 days and overcharged battery ruining it.

We have used several different solar chargers to keep tractors and dump trailers charged up year round. Cheaper ones will break and show fully charged, even when the battery is completely flat.Spend the money. Get the good one.

Can't speak for longevity but the panel and wiring looks to be more durable than the last panel I had. I have it mounted to my dump trailer and I expect that it will work great. Only reason for 4 stars is because shipping left the package, not in a ups box, just original packaging out in the rain and the box was trashed when I found it. Did not appear to be missing any parts but they can do better.

did the job as should

The ease and quality of this battery tender is awesome! Just enough charging to keep my marine battery on my tri toon topped off! Battery level keeps a constant 12 volts! Definitely would recommend!
