Fifth Wheel & Travel Trailer (Class B&C RV) Hi Power Super Magnetic for 1-2 x12V Lead Acid Batteries Dims 17.5" L x 10.3" W x 1/4" Thick. 10' Cable.

I have used the solar panel now for a few storage trips. Each time I have come to a 4.4V battery. Not good. After doing some troubleshooting, I found the 2 prong plug positive and negative are opposite then the plug on the 5th wheel. In other-words the negative lined up with my positive in the 5th wheel. I had to switch the battery hookup terminals to keep the positive inline the way to the battery. Not sure who's fault, but plug and play may work, but you need to make sure the wires are correct on the camper.

This product guys is a God sent, so let me tell you about it, my wife and I was going to use ours fiver to go camping and we got to the storage hoping to get in and go well we was wrong my batteries was dead.So to make a long story short I had to charge my batteries just so I will be able to bring my fiver down so we could hook up, it took me and my wife about 1 1/2 trying to charge the batteries and needless to say we was not happy.So now since I install this batteries solar charger I can go out to my five no matter how long my fiver sit in storage and bring my fiver down so I can hook up and bring my slide in and out. So a big thanks to the seller and if you are one the fence get it and get it now and yes I know it cost a little more than I wanted to spent but it's worth it.

Love the size! I have a travel trailer instead of a fifth wheel so I stuck this to a metal plate with a handle so that I can move it to where the sun is. The line is too short for my needs so I don't get all day sun. If it wasn't for that I believe this would be an amazing trickle charger and would keep up with my limited power usage when I boon dock. Since I cannot confirm this I gave it 4 stars - but I do recommend it so far.I really need to find an extension line to use when camping. Haven't really tried it for keeping the batteries topped in storage yet so cannot speak to that.

I purchased this panel a couple years ago to keep the batteries topped off in my fifth wheel. It has done a great job of that, and the magnets are strong enough that I leave it attached to my kingpin at all times, even while driving down the freeway. The customer service is also outstanding. I’ve called with questions and Rich walked answered them and helped promptly and me out a ton.

Made in the USA, is fused, includes three adapter cables and is self-regulating. I use it to keep qty=2 12v RV batteries charged while in storage. Mounted to my 5th wheel king pin with strong magnets. I called the support number and spoke with Rich on a Saturday afternoon. Great customer service and that is so rare these days! Definitely recommend this product. Check out their other products as well. I want to add the folding 100 watt travel panel soon.

works really well for me! i wired mine to the constant power in my 7 way junction box located on my pin box (vs running wires back to the actually battery) was a super clean install and saves my batteries. i used to have to bring the trailer home to charge every 2-3 months. fits really well on my pin box and looks really pro.

I stuck it on top of my propane covers. It produced about 18 volts when tested. I hooked it up to my two deep cell batteries but it would not keep up so now its hooked up to one.

Easy to use , batteries for 5th wheel trailer.
