Powermax 110 Volt to 12 Volt DC Power Supply Converter Charger for Rv Pm3-55 (55 Amp)

Very easy to install. The item has worked perfectly as described. The only downside is the fan. It is very noisy. We have our power supply underneath in our storage compartment, but we are able to hear the fan in the kitchen. Wished I would of known that before the purchase. It gets annoying especially when your trying to sleep.

Easy install and no noise at all, works great in our 5th wheel

Couldnt just plug it in to an older system so installation can be difficult. I am using in a truck camper. Now that it is installed I am very pleased with it so far.

Does what they say. Once you get it fine tuned in. I prefer using the middle setting on charging an battery an running auxiliaries. Ran on 1 an 3 the fan kicks on an then turns off. I’m not sure if it’s supposed to do so. But works great an doesn’t produce a lot of heat it stays fairly cool. I’ve put atleast 100+hours on it in the past month an it works properly! Good buy for the money

Super cool!!! Easy to hook up, great quality and charging my Lance cab over battery like a champ at 14.6 Volts. The Parallax power unit I had running my Rig burned out for the forth time since 1997 mind you, but I’m not spending the time or money for one of those again. So I bought this unit and relocated it to under my sink for better air flow and easy to replace if this unit ever goes out. Have size 8 AGW wire on hand because that what this unit requires and what size wire that should be used.

Works real good

Works well

I work for Mercedes Benz and their equivalent cost 1,000$ from midtronics. This does the same thing for under 200$!!!

Was very easy to install and works great, have had on my rv for a couple of months and still working great.

Researched the options, and this fit the bill for the OEM charger in my trailer. Works great since then, been running for nearly a year, keeping the house battery topped. I did have to modify the the housing this fits into on the trailer since its a little deeper than the original. Otherwise, hookup with new wire was easy.
