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

Works better that my original factory 55 Amp Converter, and it arrived promptly.

Works well

I use this professionally as an automotive technician. It allows me to supply a clean DC power supply to the vehicle while I perform sensitive tasks like control unit programming. Modern day system control units sometimes allow a programming operation only one time to a module. If communication is corrupted at any point, youve essentially bricked it. What I love best about this product is the battery charging feature. It was able to bring back old dead batteries that other chargers could not. It has very literally saved me money! Also, the 55 amp (for this model) crank assist feature is STRONG. Remember youll need to make up some leads for yourself if you intend to use it like I am. I cut up an old set of jumper cables.

Bought this for a 2010 Keystone Hideout 23 ft camper. I just cut the cord and wired it directly like the original converter. Had to fold the rear tabs under due to depth limitations. 30 minute install and now I dont have to waste vehicle gas to charge battery and my replacement LED bulbs are super bright.

The length and width were ok but depth of my distribution panel was short. I was able to cut off one side of mounting feet and now is ok. The 3 stage rate is exactly as specified. The fan noise is noticeable but not excessive. Very satisfied with operation at this point.

Easy to install. Replaced old converter because no longer charged coach batteries. Has adjustable charging capability. Great price.

So easy to install. Works like a dream. Replaced the piece of junk that my rv came with, and could not be happier. No more dim lights

Installed this Powermax just on 2 years ago and it has run, and still runs great!! Fans kick in every now and then but the best part is my house batteries are charging so much better now. I went through a couple of house batteries when I realized it was the power converter charger (Progressive Dynamics) that was pretty much cooking the batteries. Not so anymore with the 3 stage charging from the Powermax. The unit was a little larger than the original but with a Dremel tool and a few well-placed cuts in the main Parallax/Magnetek power center housing, I was able to get it installed neatly. Installed in a 2007 Winnebago Access 29T.

As advertise easy to install packaging was good quickly got here and it’s been running ever since two months no issues

Installed in my toy hualer works great. Definitely a upgrade from the old one.
