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

Easy to install and simply works great. Can have all 12v lights in my travel trailer on and they never run down when the unit is on - which was not the case with the original unit i had. This Powermax is really a great repalcement unit

Works well

This item has to have a constant power voltage coming into it of 110 to 120 to keep your care battery charged

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

Set this up to run my trolling motor. Has two modes. Constant voltage or phased charging. Easy to follow directions, but will need a volt meter to set up correctly.

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

The grill over the fan was bent in against the fan. I pulled it out and it works .

Troubleshooting electrical issues in my new to me used RV revealed no 12 volt power charging the house batteries when plugged in to shore power. Sure enough -- the old converter was shot. Looked online for replacements and found this Powermax converter at a reasonable price and in a form factor that would easily replace the dead converter. The 12 volt connections tighten down easily using a slot screwdriver. The previous converter used hex allen screws, which can be a pain if you have misplaced or lost the proper size wrench. No issues here--everybody has lots of screwdrivers--even neighbors! The two 30 amp safety fuses are easily accessible if you ever need to replace them--a nice touch. The converter is quiet and charges in three steps just like advertised (confirmed by my voltmeter). I bought the 55 amp model as my previous converter was also 55 amps. But, I would not hesitate to go for a higher amp model if I were to do this again.

So far it has done as should. Very pleased!!! We installed it on our boat to keep the battery charged and run the 12v system while in the harbor. Working great. Could not be happier!!!

Easy installation! hammer drill, flutes plug anchors, proper sized screws for anchors, and you’re on your way!
