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

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

Directions left a little to be desired but works great in my RV

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

Got this last May for my camper. Worked great until last week when the voltage regulator went out. I called the company and they shipped me a new one in 3 days.

Before purchasing I read reviews, and some said this unit would not output the rated current. I have seen this 55amp unit output 45amps when my two group 31 batteries were at 12.5V with an additional 12V load of 16 amps. Also it switches between charging cycles as you would expect. But FYI, I have a Honda EU1000i generator and it cannot start this charger if the battery voltage is below 13.4V. So I needed to use a 10 amp charger, bring the batteries up to 13.4, and then switch over to this charger. I called the manufacture to ask if there was any way to limit the maximum current. And they answered the phone! There is no way to adjust it. You can adjust the voltage levels but this would not be enough or the correct way to fix this. They told me for my Honda eu1000i I would need to go to the 35 amp model. The fan is noisy and only runs at one high speed.

So far so good, I use it to charge the two house batteries and all the other dc stuff in the bus,If you get an over load like I did due to my wiring error it shuts unit down an says OL ,then you just power it down unplug and restart once your wiring is good again ,It puts out 3 separate charge amounts allowing constant power to what needs juice, the 14.9 volts for house batteries ,Im pretty happy with the unit ,the fan tends to run a fair bit but its not noisy and hasnt changed since Ive had it and its ran for months non stop.

Easy to install. Solved my dimming issues with the 12 volt system and undercharging of the battery. Was a replacement to the OEM WFCO unit that didn’t last a full year of usage.

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

Super easy to install.

Works like a Champ on our RV
