Review on ⚡ 55 Amp PowerMax RV PM3-55 12V DC Power Supply Converter Charger - 110V to 12V by Kyle Hoes

Revainrating 5 out of 5

Works great for me.

I am very happy with this unit. I bought the 55A version to replace the Magnetek 6345 (45A) converter in my 1996 Fleetwood. I pulled out the charger/converter version and added an outlet under the fridge on the side of the original. I could have cut the cord, but that was easier for me. I plan to use this to charge a few 105 amp hour AMGs and I think it will be fine for that. With my clamp meter I got over 20 amps out of the battery which I now have which is what I was expecting. When this happens I get 13.7 volts in the camper, which is what I was expecting. I haven't tried turning on other items on the bus and using a clamp meter to see how much it's outputting, but I don't see anything that would indicate anything less than the nominal limits. I will update this if anything changes as I am currently on a 2 month trip. The only thing I will say is because it wasn't easy to find on the internet. If you're replacing a Magnetek like I did, you'll need to connect the blue wire that connects to the 12v fuse panel to the 12v connector that the red wire connects to.

Pros
  • 13.6V DC range
Cons
  • Big and chunky
