Big upgrade for my 2002 RV! Updated by batteries to lithium and my old charger was not capable of charging them. This one is easy to install and overall improved my whole DC system. Had a question and contacted the company, fast response from them with directions

J’ai remplacé le convertisseur d’origine de ma roulotte et il fonctionne à merveille. Je suis très satisfait. J’ai dû modifier la prise 110 volts par contre.

Wired it up in an RV, fired right up and working fine, fan only runs every now and then, unit isn't hot to the touch at all even under load. Checked the voltage and it was doing everything right. It's a hair wider than the replacement unit but nothing a little trimming here and there off the ugly brown electrical box cover won't take care of. Charged up the 2 big batteries I have and idles without the fan charging and running all the dumb crap in the RV, I'm going to leave it on in the heat and see how it does, other than that it seems robust enough to get the job done. Update, I left it running doing it's thing for weeks, sometimes with ac sometimes without. It dealt with the summer heat inside the RV just fine, the inside temperatures sometimes climbing into the 118 range and it just ramped up the fan more often and took care of business. Update 2: still handling the 24 hours a day of being ravaged by the various 12 volt accessories I have running in the RV, I even hook random car batteries to the system to charge them up and it takes care of it, with the minor amount of air circulation the poor unit gets its holding up the the tortures of being in my vicinity. For anyone that has had a unit "blow out" I would suggest they invest in a high quality surge protector for their RV or to plug the one they are using inside the house or shop into a decent surge protector, if not, it's all you when it gets smoked. Update: bought June 2019 and it's now Feb 2020, power supply still runs perfectly and have had no damning issues at all, definitely a very strong and well made unit. If it can survive me and all the dumb things I do it's definitely a must buy. I will update again at one year with the final conclusion. UPDATE: July 2020, unit is still running strong and no signs of wear after two summers of heat and 24 hours a day use, charged a few car batteries with it since then also and it ate it like a pro, definitely a good purchase and if it blew out today I would order another, definitely did it's money's worth of work. Update: mar/2021: still trying to kill it, the bad boy survived covid, a snowpocalypse, a wore out battery, 24 hours a day use continuously since the original purchase and its still going. I still hook batteries up to it to charge them every now and then also and it eats it like a barbarian. It even survived an A/C failure and it chugged along doing its job in 110 degree heat for a day with shoddy ventilation, I am going to buy another for the workbench just because. Last update: 26 oct 2021: I can't kill it.

The PowerMax PM3-55 worked well on the bench and charged my new AGM batteries. I like the fact that the voltage is adjustable. There is a tiny switch that lets you adjust a fixed voltage (set with a small trimpot next to the switch). Important note: The adjustment affects the voltages on either setting of the switch (including the "normal" setting which affects the voltages during the 3 stages of charging; Bulk, Absorption, and Float), but either way the adjustability is a plus !The unit did not quite fit (as an exact replacement for the WF-8955 Converter/Charger) in my son's RV (very close though, and probably could have made it work with slight modification). Since this was intended as an "upgrade" (and the original was still working), we decided to leave well enough alone and leave the original in place.In any case, I'm sure I will be able to make use of it as a nice charger for my car batteries when needed.

Easy to install, however the original unit had two transformers in it, and I had to run a wire across from the positive output of this one to feed that side of the board.

I ordered this converter to replace the giant OEM converter that was sucking our house batteries dry in our 1986 Foretravel Grand Villa "Barn Find" restoration project. The install was straightforward and simple. I have watched the converter for about a week now and it is keeping the batteries very stable and functional. I have attached a picture to show the compartment that will be an Auxiliary electronics bay. Eventually this will mounted on an aluminum slide out tray for servicing or additional wiring. Although the old converter was a 75 Amp converter, I seriously doubt that the old converter would push the 75 amps, so in this instance, I opted for the 55 Amp model. Under full load, the Powermax is more that adequate. Also the fan noise is about 80 decibels less that the original. Its fan is temperature controlled and is not much more than a whisper when on. the old converter sounded like a box fan from the minute it went on shore power and ran constantly.My thought is: If you are looking to replace your old battery burning converter, look no farther. The Powermax converters are dependable, quiet and will do the job you need quite admirably.

Got it the other day and installed into my RV, stupid easy install made easier by instructions. Everything works perfectly and charged my 6v deep cycle batts from dry to full rather quickly. Awesome product at a great price
