> 3 dayI replaced my RV converter with this, i expected it to be a temporary measure but its held up fine. Ive got 300 watts of solar panels so it doesnt generally have to do a lot of work but im still impressed it has lasted so long.

> 3 dayGot 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.

> 3 dayTroubleshooting 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.

> 3 dayI watched many RV YouTube videos to research for a replacement for the converter for my RV after the factory one quit. I think this converter will maximize may deep cycle battery life because of the 3 stage charge rate.

> 3 dayExtremely well packaged! The PM3-55 arrived in perfect condition. Installation was easy (for lead acid battery there is no need to adjust) Super simple installation, my coach batteries were at 10.1v according to the Solar regulator, fired up the genny and the PM3 was immediately reading 14.64v output on my calibrated multi-meter and 13.1 on the solar regulator (reads @ the battery bank). Ill update as time goes on, my comparison will be against a 1992 vintage supply/charger so I am sure this unit will exceed my expectations.
