> 3 dayThe length and width were ok but depth of my distribution panel was short. I was able to cut off one side of mounting feet and now is ok. The 3 stage rate is exactly as specified. The fan noise is noticeable but not excessive. Very satisfied with operation at this point.

> 3 dayI use this professionally as an automotive technician. It allows me to supply a clean DC power supply to the vehicle while I perform sensitive tasks like control unit programming. Modern day system control units sometimes allow a programming operation only one time to a module. If communication is corrupted at any point, youve essentially bricked it. What I love best about this product is the battery charging feature. It was able to bring back old dead batteries that other chargers could not. It has very literally saved me money! Also, the 55 amp (for this model) crank assist feature is STRONG. Remember youll need to make up some leads for yourself if you intend to use it like I am. I cut up an old set of jumper cables.

> 3 dayThe converter arrived on time and worked perfect right out of the box! My motorhome batteries were low so it ramped right up to 14.6 volts, stayed there for about 2 hours, then dropped to 13.8 volts for about 4 hours then went to 13.2 volts and has maintained there ever since. The next day I turned on the furnace all of the lights and both tvs and it held steady at 13.3 volts. It has only been a few days, but at this point I couldnt be happier with this Power Max Converter! Here is the link to a pdf that shows how to install it, that was easy to follow and worked perfectly. Ive had it now for a couple of months and it is still performing great! [...]

> 3 dayI couldnt be any happier with this purchase! Great quality American made product at a reasonable price. Does exactly what its supposed to do right out of the box. My 20 year old 45 amp converter went belly up, so I replaced it with this 55 amp unit. Unit was on my doorstep within 48 hours. Took about 30 minutes to install including time to drill a couple of new holes to accommodate the larger unit. House batteries were fully charged within 12 hours and system voltage has been floating at 13.1 ever since.

Greater than one weekEasy to install, the unit is very quiet, even with the fan running. Power is very very clean, my new 12v fridge runs great on it without the LED lights flickering like the other converter did.

> 3 dayEasy 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.

> 3 daySuper cool!!! Easy to hook up, great quality and charging my Lance cab over battery like a champ at 14.6 Volts. The Parallax power unit I had running my Rig burned out for the forth time since 1997 mind you, but I’m not spending the time or money for one of those again. So I bought this unit and relocated it to under my sink for better air flow and easy to replace if this unit ever goes out. Have size 8 AGW wire on hand because that what this unit requires and what size wire that should be used.
