    Easy to install and simply works great. Can have all 12v lights in my travel trailer on and they never run down when the unit is on - which was not the case with the original unit i had. This Powermax is really a great repalcement unit

    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 far, soo good. Its been running 24/7 for a month now with no glitches. The original unit in my RV was not keeping up with the demand of the two furnace motors and its been very cold. The reliability of the unit over the long haul is yet to be verified, hence the 4 stars.

    Researched the options, and this fit the bill for the OEM charger in my trailer. Works great since then, been running for nearly a year, keeping the house battery topped. I did have to modify the the housing this fits into on the trailer since its a little deeper than the original. Otherwise, hookup with new wire was easy.

    Installed the converter in June of 2021, stopped working in September 2022. Luckily I was on a local camping trip where I could return home and pick up a battery charger and return to the campground and charge my batteries up enough to get the landing gear retracted. When I got home I did some troubleshooting and tried to find warranty information on Amazon and couldn’t find any so the top of the converter came off and I discovered a blown fuse on the circuit board that was soldered in. Bypassing the fuse with some alligator clips resulted in a blown capacitor. So it buying a new converter for me. Not happy with this one only lasting 15 months. Lucky it happened to me on a local trip and not my wife on one of her boon docking horse camp outs. When it worked it was great but reliability is very poor.

    Wed been having issues with our second WCF 9880. The second WCF had been in for 3 years and in the last year had been spotty in its use. Had to turn off the power several times and reset the WCF. Read any number of great reviews about the Powermax. Bought one, changed it out for the WCF 9880. Wow - right out the box it just works! Started off at 14.4 volts to take up the slack for the WCF, after about 2 hours dropped back to 13.6. Looking for the 13.2. Some other reviewers stated it was noisy - not for us. Fairly quiet. Fingers crossed it lasts for more than 2 years.

    My Atwood had brackets factory riveted to secure in place. I transferred those to the Powermax. Make sure your not drilling into to something critical inside if you do this. Also my Atwood was wired into a junction box, the Powermax comes with a standard 120v plug. I added a quality 20amp outlet and was in business. I also changed to 2 6v golf cart batteries wired in series for more capacity. I have been cooking batteries for a few years now. Those days are over. So happy I put this in.
