Powermax PM3-55LK 55 Amp 12 Volt Power Supply (Replacement for WFCO WF-9855) Battery Charger with 3 Stage Smart Charging Mode, Built-in Cooling Fan and LED Indicator Light, Lithium Compatible

A lot of reviews mention how loud it is. Well, it is certainly louder than the original one. However, to replace the original one it would be at least double the price. We call that a push. Ease of install will vary depending on your rig. For mine I needed to get another piece of ground wire as the lug is in a different location the the original one. That said, if you think you will ever need to adjust the voltage be mindful on where those switches are when you install it. Otherwise, it works well.

I use this unit as a solar charger for a backup system. It installs easily and it has a very high build quality. Since it is being used for a back up it will probably not get a lot of use, However I expected it to behave flawlessly when I need it to.

My new batteties would do a nose dive with the old converter! This was properly set for voltage and charge rate and it does the job. very easy install. Excellent get one>

Im pleased with this product good power and decent price. Dont know the lifespan but hopefully years to come.

This unit works fine but is very noisy. Too late to send back, but I would iff I could. It will keep you awake at night when it turns on.

This converter replaced the blown one in our camper perfectly. Only thing necessary to use it was to add an outlet to plug it in which was way less expensive than buying the original replacement part. And in doing so we didnt alter it so as to void the warranty. We have been using it for weeks now with no problem at all...very happy with this unit. I forgot to take a photo after my husband installed it or Id share his handiwork.

Good converter

Great

Two RV -Bought TWO. One mounted in the living room. The fan is so loud I had to unplug it. The second was mounted in a 5th wheel Basement and it could still be heard in the living quarters. I WISH IT WHERE NOT SO for everything else including the price was great.

Fast shipping, easy to install
