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

Good converter

Replaced the same the same converter that was a little older. Works fine so far, but way louder than the older unit that we never even hear unless we were right next to it. Pretty disappointed about the noise level.

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.

Out of the box, set at 14.77v, yiur results may vary, but mine was ready to go.

Amazing product

Quick and easy to use charger, use it for multi cars in a body shop. works great.

Replaced my blown converter in my camper works amazingly

Just got yesterday a week ahead of when they said and I hook up today works looks great

Great

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.
