The description shows a 4 stage, but it’s only 3. I can’t tell you if it works, or how well, I sent it back without installing.

Called Powermaxx to get a recommendation on replacement unit for Parrellox 7444. They called me back quickly and advised me on what to get. This one went in easy and seems to be working great.

I installed this in a travel trailer, plugged in to a 120 Volt outlet. Used 4' of 6 gauge wire to connect directly to LiFePo4 battery. Although none of these converters output power as they are rated, this PM3-55LK put out 45+Amps. It immediately output almost 700 W until the battery was 98% charged. The voltage increased to 14.6 V As the average decreased to very low. Then continued to power my 12 V appliances without discharging the battery. This device worked perfectly for me.

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.
