Review on ⚡ 55 Amp PowerMax RV PM3-55 12V DC Power Supply Converter Charger - 110V to 12V by Demetrius Patsion

The PowerMax PM3-55 worked fine on the workbench and charged my new AGM batteries. I like that the tension is adjustable. There is a tiny switch that allows you to set the fixed voltage (set with a small trimmer next to the switch). Important note: the setting affects the voltage in each switch position (including the "normal" setting, which affects the voltages during the 3 charging phases: bulk, absorption and floating), but in any case the adjustability is a plus! the unit didn't quite fit (an exact replacement for the WF-8955 Converter/Charger) in my son's RV (though very close and could probably make it work with a little modification). Since this was intended as an "upgrade" (and the original still worked) we decided not to touch it and left the original in place. In any case, I'm sure I can use it as a good charger for my car batteries if needed.
