When you run the pump, slides, lights, and fans at once, your battery can fall behind. Pick your charge mode, watch the LCD, and keep steadier 12V power while your battery recharges overnight.
Most stock converters decide when to charge harder and when to back off, so you don't always know what your battery is actually getting. This adjustable converter puts you in control with three selectable modes: fixed voltage, 2-stage, and full 3-stage smart charging. Pick the approach that fits the way you're using your rig, whether you want hands-off charging and maintenance or you want the converter to stay right where you set it.
With 65 amps available, this converter is a good fit when you regularly have several 12V loads going at once, helping your battery recover while you sleep and keeping voltage steadier for the basics. It also supports flooded, AGM, gel, and lithium batteries by letting you manually adjust voltage. So instead of one generic charging pattern on every setup, you can dial in the output your battery calls for, and your setup behaves the way you expect in an RV, a boat, or anywhere you need dependable 12V power.
When your converter keeps jumping between charging modes, your 12V system can feel unpredictable: lights subtly change, fans ramp up and down, and you're left wondering if something is wrong or if it's just the charger doing its thing. Fixed voltage mode solves that by letting you choose one steady output voltage and hold it there, so your gear gets consistent power instead of riding along with boost, normal, and float changes. You get fewer "why did that just change?" moments, you can match a specific voltage your battery prefers, and your voltage stays steadier when multiple loads are running.
The built-in LCD screen shows real-time output voltage, making it easy to confirm that charging is happening at the level you expect. No matter if you're plugged into shore power, running a generator, or testing on the bench, you can watch the voltage climb, settle, and hold where you set it.
The compact, deck-mounted design works for mid-size systems and heavier daily draws. The temperature-controlled fan helps manage heat without adding unnecessary noise. Built-in current limiting, overload, and short-circuit protection support reliable operation whether you're charging overnight or pushing current during short generator runs.

Hi, everyone, Steven here with etrailer. Today we're looking at a PowerMax AC to DC Converter with a built-in 3-2-1 Stage Battery Charger. Folks, this adjustable AC to DC converter will be great for high-demand RV systems. It is compatible with AGM, gel, flooded, and lithium batteries alike. And with the fixed two-stage and three-stage smart charge, it's gonna do everything for you and then some, right So you do have those LED indicators when it's plugged in and hooked up and in use. It'll tell you which one it's doing, whether it's the fixed, two-stage, or three-stage.
And it gives you current limiting, overload, and short circuit protection as well, so. And the temperature-controlled fan is gonna help everything run nice and quiet. And of course, it plugs in to 120-volt or a 110 outlet, rather. And then you've got the mounting bracket base that's already on there from the factory. So some quick dimensions overall, when I counted the front terminals here, the red and black, all the way to the outside edge, I got 9 7/8.
I got 8 1/8 inches wide. That's all the way outside of bracket to outside of bracket. And I got 4 3/16 inches tall at the tallest point. Now, this also gives you a nice monitor voltage on the top here with an LCD screen, giving you real-time maintenance and voltage showcases. So it's gonna show you those in real time, sorry.
And as far as everything else, folks, if you have any other questions, reach out to us here at etrailer. We're here to assist you in any way we can. I'm Steven, thanks for watching, and have a great day.
