If your battery drains between short trips, stop guessing if it's actually charging. Pick fixed, 2-stage, or 3-stage mode, watch real-time voltage on the LCD, and keep your 12V basics steady while the battery catches up.
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.
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.
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 12V 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 troubleshooting is a whole lot clearer because the charger isn't shifting the conditions while you're trying to find the actual issue.
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 fits easily in cabinets or utility spaces, and 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 our PowerMax AC to DC converter with a built-in three, two, one stage battery charger. Now folks, this is compatible with AGM, gel, flooded and lithium batteries. The three built-in charge options are fixed, two stage and three stage. And when this is powered up and in use, those indicator lights here will light up depending on what stage you're in. And you also have an LCD monitor here on the top.
That LCD screen will let you monitor voltage in real time. You got all your connection ports here on the side with the nice fan. That fan is a temperature temperature control fan, so it's gonna run a lot quieter than most fans out there on the markets. And what I like about this is it's a flexible voltage. You can adjust it for specialty applications and such.
So the technology on these inversions keeps getting better and better every year, in my opinion. Again, this output current is rated at 35 amps, which it also says here on the top, we do carry these in multiple amp options, so if this isn't big enough for you or whatnot, reach out if you can't find the right one you need and we can assist you and answer any questions as well. Now, counting these terminal leads all the way to the back here, I got nine and 7/8 inches long overall, and then counting the mounting bracket here that's built in on the base, that is the widest part technically of the unit. I got eight and 1/8 inches outside to outside on those mounting brackets and four and 3/16 inches tall overall. Folks, that's gonna wrap up our quick look together.
I'm Steven, thanks for watching and have a great day.
