Keep your 12V system charged and ready without adding another maintenance task. This 20-amp, 3-bank onboard marine battery charger delivers controlled multi-stage charging and long-term battery care, so you're not troubleshooting before launch.
When one battery bank is drawn down more than the others, fixed-output chargers can leave the system uneven and harder to trust. Distributed-On-Demand technology automatically senses demand and directs available charging amps to any one bank or across multiple banks as needed. On a 3-bank system, charging stays focused where it's needed, so you're not second-guessing which battery is going to lag behind.
Batteries that sit without proper maintenance lose capacity, and that usually shows up when you're expecting everything to be ready. This unit cycles through Charge, Condition, Auto Maintain, and Recondition stages to keep batteries at proper levels between trips. After 21 days in maintain mode, it automatically de-sulfates to restore lost capacity, so you can leave it connected and come back to batteries that are ready to work.
Multi-bank systems are only as reliable as the charging profile behind them. This charger includes 12 selectable profiles and supports Flooded, AGM, GEL, Lithium (LiFePO4), and Calcium batteries with custom settings available. Matching the correct profile keeps charging behavior consistent across the system, so you're not dealing with uneven performance between banks.
Not every dock or marina delivers consistent power. This unit includes selectable power levels that let you reduce AC input to 100%, 75%, 50%, or 25%. That keeps charging stable in low-power situations without overloading circuits, so you're not managing breakers just to keep batteries charged.
Charging issues are easier to catch when you can see what's happening in real time. The digital information center displays system voltage and amperage, while built-in fault indicators alert you to wiring issues or adverse conditions. You can quickly confirm output and spot problems before they turn into dead batteries.
Charging shouldn't depend on having perfect power conditions. This unit uses 100-240 VAC input at 50-60 Hz with power factor correction and auto-ranging input, so it works across a wide range of shore power setups. That keeps charging simple whether you're at home, at the dock, or traveling between locations.

Hi, everyone. Steve here with etrailer. Let's take a look at the ProMariner ProNautic 1220P battery charger. So if you're running multiple batteries on your boat, keeping everything charged and maintained can become a hassle fast, as we all know. So if you're juggling portable charters, multiple different plugins 'cause you've got multiple styles and types of batteries, it's just got a lot of a hassle. So what's nice about this is that it can do everything and simplify that process.
Multi-bank systems are only reliable as the charging profile behind them, and that's what this is gonna do. It's got 12 selectable profiles. It supports Flooded, AGM, GEL, Lithium, LiFePO4, and Calcium batteries with custom settings available. So it's gonna match the current profile. It's gonna keep charging consistent across the system so you're not dealing with uneven performance between the banks.
And it's a 12-volt, 20-amp, three-bank charger. So it's gonna do that automatically. And this will be great for trolling motor systems, cranking batteries, house or accessory batteries. And once you get this installed, it's a permanent mount. Charging's simple, after you're down the water, just plug in the boat and the charger automatically matches all those batteries right for you.
And to me, one of the standout features is its smart digital charging system. As I already mentioned, it's gonna automatically pick the battery condition, the demand, what type of battery, and do everything automatically. And as we know, it's built for marine lifestyle. So it's water-resistant, vibration-resistant. Waves, moisture, heat, rough water, it's made and built to handle all of that.
And of course, you got your connections for the batteries down here. Simply take off this little front cover, and then you can connect your battery cables, get a communication cable included as well. And you can purchase separately another screen that you can put somewhere else if you need to look at anything, you know, a lot closer to where you're at and don't have to go down there inside of the bank itself to open it up. But you do get everything on the face panel here that's gonna give you readouts in real time. Pretty small, 10 1/4 inches tall, 8 1/2 wide, 3 1/2 inches thick or deep depending on how you're looking at it. So again, the compact footprint's gonna save space in your crowded battery compartment while still delivering solid charging performance for years and years to come. Folks, this is the ProMariner ProNautic 1220P. I'm Steven. Thanks for watching.
