After a long day on the water, you plug in and hope both batteries recover, but one never fully catches up. This 2-bank, 12-amp charger shifts power where it's needed most, so both batteries charge evenly and are ready by morning.
One of the biggest headaches in a multi-battery setup is ending the day with one weak battery dragging down the whole system while the other doesn't need the same charge. This charger fixes that with a 12-amp, 2-bank layout and Distributed-On-Demand technology that automatically transfers unused charging amps to the battery that needs it most. Instead of sending fixed output to every bank regardless of condition, it shifts charging where the demand is. You end up with a more balanced charge across your trolling motor and engine start batteries, so the system is ready without leaving one battery behind.
Charging gets frustrating when you don't know if the batteries are charging, conditioning, or just sitting there. This unit runs a fully automatic 5-stage digital sequence with Analyze, Charge, Condition, Auto Maintain (Energy Saver), and monthly Storage Recondition, then keeps monitoring the batteries long-term. The expanded LED display adds a fuel gauge style charge completion monitor, a four color multi-stage mode LED bar, and individual battery status indicators that show Full in green or Fault in red for each bank. You can glance at it and see what each battery is doing instead of tracing wires or wondering if the charger is still working. The 100-240 VAC input with universal power cord also makes it usable across different shore power systems without needing a separate charger.
Wrong charging profiles are a fast way to create charging problems or shorten battery life, especially when battery chemistry changes across boats and upgrades. This charger gives you selectable charging profiles for Flooded, AGM, Gel, and approved LiFePO4 batteries, so you're not stuck with one generic program. It also supports 12/24 Volts, which matters in setups built around different battery arrangements. When the profile matches the batteries on board, charging behavior stays predictable and you spend less time chasing weak performance that comes from a mismatch instead of the batteries themselves.
Onboard chargers live in rough places, and heat, spray, vibration, or a wiring mistake can turn into a failure at the worst time. This one uses a heavy duty tri-surface extruded heat sink design for optimal cooling and true rated constant current charging, plus 100 percent waterproof IP67 construction for harsh marine environments. Built-in protection covers dual inline waterproof fuses, reverse polarity, over-temperature, over-current, over-voltage, and ignition protection, and the System Check OK indicator confirms proper installation and battery readiness. Once it's mounted and wired correctly, you've got a charger built to stay on the job in the same conditions your battery system already has to live through.

Hi, everyone. Steve here with etrailer. Today we're taking a look together at the ProMariner ProSportHD 12 battery global charge. So if you've ever opened your battery compartment and dealt with tangled charger cables, dead batteries, or even just a hassle of charging batteries one at a time, because you have so many different options, this is the kind of upgrade you're gonna need to make your boat ownership a lot less stressful, and just your life a lot easier. So this is the ProSport Heavy Duty 12 global. It's a 12-amp two bank onboard marine charger that's going to automatically charge and maintain two separate batteries no matter what style they are that fits this unit.
And it's gonna be perfect for smaller fishing boats and dual battery setups. And because once you get it mounted the first time, it's gonna then be permanently mounted on board, you don't have to worry about dragging around portable chargers, extra wires, constantly reconnecting cables. Just plugging the boat after your trip. The chargers are gonna do everything for you. And what makes this version stand out from even some of their other ones is, it uses this global voltage compatibility.
So you can buy different adapters depending on where you are around the world and it'll work and automatically detect the different changes in voltage and it'll work across a wider range of input voltages without needing a lot of extra parts and equipment. And again, it's been built specifically for marine applications. It's sealed, it's waterproof. it's vibration resistant design is gonna help handle the moisture, the heat, the rough water conditions that are out there. It does feature a 12 inch charging output, two bank charging system, multi-stage charging automatically.
And like I mentioned before, it's compact and small. So we're looking at about 7.9 inches across by 11.3 inches long and about 2.9, almost three inches tall, not quite 3 inches. So again, small compact, one and done. Get yours today. This is the ProMariner ProSportHD.
I'm Steven with etrailer. Thanks for watching and have a great day.
