Keep your battery ready between trips without overcharging or constant checks. This 4-amp onboard charger uses multi-stage charging and auto-maintain to protect battery life, while a power inlet design keeps setup simple and flexible.
A battery that sits too long can lose charge or wear down faster than expected. This charger uses a fully automatic multi-stage charging process with conditioning and Auto Maintain to keep your battery at the right level between trips. It helps extend battery life while making sure it's ready when you need it.
Running power to your charger shouldn't require extra wiring. The integrated AC inlet lets you plug in using a standard extension cord, giving you flexibility to connect shore power at home or at the dock without modifying your setup.
It's easy to forget where your battery stands after sitting. The push-to-test LED fuel gauge shows remaining battery power at a glance, so you can check status quickly without hooking up tools or opening compartments. :contentReference[oaicite:1]index=1
Charging issues don't always show up until it's too late. Built-in fault detection alerts you to reverse polarity, poor connections, or batteries that are too low to charge. That gives you a chance to fix issues before they turn into a dead battery at the wrong time.
Boat compartments and outdoor installs expose chargers to moisture and vibration. This unit uses a gasketed, weatherproof housing with durable, jacketed cables to hold up in harsh environments and keep connections protected over time.

Hi everyone, Steve here with etrailer. Today we're taking a look at the ProMariner ProTechOne 4 Amp Charger and Maintainer with a Power Inlet. Now folks, this is gonna keep those boats, RVs, and recreational vehicles stored for a long period and not have to worry about dead batteries and those kind of things. Again, it's gonna provide four amps of automatic charging power, making it ideal for long-term maintenance in smaller battery systems that don't need a lot of high-output charging. And as you can see, you've got the one cord coming from here with the battery terminal connections and the plug on the back. And then up here on the top, you've got some light indicators, a little test button, and then a battery monitor here on the screen.
So it's gonna give you real time of what it's doing, whether it's charging, maintenance, power's on, and then you get that test button again and see what the battery life is looking like and how charged it is. So again, this is gonna be great for boats and closed trailers, where all those things need, you know, long-term storage and this is gonna make charging easier. It's on a small, compact unit (charger thuds) and it has been designed for marine applications. So it is designed to be on boats near the water, on the water, and take those waves, the moisture, and temperature changes and those kind of things that you'll see in compartments and stuff like that. And then once it's installed, it's gonna become one of those systems you barely think about, because your batteries are gonna be charged every time, they're gonna be maintained, and ready to go.
I'm Steven, thanks for watching.
