About this item

  • Meet the GENPRO10X3 - Similar to our GEN3, only better. It's 27% smaller and delivers 33% more power. It's one of the best performing onboard marine battery chargers we have ever made.
  • Multiple banks - A three-bank onboard battery charger rated a 30-amps - 10-amps per bank - for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries.
  • Charging modes - Independently charge and control each battery bank with selectable charging modes - including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode - for all types of lead-acid and lithium-ion batteries.
  • Enjoy precision charging - An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
  • Charge dead batteries - Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts.
  • Redefined mounting - A simplified mounting system allows for quick and easy installations in any direction - even up-side-down - with an integrated anti-vibration backing to isolate shock, vibration, and noise.
  • Designed for water - A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater.
  • What's in the box - GENPRO10X3 30-amp 3-bank waterproof onboard marine battery chargers (120-240VAC) with a 72-Inch DC cables with 3/8-inch eyelets and a 72-inch Type-B AC cable, (2) self-tapping mounting screws, user guide, and 3-year warranty.

    Customers say

    Customers like the quality, performance, ease of installation, and battery charging of the battery charger. For example, they mention it's the best marine charger, works flawlessly, and is easy to set up. That said, they like the value. Opinions are mixed on weight and fit.

    AI-generated from the text of customer reviews

    84 customers mention61 positive23 negative

    Customers like the quality of the battery charger. They say it's an awesome battery charger, it charges very fast, and is the best marine charger there is. The 10 amp per bank charges batteries quickly, and it works great. It extends the life of your batteries exponentially, and charges all three at the same time.

    "...It can be plugged in "indefinitely" and causes no harm to the unit or batteries. It seems a little pricey but you get what you pay for." Read more

    "This is an awesome battery charger. Easy to set up. It’s water proof so I mounted in the rear of the boat to save room under the center console...." Read more

    "...The first one I purchased had a bad circuit that did not charge one of the three after a year...." Read more

    "It’s a nice charger for sure. But Amazon had to replace the first one after 3 uses when the middle LEDS went out but did continue to work...." Read more

    I use them, and install them on large boats. I would formally recommend a ProMariner, but this can charge from zero volts.

    I had to replace my onboard charger on my bass boat. I have a 24V trolling motor system (2 batt) and a cranking battery. This was a simple install and worked perfectly when I plugged it up. I've used NOCO products in he past and always feel safe and well taken care of with their products. The two mounting "slots" helped out in mounting this unit vs two mounting "holes". I love the fact that you can plug it in and just forget about it. It can be plugged in "indefinitely" and causes no harm to the unit or batteries. It seems a little pricey but you get what you pay for.

    I purchased this multi-battery charger for use on my live aboard sailboat. I have a lead acid dual purpose batter for starting her diesel auxiliary and a dual LiFePo4 house battery bank. This charger will replace the old charger which wasn't suitable for the LiFePo4 batteries.
    1) it is one solidly built charger! I feel confident it will be up to the task of keeping my electrical storage banks charged.
    2) can charge three batteries (lead acid, AGM, and lithium) at the same time.
    3) the instructions are easy to follow.

    This is certainly not a detractor but I do wish there were a way to connect the charger to my boat's AC power panel without voiding the warranty by cutting the three prong plug off of the power cord. I could, alternatively, wire a wall type plug from the power panel to plug the charger in but I would much prefer to hard wire it to one of the AC circuit breakers. I could also plug it into a DC to AC inverter. I'll have to ponder this a bit.

    But all in all I am, so far, happy and satisfied with this purchase and that it will meet my needs on the boat. Once I have it installed I will update my review with performance results.

    It’s a nice charger for sure. But Amazon had to replace the first one after 3 uses when the middle LEDS went out but did continue to work. 2nd one went out in year two, middle bank out. Had to deal with noco, very slow response and I had to pay to ship it to them! So now I’m on third charger, hope it holds up

    It does exactly what they say it does and it's easy to use and quick to install. I have this model on my 48 foot sportfish to charge three banks of AGM batteries. My house bank is soon to go lithium and I can do that too with this charger. I have another smaller model on my open fisherman. It works perfectly as well. highly recommended.

    This is the third NOCO charger I have bought. I use them all the time for deep cycle marine batteries and they charge fast and extend the life of my batteries.

    They aren't the cheapest charger out there, but in my mind they are well worth it. Even if it gives you and extra year or two on your battery it will pay for itself in a few years.

    It's easy to use and had nice long cords that make application and use really good in hard to reach places like a boat.

    Overall excellent quality and smart technology built in to these. I cannot recommend them more for value and quality.

    It's pretty pricey but I have had good success with other noco chargers, so I have high hopes for this one. I'm sure i will forget about the extra $ after having for a while and it's still working and keeping my batteries going.
