Product description
The NOCO GENPRO10X3 is a fully-sealed, waterproof onboard battery charger rated at 30 amps total—10 amps per bank—designed to independently charge and maintain up to three 12-volt batteries. Optimized for lead-acid and lithium-ion batteries, including flooded, AGM, gel, and LiFePO₄ chemistries, it’s 27% smaller and 19% more powerful than the previous-generation GEN3, delivering best-in-class performance in a compact, rugged housing. Each of the three banks operates independently, allowing you to charge multiple battery types or states simultaneously, with selectable charging modes including 12V, AGM, Lithium, and Repair Mode. An integrated thermal sensor constantly monitors ambient temperature and adjusts the charging profile to prevent overcharging in heat or undercharging in cold—ensuring maximum battery life and performance. For batteries discharged below 1 volt, Force Mode enables manual charging down to zero volts, giving you the ability to recover deeply neglected batteries that traditional chargers cannot detect. Engineered for harsh marine and outdoor environments, the GENPRO10X3 features an IP68 waterproof rating and has undergone extensive life cycle testing under submerged conditions. A redesigned mounting system enables quick, secure installation in any orientation—even upside down—and includes an anti-vibration backing to reduce shock and noise. The GENPRO10X3 comes with 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. It is backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410 for ignition protection and marine compliance.

- Reviewed in Canada on April 18, 2024Verified PurchaseThis 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.
- Reviewed in Canada on March 14, 2025Verified Purchaseworking well in my boat
- Reviewed in Canada on September 19, 2024Verified PurchaseUsed it on board my boat for easy charging after boat was put away. Seems to work fine. Advised by battery maker not to leave charging indefinitely but for specific time durations. Very satisfied
- Reviewed in Canada on March 6, 2024Verified PurchaseIt'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.

5.0 out of 5 stars Great product great company!
Verified PurchaseOk a little over 2 years of owning this product it charges batteries up like it's supposed to and has plenty of extra wire to allow for some nice clean routing! It worked like a charm until I forgot to put the plug in my boat and it submerged for a few minutes after that the charger didn't work properly. I had a few emails back and forth wit their warranty dept. They issued me an rma number and 2 weeks later, between me shipping to them and them looking over my old unit. I got a new one in the mail. This company has helpful employees quality products and it appears they stand behind it!! With all that said there isn't enough stars to give them on this review!! They are awesome!

5.0 out of 5 stars Built like a tank!
Verified PurchaseI 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.
Update: I've had the charger connected and working on my boat in the local marina. It does it's job wonderfully. Keeps my house and starter batteries topped off and ready for use. I have no regrets with purchasing this battery charger and would recommend it to anyone looking for a quality product to maintain their boat and/or RV batteries.
