Description

The NOCO GENPRO10X2 is a rugged, fully-sealed onboard battery charger rated at 20 amps total—10 amps per bank—designed to charge and maintain two 12-volt batteries independently. Compatible with both 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 GEN2, offering unmatched charging performance in a compact footprint. Each bank functions independently, allowing you to charge different battery types or conditions at the same time with selectable modes: 12V, AGM, Lithium, and Repair Mode. An integrated thermal sensor ensures optimal performance by adjusting the charge based on ambient temperature, preventing overcharging in heat and undercharging in cold weather. Force Mode lets you manually initiate charging on batteries as low as zero volts—ideal for reviving heavily discharged or neglected systems that would otherwise go undetected. With an IP68 rating and brutal life cycle testing under extreme marine conditions, the GENPRO10X2 is built for reliability on the water or in the field. Its reengineered mounting system enables secure installation in any position—even upside down—with an integrated anti-vibration base that reduces shock and noise. The GENPRO10X2 includes 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 to meet demanding marine and ignition safety standards.

  • The best out there
Size: 20A (10A per Bank)
I mounted this charger on my boat to maintain the batteries when not in use. These chargers are beyond great, and will keep your batteries charged or brought back to life when they die. This is the second charger I’ve bought from Noco and highly recommend them for everybody. They are expensive but worth every penny. ... show more

  • Perfect for the boat
Size: 20A (10A per Bank)
I bought two of this for my boat. It is nice to have chargers that work for all battery types I would ever use in my boat. I just upgraded to lithium ion batteries for my trolling motor and repositioned them to the front of the boat for weight distribution. I use the other charger for my cranking battery and another lithium ion battery for graphs etc. nice to just plug them in and know they will be ready for use next time on the water. ... show more

  • Don’t modify the cables or if you do, include the sensor in new cables.
Size: 20A (10A per Bank)
Bought this charger as I had good luck with their smaller trickle chargers. Needed the option to support AGM and LiFe batteries so my old one was not cutting it anymore. Installing in a boat so needed to customize the wiring. Either fight the urge to modify the cables or do it correctly. There is a small sensor in the first plastic node. If disconnected, charger will just flash all its lights and TMK, there is no mention of this error in the manual. Other than that… it seems to be doing it job. ... show more

  • Top of the line charger
Size: 20A (10A per Bank)
This is the last battery charger you will buy. Just purchased a second unit for my numerous motorcycle, car, AGM, GEL Cell and Lithium batteries. This charger does it all. You can't buy a better unit. In over 45 years in working on cars, this is the highest quality battery charger I have found. You know what they say, you get what you pay for. Go for it, you're worth it! ... show more
