The GENPRO10X3 from NOCO is a fully-sealed, waterproof onboard battery charger rated at 30 amps total—10 amps per bank—designed to maintain and charge up to three 12-volt batteries independently.
Optimized for lithium-ion and lead-acid 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 rugged, compact 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 undercharging in cold or overcharging in heat—maximizing 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, certified to UL1236, ISO 8846, and 33 CFR 183.410 for ignition protection and marine compliance, and engineered in the USA.
