Product 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.
