NOCO Genius GENPRO10X3, 3-Bank, 30A (10A/Bank) Smart Marine Battery Charger, 12V Waterproof Onboard Boat Charger, Battery Maintainer and Desulfator for AGM, Lithium (LiFePO4) and Deep-Cycle Batteries

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.

• MEET THE GENPRO10X3 — 27% smaller and 33% more powerful than the GEN3. It’s our most compact and advanced onboard charger yet - engineered for peak performance in the harshest marine environments.
• MULTIPLE BANKS — A three-bank onboard battery charger rated at 30 amps total - 10 amps per bank. Independently charge 12V batteries in marine, boat, starter, and deep-cycle systems.
• CHARGING MODES — Selectable modes for each bank: 12V, 12V AGM, 12V Lithium, and 12V Repair Mode. Independently charge and maintain all types of lead-acid and lithium-ion batteries with precision.
• ENJOY PRECISION CHARGING — An integrated thermal sensor adjusts charging based on ambient temperature, preventing overcharging in heat and undercharging in cold for optimal battery performance.
• CHARGE DEAD BATTERIES — Charge batteries from as low as 1 volt, or use Force Mode to manually begin charging batteries down to zero volts to recover deeply discharged or neglected batteries.
• REDEFINED MOUNTING — A simplified mounting system allows for fast, secure installation in any orientation - even upside down - with an integrated anti-vibration backing to isolate shock and noise.
• DESIGNED FOR WATER — A fully-sealed onboard charger rated IP68 for waterproof protection. Survives brutal life cycle testing, including thousands of hours underwater in the harshest marine conditions.
• WHAT’S IN THE BOX — GENPRO10X3 30A 3-bank onboard charger with 72-inch DC cables and 3/8-inch eyelets, 72-inch AC cable (Type-B), and two mounting screws. Backed by a 3-year warranty and engineered in the USA.
