NOCO GENPRO10X4: 4-Bank 40A Onboard Marine Battery Charger | IP68

Meet NOCO GENPRO10X4

The GENPRO10X4 is a compact, high-performance onboard charger designed for demanding marine setups. Delivering 40 amps total across four independent banks (10 amps per bank), it can simultaneously charge up to four 12-volt batteries. It supports a wide range of chemistries, including lead-acid variants—flooded, AGM, and gel—as well as lithium options such as LiFePO4, making it adaptable for varied systems on boats, yachts, and other watercraft.

Each bank operates independently, enabling you to charge different battery types, chemistries, or states of charge at the same time. With selectable modes for 12V, 12V AGM, 12V Lithium, and 12V Repair, the GENPRO10X4 delivers precise, tailored charging without the need to juggle multiple chargers or adapters. A built-in thermal sensor automates charging профiles based on ambient temperature, helping prevent undercharging in cold conditions and overcharging in heat, so your packs can perform reliably in changing weather.

For deeply discharged batteries, Force Mode provides manual charging control down to zero volts, a feature designed to recover neglected packs that other chargers miss. The unit is engineered for rugged marine use, with an IP68 waterproof rating and extensive life-cycle testing that simulates real-life marine submersion and operation. Its compact footprint and flexible mounting system support fast, secure installation in any orientation, including upside down, while an anti-vibration backing minimizes shock and noise during rough seas.

What’s in the box reflects a straightforward install: GENPRO10X4 unit, 72-inch DC cables with eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. The charger is backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410 for marine ignition protection and safety compliance. This combination of power, flexibility, and marine-grade durability makes the GENPRO10X4 a versatile option for multi-battery systems on watercraft of various sizes.
