NOCO Genius GEN5X2: 2-Bank 10A (5A/Bank) 12V Onboard Battery Charger and Maintainer

The NOCO GEN5X2 is our most rugged, compact, and powerful 2-bank onboard marine battery charger ever—37% smaller and delivering 43% more power than the previous GENM2. Designed to charge and maintain two 12-volt batteries up to 120 amp-hours each, it supports all types of lead-acid and lithium-ion batteries, including flooded, gel, AGM, and deep-cycle. Each bank delivers 5 amps, functioning as an independent battery charger, maintainer, and desulfator. The GEN5X2 features selectable charging modes for each bank—12V, 12V AGM, 12V Lithium, and 12V Repair Mode—offering precision charging tailored to each battery type. A built-in thermal sensor adjusts charge based on ambient temperature, preventing overcharging in heat or undercharging in cold climates. It can even recover deeply discharged batteries down to 1-volt, or activate Force Mode to manually charge dead batteries down to zero volts. Fully sealed and IP68-rated waterproof, it’s built to endure the harshest marine conditions, with an anti-vibration mounting system for noise and shock isolation. Easy to install in any orientation—even upside down—this charger is certified to UL1236, ISO 8846, and compliant with 33 CFR 183.410. Included in the box is the GEN5X2 10-Amp 2-Bank charger with 72-inch DC cables featuring 3/8-inch (M10) eyelets, a 72-inch Type-B AC cable, four self-tapping mounting screws, a user guide, and a 3-year warranty.
