NOCO GEN5X1 12V 5A 1-Bank OnBoard Marine Battery Charger & Maintainer
- MEET THE GEN5X1 — 37% smaller and 43% more powerful than the GENM1. It’s our most compact and advanced onboard charger yet—engineered for peak performance in the harshest marine environments.
- SINGLE BANK — A one-bank onboard battery charger rated at 5 amps total - 5 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 — GEN5X1 5A 1-bank onboard charger with 72-inch DC cables and 3/8-inch eyelets, 72-inch AC cable (Type-B), and two mounting screws.
The NOCO GEN5X1 is a fully-sealed, waterproof onboard battery charger rated at 5 amps, designed for 12-volt lead-acid and lithium-ion batteries, including flooded, AGM, gel, and LiFePO₄ chemistries. It’s 37% smaller and delivers 43% more power than the previous-generation GENM1, making it our most compact and advanced charger yet. With a single dedicated charging bank, the GEN5X1 offers precise charging and maintenance for one battery with selectable modes—12V, AGM, Lithium, and Repair Mode—tailored to maximize battery health, performance, and longevity. An integrated thermal sensor automatically adjusts the charge based on ambient temperature to prevent overcharging in heat or undercharging in cold conditions. For severely discharged batteries, Force Mode allows manual charging down to zero volts—ideal for reviving deeply neglected batteries that most chargers cannot detect. Built for the harshest marine environments, the GEN5X1 carries an IP68 rating and has passed extensive life cycle testing, including thousands of hours underwater. Its streamlined mounting system enables fast, secure installation in any orientation—even upside down—with an integrated anti-vibration backing to minimize shock and noise. The GEN5X1 includes 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide.
