Meet the all-new GEN5X1 by NOCO
Similar to the original GENM1 12V/4A charger, only better. It's 51% smaller and delivers 43% more power. It's one of the best performing onboard marine battery chargers NOCO has ever made. A one-bank onboard battery charger rated at 5-amps for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. Independently charge and control each battery bank with selectable charging modes - including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode - for all types of lead-acid and lithium-ion batteries.
Rated to IP68. Fully-sealed charging.
The GEN series is 100% waterproof and designed to withstand hour underwater. The GEN5X1 is an on-board charger built for extreme conditions.
Powerful, efficient, and compact
A clever mix of engineering and design pack a powerful battery charger into a tiny footprint. The GEN5X1 uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging. The onboard microcomputer precisely controls the charging to minimize power loss to crate an incredibly compact form factor.
Do more with one charger
A multi-functional design allows you to charge 12-volt lead acid and lithium-ion batteries of multiple chemistries (Flooded, gel, maintenance-free and AGM batteries) and types (Starter, deep-cycle, marine, and more).
Charge dead batteries. Down to zero volts
The all-new start-voltage sensors allows the Genius GEN charger to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on force mode to detect and charge batteries all the way down to zero volts.
Thermal compensation. Precise charging in any climate.
The new integrated thermal sensor automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, limiting the chance of under-charging or over-charging, providing a more accurate and fully charged battery. Avoids under-charging in cold weather down to -4°F and avoids over-charging in hot weather up to 104°F.
Bring dead batteries back to life
The GEN5X1 automatically detects sulfation and acid stratification. If any is found, the charger will automatically repair and reverse the damage done to the battery, extending the usable life and increasing the performance.
Completely automatic, 24/7 charging
From start to finish, the GEN5X1 is completely automatic. No special modes or technical knowledge needed; any battery will be safely charged. Detect damaged batteries and intuitively repair them. Actively monitor long-term battery maintenance and extend battery life. Continuous use without any intervention required; zero risk of overcharging your battery.
Understand this charger is usually adequate for maintenance of most automotive batteries. Vehicle computers normally consume under 4 Amps of power at a time while parked. Also, while safe for AGM, the GEN series chargers do no fully volt AGM and AGM + batteries for their optimum charge. They do provide adequate charging for AGM types.
I purchased the GEN1 Mini for its smaller size and water resistance to use in a customized 1981 GMC pickup. I use a sealed lead acid battery in this truck, and there is only a very slight parked battery drain due to a remote start and security system on the pickup.
A big plus is this charger/maintainer shuts down when not needed - resting the battery. It also restarts on its own as needed, and the multiple charging stages see to a good charging balance for improved battery health. The discontinued BatteryMINDER 12151 under-hood charger/maintainers were good, but the GEN 1 smokes them in performance. This means even longer battery life with religious use of the GEN 1 Mini while the vehicle is parked.
Use this charger to provide battery maintenance for emergency generators
