    NOCO GeniusTM On Board Marine Battery Chargers. Wicked smart chargers!

    The NOCO Genius is a smart, 8-step, fully automatic switch-mode battery charger. Its mission? To charge batteries faster than ever while restoring batteries to their original capacity.

    Here's how that's accomplished:

    Advanced 8-step Charger: The Genius' proprietary charge algorithm automatically diagnoses the condition of your battery charges when needed, recovers your battery to its original capacity and maintains your battery when not in use.

    90% Energy Efficient: Why does this matter? Because the higher the efficiency, the lower the power loss, which means a smaller and more versatile charger that requires less space.

    Rapid Charging Technology: Each NOCO Genius Charger comes with Rapid Charging Technology programmed inside. Its smart microprocessor and advanced high-frequency design charges batteries 2X faster than traditional linear marine battery chargers. Faster charging means less time recharging your batteries and more time on your boat.

    Variable Input Compensated: Rarely are AC line voltages at 120 VAC. Whether you're at a motel, a dock or even using a long extension cord, AC line voltages are going to vary. With Variable Input Compensation (VIC), the NOCO Genius Charger always delivers a 100% charge to your batteries.

    Without VIC, other battery chargers lose power and under-charge your batteries. And some chargers, when the VAC is above 120, will over-charge your batteries and cause permanent damage. Rest assured, the NOCO Genius automatically adjusts to varying AC line voltages to avoid all those issues... now that's smart!
