Designed for 6-volt and 12-volt lead-acid (AGM, gel, flooded, and deep-cycle) and lithium-ion (LiFePO4) batteries (up to 30 amp-hours), it is compatible with a vast array of vehicles, such as cars, automobiles, motorcycles, dirt bikes, scooters, mopeds, lawn mowers, ATVs, UTVs, tractors, trucks, SUVs, RVs, campers, trailers, boats, PWCs, jet skis, snowmobiles, golf carts, classic cars, and more; including automotive brands like BMW, Mercedes-Benz, Porsche, Bentley, Maserati, Lexus, Audi, Ford, Chevrolet, Corvette, Cadillac, Prius, Toyota, Subaru, Nissan, powersport vehicles such as Harley-Davidson, Honda, Yamaha, Kawasaki, Ducati, Indian, KTM, Husqvarna, Vespa, Polaris, Seadoo, as well as lawn and garden vehicles such as John Deere, Kubota, Toro and more. Featuring an integrated thermal sensor, the GENIUS1 adjusts its charging profile based on ambient temperature, ensuring optimal performance by eliminating the risk of overcharging in hot climates and undercharging in cold ones. It's capable of charging batteries as low as 1 volt and offers a Force Mode for manually charging completely dead batteries (as low as zero volts). With precision pulse charging, the GENIUS1 restores battery health by reversing sulfation and acid stratification, improving performance and extending battery life. Its advanced monitoring system allows for safe, indefinite connection, making it perfect for long-term maintenance. The package includes a 1A charger (120-240VAC), a direct wall plug-in, 110-inch DC cable with battery clamps and integrated eyelet terminals, all backed by a three-year warranty. Proudly designed in the USA, the GENIUS1 combines power, reliability, and convenience in a compact design to keep your batteries ready for whatever lies ahead.

    Excellent charger

    The NOCO Genius1 is a compact, reliable little charger that does exactly what it promises. It’s perfect for maintaining smaller batteries like those in motorcycles, lawn equipment, or seasonal vehicles, and it can safely be left connected without worrying about overcharging. I really like the safety features (spark-proof, reverse polarity protection) and the fact that it can even bring back low-voltage batteries using its repair/force mode. That said, at only 1 amp it charges slowly—great for maintaining, but if you’re trying to revive a large car or truck battery, expect it to take quite a while. The LED indicators are clear enough, but a digital display with more detailed feedback would have been nice.
