The GENIUS1 is the ultimate all-in-one solution for battery charging, maintenance, and restoration, delivering 35% more power in a 35% smaller design compared to its predecessor, the G750. 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.

Review: Very compact, but adjustable, charger for all battery types! - Great little 'trickle' charger, for any vehicles that have to sit around (in storage, etc.), or in challenging weather!! I have one, on my RV, stored in a chilly climate, and it keeps my battery in top condition! Bought another one, to use here at home, with another 'weekend' car, that has some minor issues with a slight battery drain. It is also very very adaptable, because it works with older, and newer battery types, and charges at appropriate intervals in order to not damage those newer type batteries.
Review: I Really Like this Item - I will try to be as honest as possible because I depend on other people's reviews and feel I want to help the best I can: Item arrived just as described. This appears to be a well-made and quality item. Every Winter I must totally disconnect my Riding Mower Battery to keep the Engine clock on the mower from wearing it down. In the spring I must hook the battery back up, cross my fingers and hope the battery has enough charge to fire the engine up. I decided enough is enough and invested into this little gizmo. WOW am I impressed. I got the 1 Amp because I do not need it for charging dead batteries but just to maintain the mower battery over the winter time. I also picked this one for the mower because it plugs in directly. I did not wish to have a smaller cord run across my shop floor all winter while I walk on it. SO, I got a 15' extension 12/3 Heavy Duty cord to run to the mower. I plugged this item into the cord and hung it on the back of my Zero Turn mower. Then I ran the battery clips to the battery posts. This way I'm walking on a thick heavy duty extension cord all winter, which will be fine. I can even roll my wheelbarrow on it without incident. My mower had been sitting about one month unused when I decided to purchase this item. Once plugged in, it did everything exactly as expected from me watching You-Tube videos and such. I saw it was charging and left it alone for a few hours. I came back and had a solid Green light on meaning it is now just maintaining. I have checked it daily and it's working great so far. Now I will not need to disconnect my mower battery ever again AND the battery is fully charged when I'm ready to start it up again this spring. I will NOT be using this item during the spring or summer months because I run my mower once or twice per week as a normal. I Recommend. Good Luck.

## Questions & Answers

**Q: How does noco 1-amp battery charger compare to axtra 3.6-amp battery charger?**
A: The NOCO GENIUS1 is a 1-amp battery charger that can be used for a wide variety of batteries (including 12-volt lithium, and 6-volt lead-acid). It automatically maintains the battery once full, and can help recover sulfated and stratified batteries.

**Q: Should i use noco battery charger with axtra power strip?**
A: If youre using the charger outside I would use a protected power strip or plug into an outdoor outlet with a gfci.  I run a 25' extension cord to my car to use my Noco chargers, i have the Genius 1 and the Genius 2.  My outdoor power outlet does not have a gfci, its just a regular outlet, so i use a 3' protected splitter plugged into the outlet.  My only concern is if its raining out, which has happened while i was using the charger.

**Q: Does 3.6-amp axtra battery charger maintainer better than noco 1-amp battery charger?**
A: I have both of these chargers. AXTRA car battery maintainer is cheaper, and it worked better than NOCO genius 1 charger. Hope this information helps, here is the link to product: www.amazon.com/AXTRA-Fully-Automatic-Maintainer-Motorcycle-Tractors/dp/B08T7V4VQC

**Q: It looks like axtra car battery charger is better than noco genius 1 charger. isn’t it?**
A: This is a battery maintainer/charger. It gets the battery up to full charge and keeps it. A charger will over charge the battery if not monitored.
