## Description

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: Excellent Battery Charger & Maintainer - I have a truck that mostly sits in the garage. Every time I need to back it out of the garage, the battery is dead. I know that just sitting isn't good for batteries, not to mention this battery is several years old. Now keep in mind, this is a large amp battery for a SUV, which was so dead, a turn of the key and I didn't even get lights on the dash. I stuck this little charger on it and it took a day and a half, but it charged completely. Ok, now I'm beginning to get a tad impressed. I have two of those old type chargers, you know the ones that after a while you can hear the acid boiling inside the battery, and the battery is getting really hot... you know the chargers that tell you not to leave it on your battery for any extended period of time as this might (will) damage the battery (possibly even start a fire). Well... no more. I'm a total convert now to using smart chargers, and this one seems especially good. I really hope I don't find some little something that breaks 6 months from now, cause I really like this charger! It seems very well designed and made and most of all, it works great. The only negative I can find, it has a single button to select one of several charging modes, and LED's to indicate which option you have chosen, and those LED's are pretty much self explanatory, as well as an advanced mode where you have to push and hold the single button to enter advanced charging mode. For example, if your battery is so bad, the charger cannot detect there is even a battery hooked up, you can tell it to go ahead and start charging anyway which is a really nice feature. As another reviewer mentioned, when you need to use some of the more advanced functions, if you've lost the booklet, well... good luck. The multi-language booklet briefly explains all of the options, what the LED's mean, and that's pretty much it, verbose it isn't.. It comes in a really nice packaging, like you're really getting something ( and you are), the unit itself seems well made and thought out, you would think a bit more of an effort would have been put into the manual. But, perhaps the product speaks for itself... and it does. And, after all most users will hook it up to their 12 volt car/boat/motorcyle battery, plug it in, select the regular 12v battery option, and that's all most will ever need. Once the battery is charged completely, the charger senses that, and switches automatically to just maintaining the battery. If you loose power while charging (or maintaining), this charger just picks up right where it left off, so there is no worries about pushing buttons or selecting modes, it knows what you were doing before, and starts right back up with doing it again. Am I glad I got it: Yes Would I buy it again: Yes.

## 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.

*by K***E on January 14, 2026*

Takes a while to fully charge my truck battery, about 3 days!! But it was easy to set up and understand. It's continued to work over the years I've had it and overall it does it's job and really does recharge the battery fully! Very nice little affordable product. Thank you!
