## 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: Little Miracle - Okay, I did NOT expect this little thing to work, but it did and might for you IF you have patience. My Grandfather who was MoAT (Mechanic of All Things) owned back in the day what I thought were REAL chargers, they were so big and heavy they had to be put on wheels and rolled around, they had giant switches that'd illuminate and while I'm probably purely imagining this they were plugged into 220-volt outlets. This thing fits in the palm of my hand, just as pictured, smaller than most mobile phones. "Huh," I said, "this should be comical." I hooked it up and, as others have said, figuring this thing out is NOT straight forward, the instruction manual is weak to say the least, the good news is, as I found, there are many intrepid experimenters who, like me, bought it on a whim and did some trial and error which it'd seem 99% of them got the thing to work to their needs, just like me hence, I'm taking the time to write this review. What this lacks in coherent features or instructions it makes up for it in the end by eventually (boy I mean eventually) getting the job done, for that honestly I'm giving it a generous five stars, because it did what I wanted it do against all odds, just like the Phil Collins song. ("Just take a look at my car now, 'cause it's finally starting here.") To get the to point, this took TWO WEEKS to charge a completely dead battery in a completely dead system. If it'll help anyone I own a 2000 Lexus RX300 that is, in fact, drinking age, if I could find a small ute-friendly bar to have a couple with me of which, in terms of trusty old friends, this boring beige over beige has been one of my best now with over 270,000 miles with no reason, per the Lexus dealer, to give up the ghost before 300,000. Toyota quality and then some with only wearables and maintenance needed BTW, the car has only had one issue, eating car batteries every four or so years. Being a cheap bastard and Lexus parts are pricy I've chosen battery over a slightly-off generator which brings us to the recent hullabaloo and the need to be the Noco Genius, though it'd prove not straightforward as I hoped. Hooking up the Noco Genius you get a slowly blinking light, like a heartbeat, that will tell you nothing really. Also there's a force-charge setting where you hold the button (there's only one button on the whole thing, this thing is basic) it supposedly will force a charge into a battery... this doesn't work, at all. After some digging it supposedly only does this if a battery is below some arbitrary limit which, my battery was completely dead, kaput, nada, force charge only made the 6V light go on which, apparently, is what others experienced. Point being, don't hold you breathe. I kept trying to charge the battery but it didn't budge, didn't budge, didn't budge, then I had a thought and said to myself "self, what if I unhook the battery, THEN charge it?" As in, is it because it's also hooked to my car hence current is going other places? Mind you, this thing is only one (1) amp, that's very little, if you're looking for a quick charger or something to charge and jump your car, this ain't it, have you seen the size of this thing? Ha no, no, but it will trickle, very slowly, a charge into your battery... if it's not hooked to the car. Listen, some people this may work when the battery is not hooked up and, in fact, I hooked my battery back up AFTER this thing actually worked and then hooked up the Noco to it and it did, in fact, go from red blinking to green, sooo, yeah, that happened. But I'm burying the lede here: The Noco charger worked for me but ONLY after it was hooked to the battery without being connected to the car. Total time to charge the battery not hooked to the car? About 36 hours. Great? Eh, there's a pandemic, I'm not really going out much so had time on my hands, not to mention my wife's car. In summation, IF you have even a completely dead battery or run down battery and IF you don't have to go anywhere in the next two days and IF you're comfortable unhooking the leads from your car to your battery so that it'll only be charging the battery itself this Noco Genius is, er, uh, genius! It really works! It works and for the cheap cheap cheap money its worth every penny. If this thing cost even 50% more I'd be taking down stars but this thing cost less than a steak dinner (back when I ate steak) so suffice to say it got my battery charged all the way up, hooked up to my car and after the computer was all "what the... ??? Was I in a coma" my car fired right up and ran, I even drove it around a bit. This would be a good thing to own for just-in-case as its just in case money. If you have any situation close to mine, get this trickle charger, if you need the big guns, well, open up your wallet and say ah. Luckily most of us, probably 99% of us, if your battery is run down, this will do the trick. Best of luck!
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.

## 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.

### ⭐⭐⭐⭐⭐ Easy to use, great sizing and works great!
*by T***K on January 28, 2026*

I bought 2 0f these and wish I'd bought 3! What a nice little easy to use maintainer. I tried it on all my vehicles, tractors and ATV batteries. Several of these get used regularly but not daily. I was amazed that they needed topped off as much as they did. Red light shows charging, then when they are getting closer to full charge, the green light pulses doing battery optimization, DE sulfating maintenance. Full green means fully charged. Very simple easy to use, just go thru the mode button and select your type of battery. Just a note on big batteries it took several days for the full green light
