NOCO GENIUS1 Fully Automatic Temperature Compensation Reviews Summary

Battery Charging Performance

Pros:

• "I purchased the Genius 1 specifically to charge my motorcycle's Shorai lithium battery, and it gets the job done and is simple to use."
• "This little powerhouse works great. It recharged my depleted car battery in an extra vehicle I don’t use much and is maintaining it."
• "After some research, connected it to the battery and left it. After about three days the battery was fully charged and my car started up with no problem at all."
• "I have used it on a bunch of batteries. The little led that fades in and out when it's charging is pretty cool."
• "I used it to maintain my lawn tractor battery and it did a great job - until it stopped working. No lights, no output."
• "I have used battery tender brand maintainers for years, we use them at the shop daily. I thought I found a good choice for a 6v battery."
• "Purchased Product in September 2021. Hooked up for winter. Noco Charger initially was showing RED. After checking on it status was green for several months."
• "It's been COLD COLD for the past week and my car battery seemed to struggle a little when starting. Thursday it said nope all together. ...i ordered noco genius.. got it at around 9/10 plugged it up to car battery checked on it 6 hrs later and it was ready car started with no problem."

Cons:

• "I received the charger and hooked it up for trickle charge on an already charged battery in a car I don’t drive much. I went to start the car a month later and the battery was dead."
• "I had lent it to a friend to use before I had used it. He told me it didn't work. The last time I left it on for 35 minute and it charged the battery enough so the the interior lights would go on and that's about it."
• "I had a car battery that would not stay charged enough to start in cold weather. After half a day parked, I would have to jump start it. I bought this device to at least maintain some kind of minimal charge on the battery until my repair shop appointment to get it replaced. It did not work at all."
• "I just got the charger/maintainer and went to use it. I read the instructions and hooked it up as instructed, plugged it in and got the indication that I had reversed the polarity. I double and triple checked that I had it right and still it showed that I had reversed polarity."
• "The first time I used it I successfully charged a completely dead car battery. What I didn't like was the lack of a good owner's manual and the fact that it did not work as explained."
• "The instructions and packaging that come with the item have no mention of desulphating capability. One other reviewer apparently checked with the company who replied they do not make chargers with desulphating capability."
• "I just ordered Number 3 of this model of battery chargers. The first one lasted 22 months which was OK for the price. However, the second didn’t make it to six months and that is not OK."
• "Reviews end here."

Product Design and Features

Pros:

• "I got this NOCO GENIUS1, 1A Smart Car Battery Charger at a decent price… it works well as a battery topper, to maintain a battery during storage or infrequent usage."
• "I have waaay too many batteries in the garage! It's important to me that the tractors, bikes, ATVs, etc., are ready to go when I am. Keeping them on trickle chargers year round has made some of my lead acid batteries last more than a decade!"
• "Great product with a nice set of features. My only issue is the instructions aren’t that well-made and the fact that it uses lead wiring! Other than those two issues great product."
• "This is a great little battery trickle charger. Keeps it full and helps prevent batteries from going bad while sitting for extended periods. The price is insanely good for the quality."
• "I bought several to keep my batteries alive through a Minnesota winter. I used them on a stored car, a lawn mower, and an emergency generator. All started right up in the spring so I guess it worked."
• "This thing is so compact I can fit it in my battery housing with my smallish lipo battery I have on my harley. My battery had drained down to 0 and I couldn't find my lithium battery charger so I thought I'd give this a try."
• "The packaging was fantastic. Someone spent a lot of money on the complex trendy packaging."
• "I am satisfied with how the battery maintainer works. I really am not pleased with Nick using its own proprietary connector instead of an SAE connector."

Cons:

• "It is a small 1 amp maintainer, so it’s not fast."
• "Very important note, unsure why this comes up when you search portable or why it says it's portable, it's not! It must be plugged in to the wall to work and is therefore, not portable."
• "I'm sure most things about this charger is fine, but noco is starting to use their proprietary connection instead of standard sae connections."
• "The first time I used it I successfully charged a completely dead car battery. What I didn't like was the lack of a good owner's manual and the fact that it did not work as explained."
• "The packaging was fantastic. Someone spent a lot of money on the complex trendy packaging. Pity the charger had essentially no instructions on how to use it."
• "Trying to keep my Mazda CX-5's battery from going dead since we drive it about twice a month. I plugged it in and set it to 12-V battery. The charge LED flashes red then green and repeat... at the same time, the 12-V battery icon also flashes white. After about 20 secs, it stopped and nothing happened."
• "I bought this for my kids classic cars. Was just expecting a good slow charger. Nope, this thing works just as good as a full sized craftsman charger we have and doesn’t take up space."
• "I bought this because it was recomended to buy it in bulk with the 55amph deep cycle battery for a trolling motor. It looks good and works as described."
