Product description

Meet the GENIUS1, one of our most powerful, highest-performing, energy-efficient, and compact portable universal battery chargers yet. The GENIUS1 is a 1-amp (15-watt) - 100-240VAC 50-60Hz - 6-volt and 12-volt heavy-duty battery charger, battery maintainer, trickle charger, float charger, and battery desulfator for up to 30 amp-hours. It's designed to charge and maintain all types of sealed lead-acid and lithium-ion (lifepo4) batteries, including flooded, gel, maintenance-free, AGM, SLA, VRLA, as well as automotive, marine, RV, powersports, and deep-cycle batteries. Its advanced battery repair regenerator mode uses slow pulse reconditioner technology to automatically detect battery sulfation and acid stratification, restoring lost battery performance for extended battery life. It can be used and stored almost anywhere - home, garage, mobile, bench, or in car - to charge and maintain any battery - even plug in through your vehicle's 12V auxiliary cigarette lighter port. Its next-generation charging regime utilizes fast charging microprocessor technology to rapidly recharge batteries without any manual intervention. It's a completely automatic, worry-free, professional, and commercial-grade intelligent battery charger with zero overcharge. Designed to be dual purpose - both indoors and outdoors - providing weatherproof and waterproof protection from the outside elements during any time of the year, including winter. Its X-Connect battery connectors - better than SAE - allow for quick-connect permanent connection or connecting directly to the battery terminals. A digital display provides the charging status and tests diagnostics for multiple conditions such as a dead battery, bad battery, reverse polarity, and more. And it's compatible with all types of gas and diesel vehicles, including cars, automobiles, motorcycles, dirt bikes, scooters, mopeds, lawn mowers, ATVs, UTVs, lawn tractors, trailers, trucks, SUVs, boats, campers, RVs, jet skis, PWCs, wave runners, snowmobiles, 4-wheelers, generators, golf carts, classic cars, including BMW, Mercedes-Benz, Porsche, Bentley, Maserati, Lexus, VW, Audi, Ford, Chevrolet, Corvette, Cadillac, Jeep, Prius, Toyota, Subaru, Nissan, Honda, Harley-Davidson, Suzuki, Yamaha, Kawasaki, Ducati, KTM, Indian, Husqvarna, Vespa, Polaris, Seadoo, John Deere and more.

5.0 out of 5 stars I can't recommend this enough.
Reviewed in Canada on January 12, 2024
Verified Purchase
I've used this charger to bring 3 batteries back from the dead now. 2 AGM's and a lead-acid (all automotive 12v).

Did it save all the batteries I put on it? No. 2 were simply too far gone. But 3 out of 5 ain't bad! That's at least 300-450$ worth of batteries I no longer have to buy.

Does it sometimes take a little while to charge? Yeah, by design. That's the whole point of a trickle-charger. You want it to be slow as that's what'll revive your dead batteries.

I can't say enough good things about this charger. It's well designed, high quality, easy to use (the only thing I haven't figured out is how to force a charge), and very reasonably priced.

Stop researching and comparing specs and prices. This is the trickle-charger you want to buy. Period.

5.0 out of 5 stars Works well, but you need an extra cable to make it easier to connect. (Amazon carries them)
Reviewed in Canada on January 27, 2024
Verified Purchase
I bought this because my car wouldn't start (2020 Corolla) in very cold weather as I am old and do not drive it very much. The mechanic at my dealership did not install it, as he said it meant me hooking it up to the battery every time I wanted to use it. Suggested I buy a cable with a connection plug on it, so I could use my extension cord. I ordered the cable from Amazon and took it in the next day, and they installed it. However, I was a bit shocked to find that to connect the extension cord to the new cable I had to pop the hood every time, and then again to disconnect it. My mechanic showed me how to do it (I never had) and made sure I did it several times, so he could see I knew what I was doing. Brought it home and popped the hood and connected the extension cord and the battery charged up just fine. I have gotten used to doing it now, but anyone old, like me, should be aware of this. I never read the readings on it, so can't say anything about them, the mechanic adjusted it and I don't touch anything. I just plug it in when it's going to be very cold, or I am not using the car for a few days.

My 2005 Avalanche did not like the cold and little use so the battery got very low, would not even turn over. It can now run. Note, I also have a 5 amp charger I use on my RV. The amp fuses are different so do not mix the clamp.
cables up or the 5amp charger will blow the 1 amp charger cable fuse (2 amp fuse). It did take 3 days to get a green light on my dead battery in my Avalanche.

Recommended by a friend, I use this to maintain the battery on an old Volvo and Mini Cooper JCW whenever they won't be used for a while. Seems to work perfectly: cars start right up even after being garaged for a week, a month or more. Easy to connect, simple indicator light, and packs up in a small box for storage, and a reasonable price. Does just what it's supposed to do.
