???? Final Verdict: If you're looking for a powerful, intelligent, and dependable battery charger, this is the one to get. Highly recommended for both casual users and automotive enthusiasts. - JohnWorked Exactly as Advertised and did a wonderful job of charging my Jeep's BatteryI recently tried out the NOCO Genius10 Smart Battery Charger on my Jeep Rubicon, and I have to say I’m pretty impressed. Since I live in a townhouse, I powered it up using my Jackery Power Station, which made it super convenient—no need for a long extension cord or anything like that. It took about three hours to bring my Jeep’s battery from roughly 40% up to about 90%, which is pretty much exactly as advertised. Overall, it was really easy to use and did exactly what it promised, so I’m definitely happy with it.

I have to say. This is by far one of the best products I have used in a long time. It just WORKS. And just as the Manu said it would. It's sad that I even have ot say this but that shows you the state of consumer products.
NOCO really hit this out of the park with ease of use, reliability and hardware. It reminds me of Apple Hardware with the build quality. This is being used with my 23 Rubicon. Its not my daily driver - I normally use it when I have a drone contract and am out in the middle of nowhere. So, the battery does not get fully charged and sits quite a lot.
I purchased the "NOCO GC008 X-Connect M10 XL Eyelet Terminal Accessory" instead of using the Terminal clips. For a Jeep, I have to unlock the hood latches, open the hood, connect the clips and then close the hood until its charged. Without a garage this can be a headache with weather. The Eyelets solve the problem. I ran a 14Guage wire from the battery to the floor inside the cab. This way the cable is always connected and all I have to do is plop the Power Station on the seat and plug in the Genius 10.
I had a chance to try out the system today and wow, talk about easy. This is truly a life saver and knowing my battery is topped off and maintained makes all the difference for me.
--NOCO now has a customer for life. -- - Raymond W.A must have for every car enthusiastHonestly I thought the battery repair function was gonna suck and not work but MAN WHAT A SAVIOR!
Worth the money based off that singular feature alone!
I always buy the best batteries on the market for my fleet of vehicles, and yet somehow some way somebody forgets to plug in the maintainer or leaves the headlights on or keeps starting and shutting the car off every 2 minutes for absolutely no purpose other than to hear the exhaust GRRR!! Of course these people end up making my batteries useless after about 3 to 6 months time. I was shelling out hundreds sometimes thousands for new batteries in these vehicles every year. Well, Not anymore! This noco genius 10 took a battery that couldn't hold more than 4 volts, wouldn't charge from the alternator and not only fully charged it in a few hours, it also repaired it in under 12 hours and now that same battery can hold voltage for over a month without dropping below 12.68v under load with the vehicle off.
When I tell you this thing has saved me thousands, I mean it.
I'm buying more.
I wish the units with more power / amperage were cheaper to buy. 10A just isn't enough for many vehicles I have. But I'm not about to shell out upwards of $800 for one 50A charger. Instead I'll buy a couple more of these and try to get my people to take better care of the batteries.... (yeah right)
Very compact, Very sturdy, Durable, and Lightweight.
The included cord length could and most definitely SHOULD be longer by many feet. Even the extension cable you can buy isn't very generous, Instead I've ran permanent outlets to each bay specifically for these chargers.
