    • Pretty neat device, very capable as well
Size: 10A
I have a battery charger made in the 1970s, inherited from dad that passed away in 2011. It was time for another one, and I was going to buy another Schumacher that weights about 15 Lbs. Was ready to pull the trigger and decided to see if something better was out there, thus buying a Genius 10 instead based on YouTube reviews. The Genius 10 was much larger and heavier than how it looks in the picture. The build quality is really good in my eyes, looks like tough ABS polymer, very nice cords with that good feeling wire jacket insulation. The new clamps are nice looking and very practical to me. It's heavy and awkward to store, so I bought the Noco case as well; I thought the other case was too small in size. I ran some test with it, on a 12V Honda Lead Acid and Group H8 AGM battery and was happy the results. It was more intuitive than the 1970s version I have with 30 amp boost that is scary to use. What I like with Noco or Genius, it's several tools in one unit, so every 3 or 4 months, I can use the Genius to check the status of all my batteries, well that is the plan at least. One neat thing, using the 12V output to keep a battery online while changing a battery, so the cars computer keeps running and doesn't reboot from removing the battery causing weird things to happen. I have no regrets in my purchase and bought the case to enhance it more. I think the price is reasonable as well considering what a $100 buys today. ... show more

    • If your thinking about it buy it .!!!
Size: 10A
Since buying this I can honestly say it’s the best money I’ve spent .! It fits perfectly on different cars, it’s super easy to store away when not in use. It’s small and light (yet powerful), it’s pretty basic knowledge to use it the functionality is almost dummy approved 😂. I won’t be needing a replacement car battery for quite some time as this has now brought back 2 completely different car batteries from being deeply discharged in about 24hours .! The battery indicator is super easy to read and keep up with you know when it’s not charged and you also know when it is fully charged. I’ll be keeping this around in my garage for a very long time. ... show more

    • Saving money! So far so good.
Size: 10A
Review Image by Steven Beckman
So far so good. I purchased the genius 10 in hopes to save some of my batteries around the house and save a little bit of money in the long run. I have everything from cars trucks, RVs, dirt bikes, generators, and everything in between. I use this specifically on my generator, which uses a 12V sealed lead acid battery. I had the generator sitting for a few months in the storage container where it went through some hot and cold Cycles needless to say my lack of maintenance the battery was dead and would not turn over the generator. The generator is a 9000 W champion. I took the battery out and I did not measure the voltage prior to, but I put it on another brand “smart charger”. That brand rhymes with “shoemaker”. That charger ran for a little bit, but then aborted the charging cycle because it said it was bad. I then put that battery on an old-school charger not a smart one one that’ll just run no matter what and left it on for a few hours and then reinstalled the battery again it would not turn the generator over. I pulled the battery out and it measured 11.5 V and I hooked it up to Topdon battery analyzer, and it said the battery was bad. I purchased the Noco genius 10 not just because I wanted to try it on this but because I know all around it seems to be a good charger. As the Noko instructions said, I hooked up the battery and ran it through a normal charging cycle prior to using the repair mode. The normal charging cycle only ran for about 10 minutes before it said it was fully complete. I hooked up my battery analyzer again and again it said it was bad. I then ran the 12 V repair mode on the Noco and it ran for about four hours. After the repair mode was complete I hooked it up to the battery analyzer again and it still said it was bad, but I wanted to give it a shot in the generator. Oh, and I forgot after the repair mode the voltage on the battery red 12.6 V and it held 12.6 V overnight so that was a positive sign. I put the battery in the generator and it started flawlessly. So I spent $99 on the Noco charger and saved myself $40-$45 from buying another battery for my generator so it seems to already be paying for itself. ... show more

    • Easy to Use Charger Helps My Ford Maverick Avoid Sleep Mode
Size: 10A
I bought this charger for my new Ford Maverick Hybrid to help prevent the 12-volt battery from draining and causing the truck’s battery management system to enter sleep mode. It is compatible with the vehicle’s AGM battery and keeps the charge maintained, which is especially helpful when the truck is used mainly for short trips or parked for long periods. The charger is easy to use, with straightforward connections and settings. It runs automatically and shuts off once the battery is fully charged. ... show more

I ordered this for use on my 2024 Land Rover Discovery Sport S. This charger works with 12V AGM Batteries , which the Land Rover has. I gave it 4 Stars instead of 5. Due to lack of instructions, though I was able to obtain all the information from Copilot. It works great and will be a good garage tool. ... show more

    • Just added the NOCO Genius 10 to my large selection of NOCO chargers - love reduced charging times
Size: 10A
This is a review of the NOCO Genius10: 10A 6V/12V Smart Battery Charger. I have used NOCO battery chargers for years including the following: -- Genius Gen Mini 1 -- Genius G750 -- Genius G1100 -- Genius G3500 -- Genius 5 -- Genius 10 (as of one month ago) I have had only good experience with NOCO battery chargers. I recommend them. I purchased the Genius 10 purely to reduce the charging time on a car battery. While my Genius 5 has been perfectly fine for car batteries, the Genius 10 charges roughly twice as fast as the Genius 5. I am pleased with the reduced charging times. But if you don't mind a charging for 12 to 14 hours then the Genius 5 will be fine for you. The Genius 10 weighs about 3.3 pounds, whereas the Genius 5 weighs only 1.5 pounds. The NOCO Genius 10 charger may be used to charge the following battery types, either 6-volt or 12-volt: (1) lead acid; (2) AGM; or (3) lithium. The Genius 10 also has a “Repair” mode that may bring a damage battery back to life. The Genius 10 may also be used as a power supply. Soon after I received the NOCO Genius 10, I used it to charge all of my 12-volt batteries, including the following: (1) a deeply depleted large car battery in a seldom-used car; (2) 20 amp-hour lead acid batteries; (3) 22 amp-hour AGM batteries; (4) 35 amp-hour AGM batteries; and (5) 45 amp-hour lithium iron phosphate batteries. I am very pleased that this charger works great with all of our 12-volt batteries. I do not have any 6-volt batteries to charge. In the past, I’ve used “Repair” mode with my Genius5 charger, but not yet with the Genius10. I like that NOCO Genius chargers are very easy to operate. Unless you have extraordinary eyesight, I highly recommend that you find the user manual for the Genius 10 online, since the printed version that comes with the unit uses very small text. I think most folks will only need to read the user manual one time. Although you should probably review the instructions for “Repair” mode immediately before using it. Tip: The first time you use the Genius 10, it will be in “Standby” mode. That is, it won’t do anything. For the first use, you need to manually select the operating mode. For example, for a standard car battery, you would press the “MODE” button until the “12V” light is lit. Keep pressing the “MODE” button if you want the other modes (like “12V/AGM” or “12V/Li”). If you miss the light you want, just keeping pressing the "MODE" button until it cycles back to what you want. You can easily find the estimated charging times for any NOCO battery charger with a web search. Of course, charging times vary based on battery capacity (amp-hours), depth of discharge, and health of the battery. The NOCO Genius 10 can charge a standard car battery in 6 to 12 hours, about half the time of the Genius 5. You may need an extension cord to use your NOCO Genius 10 on your car or truck. I use a 25-foot 3-prong heavy-duty extension cord. ... show more

    • Solid!
Size: 10A
Purchased the NOCO Genius charger in hopes it would resurrect my battery. Un fortunately, it did not save my battery, but I cannot blame that on the charger. The only complaint I have is the lack of instructions. They were not minimal, there were none at all provided with the unit. Luckily, able to look on line and find plenty of videos, however, this does not negate the need for an instruction and care pamphlet. The unit feels solidly built and works as expected. While it did not resurrect my battery as it claims it can do (not in all situations), mine was 5 years old, lead acid and probably just to far gone for help. However, it is doing a great job charging my marine battery and using it to keep it charged until used again. I like it. Much more compact than the older styles and easily able to mount to a wall or post as a charging station. I would definitely buy again. ... show more

    • Riptide pool vacuum owners, look no further!
Size: 10A
I just bought this after researching what is the best battery charger or maintainer for owning a Riptide pool vacuum system. This is for personal use and not running a business. Advice for new pool owners or even existing ones, do not buy a junky 500-1500 dollar pool robot, but a hammerhead or Riptide vacuum. Long story short I bought this maintainer to charge the vacuum battery and maintain it between uses. Charged it in no time and I also use this for my Yamaha 700 ATV. Fantastic unit. Only regret is before I opened this, I didn't test it on an ATV battery that died on me to test it's recovery mode. Chance are that I gave the kid at Advanced Auto parts a free ATV/motorcycle battery because if he had one of these NOCO 10s, chances are he saved the battery and got new life into it. Cant go wrong with this especially for the fast charging, force recharge mode, and versatility to charge, maintain, and breathe batteries back to life. Just one more thing, First time charging the battery after sitting idle for 3 weeks and 2 uses in my case and charged it to full literally in 5 min. I like the unit for keeping the battery at full between uses and not overcharging costing me $300 for a new battery. Well worth the money for less worry and hassle. Hope this helped someone with whatever they were looking to use this for. Also cable length is more than sufficient. Im sure there's an extension option if needed too. ... show more
