    • 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

    • 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

    • Great charger, so easy to use.
Size: 10A
This charger is a life saver. We were having no luck with our old charger when trying to revive the RV batteries that we just bought last year. They got too low and couldn't get them to take a charge. This charger has a repair ability which is a life saver. It's a great compact size and it actually restored life to our batteries. ... show more

    • The Only Charger You Need: NOCO Saved Me $2,000 and Weeks of Waiting!
Size: 10A
I cannot recommend the NOCO Genius10 enough. After a truly awful experience with an expensive, useless charger (the JMR), the NOCO was an absolute lifesaver for my 2022 Porsche Cayenne. My car has a specialized Lithium (Li-ion) battery, which can be difficult to charge with standard equipment. The worst part? The dealer quoted me $2,000 to replace the dead battery, and because it was a special order, the part was on a 4-6 week back order! I was looking at a massive bill and weeks without my car. The overpriced competitor (JMR) completely failed to charge or repair my battery—even after days of being plugged in. The NOCO Genius10, however, handled the challenge with ease. It has modes to work with multiple battery types, including Lithium, Lead-Acid, AGM, and Marine, and successfully not only fully charged the battery but also successfully repaired it! This charger is proof that you don't have to spend a fortune to get top-tier performance. For less than half the price of the faulty unit I initially bought (it cost me around $80), the NOCO is incredibly versatile. In addition to its multi-chemistry capability, it serves perfectly as a trickle maintainer. This is ideal for keeping the battery topped up and healthy during the times my Porsche is parked in the garage for several days. Stop searching and buy the NOCO Genius10. It's affordable, reliable, and actually works on tough-to-charge batteries like Lithium. This brilliant piece of engineering saved me $2,000 and weeks of waiting! ... show more
