Review: Great value and good charger - Works great, easy to use and use it mainly to bring my car battery back to full strength as I don't use it that often. I like the mounting bracket. Mounted it on my wall, but I did add a spacer underneath it because the charger gets pretty warm/somewhat hot, thus allowing air flow all around it. The small size & weight is great. The alligator clips are very good and adhere to the battery very well. Its obviously slower that my large 10 amp charger as should be expected, so if your looking for faster recoveries and less need for a trickle charger, get the 10 amp version. I am leaning into getting one to replace my old 10 amp charger. Review: Great compact charger when car needs a quick battery charge - Really impressed with this charger. It’s super easy to use—just hook it up and it pretty much does everything on its own. I like that it works with both 6V and 12V batteries and even different types like AGM and lithium, so it’s pretty versatile. It’s also compact but still powerful, and I’ve used it to bring a weak battery back to life without any issues. The automatic maintenance mode is a nice touch too since you can leave it connected without worrying about overcharging . Overall, solid build, reliable performance, and great for keeping your car or motorcycle battery in good shape. ## Features - MEET THE GENIUS5 — Similar to our G3500, just better.

If you have two cars, you can buy two of AXTRA battery charger for one of the Noco 5 amp charger. Highly recommend AXTRA battery charger: www.amazon.com/AXTRA-Fully-Automatic-Maintainer-Motorcycle-Tractors/dp/B08T7V4VQC I am an auto mechanic for 33 years. I have been testing these two chargers for about 8 months so far. AXTRA battery charger has 3.6 amp and 0.9 amp for small, medium, large size cars and trucks. NOCO has 5 amp only. AXTRA is more adequate to trickle charge motorcycle, lawn mower and ATV. **Q: Should i buy two of axtra battery charger or one unit of noco genius 5 charger?** A: Well I'm in a unique position as I have BOTH chargers. The axtra charger works fine if you connect it and charge while watching it so to speak. The noco charger works flawless all the time. I have them both hooked to xtreme charger switching units right now. The noco charges fine when it switches to the next vehicle to charge on the switcher. The axtra works a few times then stops charging till you power cycle it. Someone mentioned in another answer than the noco only charges at max amps. This is a wrong. The noco trickle charges just like the axtra does when the battery is fully charged. Its annoying that I have to now purchase another noco charger for the 2nd switching setup since the axtra charger cant do the job so I'm out 30 something dollars on the axtra when I should of just bought two noco 5 chargers to start with. Live and learn. Sometimes a "deal" price wise isn't such a deal after all. So yes I would recommend one noco genius 5 charger over 2 or more axtra chargers :) **Q: How’s noco 5-amp battery charger compares to axtra car battery charger maintainer?** A: We believe the NOCO GENIUS5 is better. The new GENIUS Series - including the GENIUS5 - incorporates full-throttle technology that holds the maximum charge current throughout the bulk charge cycle. It uses temperature compensation via an external temperature sensor to alter the charging voltage based on the ambient environment, which eliminates overcharging in hot climates and undercharging in cold environments. It charges 6-volt and 12-volt batteries, including lithium-ion. It can be used for a wide variety of functions (recharging from any depth of discharge, maintenance, desulfation, etc.). **Q: Can I use this to maintain the charge in my car and leave it unattended for months during winter storage?** A: Noco Genius 5 amp battery charger will charge faster than AXTRA 3.6 amp. If you have two cars, you can buy two of AXTRA battery charger for one of the Noco 5 amp charger.

A full charge on a depleted battery may take 24 hrs or so but the lower rating allows me to use it with a 100 ft heavy gauge extension chord without worries. I would not want a smaller unit and a larger draw unit would make me worry about using an extension chord. Great and reliable unit. ## Frequently Bought Together - NOCO GENIUS5: 5A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries - NOCO GC008 X-Connect M10 XL Eyelet Terminal Accessory Genius Smart Battery Chargers - NOCO GC004 X-Connect 10-Foot Extension Cable Accessory Genius Smart Battery Chargers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/168237421-noco-genius5-5a-6v-12v-smart-battery-charger-automatic-maintainer](https://www.desertcart.it/products/168237421-noco-genius5-5a-6v-12v-smart-battery-charger-automatic-maintainer) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
