Review: Not USA made but USA designed - This thing is working great. Easy setup. I used the mounting strap for a permanant mount under the hood of my 2022 Ford E350 RV. I bought this because of the good reviews and that it was said to be a USA made product -- I managed install and hook up in about 30 minutes. I sat down and went through the extra material, real happy with myself over my talented ability to install without instructions (ha, ha). The product is well-made, expensive, sure, but a really nice unit. BUT - It is NOT USA MADE. According to the material that came with this charger, it is made in Vietnam, not in the US, as someone claimed. It is, however, DESIGNED in the USA, but made, or assembled in VIETNAM, or other cheap labor countries, not sure, but mine came from V ... I originally thought I was buying a 100% USA made product, which justified, to my mind, the high price. Will I return it? No, it is doing the job, and is certainly a quality item. I just like to support USA manufacturing and American jobs whenever I can -- something hard to do these days. I buy Ford because it is still a USA owned company, even though half or more, of their cars are filled with components and parts from other countries. It is hard to see any other difference between other manufactures when we see auto plants, like Hyundai, and Toyota, opening assembly plants in the US. The lines get really blurred. Okay, enough -- just be aware -- it is not an American-made product, it is designed in America and assembled somewhere else. 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.

I have a 30+ yr old truck that we don't drive very much, so the battery is often discharged. Our old, large charger stopped working, so I bought this as a smaller option. The eye terminals can be attached to the battery/vehicle directly and left under the hood, then just plugged into the charger when you want to charge it back up. The 5A charge isn't super-speedy, but I knew that going in, so I use this to charge overnight and the battery is ready to go by the morning. If you need faster charging, look for a version of this product that offers more charging power. Once charging is complete, it will stay in maintenance mode and maintain the charge, so you can get it started way in advance and you'll still be good. It's very easy to use, with only one button to control selection of the battery type and/or charge mode. It's not complex, but always takes me a few attempts to find repair mode. Press and hold for 3 seconds to switch to a 6V battery. Press and hold for 5 seconds to switch on Force mode, which you'll need if the battery is really dead (under 1V) - that will attempt to charge even without sensing the battery is connected. To get to repair mode, you'll have to be connected to the battery, in standby, then press and hold for 5 sec, which I think starts both Force and Repair. This is small and light enough to store in your glove box, and can be tucked into a small corner of the engine compartment so you can close the hood while it charges. I like Noco products - they're well worth the price for high quality gear. ## 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.gr/products/168237421-noco-genius5-5a-6v-12v-smart-battery-charger-automatic-maintainer](https://www.desertcart.gr/products/168237421-noco-genius5-5a-6v-12v-smart-battery-charger-automatic-maintainer) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-03*
