Does the job easily and it’s small and portable. Great value for money. Highly recommend this charger. Review: Really quite impressed - Bought this item due to its popularity, good reviews, and its cost. Was a bit of a stab in the dark. But, I really am impressed with its ease of use and performance. With regards to the charging lights, there's only 4 different light sequences which keep it nice and easy to understand. Keeps my battery charged full throughout the winter evenings. Plus, you can keep it connected the whole time and just leave it, as it keeps the battery at 100% without overcharging it. A nice, compact bit of kit. Was quite surprised with how small it is, but it packs quite a good punch. Another cool thing I like, is that you can remove the clamps from the wires, and then just directly screw the metal rings onto the battery and leave it on. So when you want to charge, just plug it into the plastic socket at the other end of the wire. Makes it so much simpler to use. Overall, really happy. Been recommending to all my biker friends. ## Features - MEET THE GENIUS1UK — Similar to our G750UK, just better. It's 35% smaller and delivers over 35% more power.

Will it charge a 100 AH battery ?** A: The GENIUS1 can charge a 100 amp-hour battery, but it will be an extended charge time if the battery is completely dead. For example, the GENIUS1 would take roughly 76-hours to recharge a dead battery. For comparison, the GENIUS2 would be 37-hours, the GENIUS5 would be 15-hours and the GENIUS10 would be 7-hours. **Q: Will it auto resume maintaining the battery after a power cut ?** A: It should do as I understand anytime it is used it should start up from the last setting each time, so when I go to set up the charger next time it will automatically go to the 12V set up I used the first time. **Q: Does anyone know if i have to disconnect the car battery leads first to use this charger? or can i literally pop the hood and connect it up?** A: You do not have to disconnect the battery from the car. **Q: Which model can you suggest for an audi tt, 3.2 l. the car is rarely used, but i want to keep the battery topped up** A: The basic model I have found to be totally satisfactory….I use it on my Mazda 2…it was recommended by the AA guy who came to start my car. Much better than my old charger. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Value for money and quality. *by J***. on 23 February 2026* Works extremely well. Does the job easily and it’s small and portable.

The item had arrived unsealed and with tears to the packaging so it seems as it had been returned as defective before being sent out to me. The replacement arrived the next day, properly sealed, and I set it up in my camper. It worked exactly as it should and is now keeping the starting battery topped up. ## Frequently Bought Together - NOCO GENIUS1: 1A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries - NOCO GC002 X-Connect M6 Eyelet Terminal Accessory for Genius Smart Battery Chargers - NOCO GC004 X-Connect 3-Meter Extension Cable Accessory for NOCO 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.sk/products/169905284-noco-genius1-1a-6v-12v-smart-battery-charger-automatic-maintainer](https://www.desertcart.sk/products/169905284-noco-genius1-1a-6v-12v-smart-battery-charger-automatic-maintainer) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-27*
