It can stay in the car near the battery pack ready for use. **Q: The description for the noco genius2duk says it has a battery repair & conditioner mode, yet the comparison table says it doesn't - which is it ?** A: The GENIUS2D desulfates during both the 12V and 6V charging modes. It is one of the first few steps in the charging process, if the charger detects sulfation in the battery it will automatically start desulfating during the charge, there is nothing that you need to do to activate it. The 12V Repair Mode that the larger models have is an additional mode dedicated to recovering heavily sulfated, stratified, old, damaged, and/or idle 12V batteries. **Q: Is any using adhoc rather Onboard?** A: Most modern cars come with modular battery’s and are covered. The idea of these units is to add a battery charger that doesn’t need to be disconnected every time. You’d just plug the charger into an extension lead which you’d keep dry under the bonnet. **Q: I want to connect it to a power inverter in my car's boot. Will it draw much power just to trickle charge my additional battery?** A: The NOCO Genius chargers have not been tested to be powered by inverters or generators. In theory, it will work as long as the power requirements of the charger are met. I have listed the power requirements below for the charger, including the max amperage draw of the charger. Working VAC: 120-240 VAC, 50-60 Hz Max Draw: 28W 0.12A @ 240V AC. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality and affordable *by A***Y on 9 November 2025* Excellent charger well made very durable and easy to use ### ⭐⭐⭐⭐⭐ Perfect *by L***R on 9 December 2025* Perfect mounted next to the battery in my van, just the job ### ⭐⭐⭐⭐⭐ It works great! *by S***S on 19 September 2023* I had to leave my car for 6 months while I was abroad. I decided to connect this to the battery and plug it in and trust that it worked and didn't cook the battery. I was apprehensive and figured that if I let the battery to run down, it would need replacing and if the charger cooked the battery I'd need a new battery anyway. I was able to monitor the voltage via an app on my car and saw it vary between 14.5v and 12.0v It looked okay and it was with some trepidation that I returned and went to the car. I disconnected the charger and the car started first time and the battery was fully charged! Perfect. Since then, the car has run perfectly, no damage to the battery and all is well. I'm so grateful for this little intelligent charger! Wow! Love it. ## Frequently Bought Together - NOCO GENIUS2D: 2A 12V Smart Onboard Battery Charger - Direct-Mount Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid Batteries - NOCO GC004 X-Connect 3-Meter Extension Cable Accessory for NOCO Genius Smart Battery Chargers - NOCO GC002 X-Connect M6 Eyelet Terminal Accessory for 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.ma/products/219844874-genius2d-2a-12v-smart-onboard-battery-charger-direct-mount-automatic](https://www.desertcart.ma/products/219844874-genius2d-2a-12v-smart-onboard-battery-charger-direct-mount-automatic) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-04-27*
