Good product and if need GREAT customer service *by on Reviewed in the United States July 2, 2026* If your even remotely considering buying this do it. My bf uses it for his car to prevent from buying so many batteries on his garage baby. I got it. Did exactly as it said and very good we had no issues. Until recently we noticed no lights were on the device. Well we were within warranty. But we all know how that goes. But! To my surprise it was extremely easy. The person I spoke with was very kind. They immediately sent a replacement after testing ours. So good product good customer service always good! And we have more than one the other hasn't skipped a beat. We will for sure be buying more products from this company! ### ⭐⭐⭐⭐⭐ Great little trickle charger. *by on Reviewed in the United States August 11, 2026* Charged a very low battery and has maintained the charge. Works great. ### ⭐⭐⭐⭐⭐ Very reliable *by on Reviewed in the United States August 2, 2026* This is now my second unit. The first has been running flawlessly, nonstop, for 4+ years, keeping the lithium replacement battery on one of my motorcycles topped up. I just upgraded to a lithium battery on one of my other motorcycles and immediately bought this unit. It charges quickly. It does not overcharge. The battery I bought this charger for the first time is still in service, which tells me this little charger is VERY good a maintaining batteries. As a motorcycle battery tender/maintainer, I don’t think you can beat it. I highly recommend. ## Frequently Bought Together - NOCO GENIUS2: 2A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries - SafeAMP Wire Harness Compatible with NOCO(R) GC008 X-Connect, M10 (3/8in) XL Eyelet Terminal Connector - NOCO GENIUS1: 1A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries --- ## 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.jp/products/168875225-noco-genius2-2a-6-12v-smart-battery-charger-trickle-charger](https://www.desertcart.jp/products/168875225-noco-genius2-2a-6-12v-smart-battery-charger-trickle-charger) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
