Customer Ratings & Reviews

The NOCO Genius1 is a compact, reliable little charger that does exactly what it promises. It’s perfect for maintaining smaller batteries like those in motorcycles, lawn equipment, or seasonal vehicles, and it can safely be left connected without worrying about overcharging. I really like the safety features (spark-proof, reverse polarity protection) and the fact that it can even bring back low-voltage batteries using its repair/force mode. That said, at only 1 amp it charges slowly—great for maintaining, but if you’re trying to revive a large car or truck battery, expect it to take quite a while. The LED indicators are clear enough, but a digital display with more detailed feedback would have been nice.

I have a lot of cars and use these constantly. This is my 11th one and I have kept them plugged in 24/7 for years w/o a hitch. The best

Works great, came in handy. This model you can unscrew the clips and use the screws directly to your battery making quick disconnect and connection super easy
