    NOCO G3500 reviews

    Genius G3500 6V/12V 3.5A UltraSafe Smart Battery Charger is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Compact & Versatile My old (not so old) battery charger got rained on and was not waterproof so I needed a new one. I researched them and the NOCO kept popping up. Found one at a store and liked the size/look of it and really liked all of the good reviews and features. Just used it a few days ago and was not disappointed. Plug it in, attach the clips, push the button (there's only one) and it does what it says it will do. I love how small it is compared to my old charger. It will travel well and can get wet!
