A very NICE product indeed. I took out my car battery and after cleaning it a bit I charged it for a couple of hours. I checked the process between random intervals to see the battery voltage. I only hear the fan turn on twice at the very beginning and it was also pretty quiet. The device is abuse and abuse proof, so this should be the joy of our lives if we don't all start driving 100% EV. until 2020 laugh. I'm giving two thumbs up as the shipping was SUPER fast with delivery in less than 24 hours no kidding. :) The battery was charged and I've been driving ever since. This will teach me NOT to run the AC at full speed with the engine off and the neon lights on haha. The only downside is confusion with the CA extension at the end of the product as the part is advertised as SC-600-CA but ships as SC-600 without a CA. I know read the disclaimer what I did. I love Schumacher products and have used them on AGV and AGM batteries. So buy with confidence, I did :) AMAZON Schumacher SC-600A-CA SpeedCharge 6A High Frequency Charger
