I run a small Honda 1000 watt generator and the noise just disappears. It's extremely quiet, light and reliable. I've owned mine for over 2 yrs charging 30 cell planes and now Lipos. It weighs 28lbs and is a lot more convenient than dealing with wet cell batteries. People are always shocked at how quiet the unit is. I've never had a complaint at an electric funfly and you certainly won't hear it at a glow field. Plus it's nice to have when the power goes out at home.
