We bought this unit because of its low amp draw and reported reliability, to use with a small generator in case of a power outage (good timing with a hurricane now bearing down on us). We’ve been using the unit on house current to supplement the central AC in the super hot weather. The “auto” and “eco” features have brilliantly limited the unit run time and speed. We never think about it. The unit simply keeps our bedroom cool and dry. Also a great value.
