In 24 hours at full output, the AS-CSJ72XK-2WT-OL pulls about 1.1 gallons of water from the air and uses about 2.2 kWh. That day costs $0.40 in the United States.
About 48 such days make up the EPA’s yearly estimate of 105 kWh. If yours runs at full output more often, every extra day adds $0.40.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the AS-CSJ72XK-2WT-OL pulls out less than 9 pints a day.
Those 1.1 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the AS-CSJ72XK-2WT-OL has.
