A Reddit user reported that an EcoFlow Delta 3 Classic powering a garage freezer fell from 60% to 30% overnight—even with the freezer switched off from midnight to 7 a.m.—and said the inverter, left on, appeared to account for about 300 watt-hours of loss.
At that reported rate, the article calculates, the loss would amount to about 9 kilowatt-hours a month, or roughly 110 kilowatt-hours a year.
The discussion's main proposed fix was to schedule the station's AC output to turn off when the freezer can safely coast. Commenters also suggested disabling X-Boost to reduce potential standby overhead.
