Chest freezer runtime · EcoFlow DELTA 2 Max
How Long Will an EcoFlow DELTA 2 Max Run a Chest Freezer?
About 26.7 h for an average US freezer in use (570 kWh a year, 65.1 W), by our math: 2,048 Wh × 0.85 ÷ 65.1 W. Across the cases below: 26.7 h to 3 days.

Freezer hours on the DELTA 2 Max
| Case | Watts | On the DELTA 2 Max |
|---|---|---|
| ENERGY STAR 10.1 cu ft freezer (213 kWh a year) (ENERGY STAR) | 24.3 W | 3 days |
| Average US freezer in use (570 kWh a year) (EIA) | 65.1 W | 26.7 h |
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
These are yearly averages. A full freezer stays safe about 48 hours with the door shut, so running it in shifts stretches the battery (FoodSafety.gov).
Can the DELTA 2 Max start it?
Compressors can need two to four times their rated power to start (BLUETTI manual). We use the same 900 W planning figure as for a fridge. The DELTA 2 Max’s surge of 4,800 W covers that.
Keeping it going with solar
A day with an average US freezer in use (570 kWh a year) uses about 1,562 Wh, about 1,838 Wh from the battery. At the DELTA 2 Max’s 1,000 W solar input and our 75% assumption, that takes about 2.5 hours of strong sun to put back; a full charge from empty takes about 2.7 hours. See solar recharge time.
