How Long Will an EcoFlow RIVER 3 Plus Run a Chest Freezer?
About 3.7 h for an average US freezer in use (570 kWh a year, 65.1 W), by our math: 286 Wh × 0.85 ÷ 65.1 W. Across the cases below: 3.7 h to 10 h.

Freezer hours on the RIVER 3 Plus
| Case | Watts | On the RIVER 3 Plus |
|---|---|---|
| ENERGY STAR 10.1 cu ft freezer (213 kWh a year) (ENERGY STAR) | 24.3 W | 10 h |
| Average US freezer in use (570 kWh a year) (EIA) | 65.1 W | 3.7 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 RIVER 3 Plus 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 RIVER 3 Plus’s surge of 1,200 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 RIVER 3 Plus’s 220 W solar input and our 75% assumption, that is more than the 286 Wh battery holds, so the battery alone won’t cover it; a full charge from empty takes about 1.7 hours of strong sun.
