How long will a power station run a chest freezer?
A new ENERGY STAR chest freezer: about 37.4 h on a 1 kWh station. The average US freezer in use: about 14 h.
| Station | Capacity | ENERGY STAR, 24.3 W | US average, 65 W |
|---|---|---|---|
| BLUETTI Elite 30 V2 | 288 Wh | 7.3 h | 3.3 h |
| Jackery Explorer 600 v2 | 640 Wh | 22.4 h | 8.4 h |
| Anker SOLIX C1000 Gen 2 | 1,024 Wh | 35.8 h | 13.4 h |
| Jackery Explorer 1000 v2 | 1,070 Wh | 37.4 h | 14 h |
| Jackery Explorer 2000 v2 | 2,042 Wh | 3 days | 26.7 h |
| EcoFlow DELTA 3 Max Plus | 2,048 Wh | 3 days | 26.8 h |
| Anker SOLIX S5000 | 5,024 Wh | 7.3 days | 2.7 days |
Like a fridge, a freezer cycles on and off, so use its yearly kWh. An ENERGY STAR 10.1 cu ft chest freezer uses 213 kWh a year (ENERGY STAR), about 24.3 W averaged. The average separate freezer in US homes used 570 kWh (EIA), about 65 W. Divide your label’s kWh a year by 8.76 for watts.
A full freezer holds a safe temperature for about 48 hours with the door shut, a half-full one about 24 (FoodSafety.gov). Running it a few hours at a time stretches a small station a long way.
The compressor needs a short burst of power to start. Check the surge rating on each station page.
Quick answers
How long will a 2,000 Wh power station run a chest freezer?
About 3 days for an ENERGY STAR 10.1 cu ft model on the Jackery 2000 v2, or 26.7 h for the average US freezer in use.
Does a chest freezer use less power than a fridge?
Often, but not always. EIA’s averages are 570 kWh a year for freezers and 617 kWh for most-used fridges; a new ENERGY STAR chest freezer can use far less.
