What size power station for a chest freezer?
A typical certified chest freezer needs about 1,094.5 Wh for a day. Use the freezer’s own label if you have it. The chest-freezer estimate comes from only 9 certified models.
How we estimate this
Size it from the freezer’s own yearly kWh, not from a refrigerator’s. The public ENERGY STAR freezer list, read November 8, 2026, had only 9 certified non-compact chest freezers in this snapshot. Their annual use ran from 201 to 346 kWh, with a median of 218. That short list is not every chest freezer, and a larger or older unit can use more.
At the median, a 24-hour plan needs about 1,094.5 Wh. Estimated runtimes for in-stock matches, then any preorder that also covers the target:
- Jackery Explorer 1500 v2: about 33.7 hours. This is not a startup test.
- EcoFlow DELTA 3 Max: about 44.9 hours. This is not a startup test.
- Jackery Explorer 2000 v2: about 44.8 hours. This is not a startup test.
- EcoFlow DELTA 3 Max Plus: about 44.9 hours. This is not a startup test.
- EcoFlow DELTA 3 Plus + DELTA 3 Series Extra Battery: about 44.9 hours. This is not a startup test.
- EcoFlow DELTA 3 Ultra Plus: about 67.4 hours. This is not a startup test.
- Jackery HomePower 3000: about 67.4 hours. This is not a startup test.
- EcoFlow DELTA 3 Max Plus + Smart Extra Battery: about 89.8 hours. This is not a startup test.
- EcoFlow DELTA 3 Ultra Plus + DELTA 3 Max Plus Extra Battery: about 112.3 hours. This is not a startup test.
- Jackery Explorer 5000 Plus + Battery Pack 5000 Plus: about 221.0 hours. This is not a startup test.
A yellow EnergyGuide number replaces this estimate. The chest freezer backup page explains why a refrigerator’s kWh should not be pasted in. Closed-door hold time, about 48 hours for a full freezer on the USDA page, is food that is already frozen while the compressor is off. It is not the same as powering the freezer.
