Best overall: EcoFlow DELTA 3 Plus. Best value: BLUETTI AC180. Best for long outages: Jackery Explorer 2000 v2. Whole-home: Anker SOLIX F3800.
A portable power station is a big rechargeable battery with wall outlets. In an outage, it can keep your fridge cold and your food safe without the fumes and noise of a gas generator, so it can be used indoors.
For most homes, the EcoFlow DELTA 3 Plus: about 1 kWh, fast backup switchover and room to add batteries. On a budget, the BLUETTI AC180. If outages last overnight, step up to a 2 kWh unit like the Jackery 2000 v2; for a fridge and freezer over several days, the Anker SOLIX F3800.

How Long Can a Power Station Run a Fridge?
| Station size | Rough fridge runtime* | Good for |
|---|---|---|
| About 1 kWh | Often around 8 to 20 hours | Short outages, one fridge |
| About 2 kWh | Often around 16 to 40 hours | Overnight, fridge plus small loads |
| 3 kWh and up | Often a day or more | Fridge plus chest freezer, multi-day |
*Rough estimates for a modern, efficient fridge. Real runtime depends on the fridge, room temperature and how often the door opens; check your fridge’s energy label.
Keep a fridge thermometer inside so you know food stays at 40°F or below; see the best fridge and freezer thermometers with alarms.
Outage Tips to Make the Battery Last
Keep doors shut
Every opening lets cold out and makes the fridge run longer.
Cycle it
Run the fridge for a few hours, then unplug for a while if the inside stays cold.
Skip heaters
Avoid kettles and space heaters on the same battery; they drain it fast.
