Scenario
What size power station keeps a fridge running through a 24-hour outage?
Our best fit is the PECRON E2400LFP, at about 33 h calculated. The plan needs 1,252 Wh at the outlet over 24 hours and about 1,000 W at start-up, from maker specs and cited appliance figures checked .

Goal: 24 h. Hours use maker inverter efficiency where published, otherwise the 0.85 estimate, and leave out idle draw the maker doesn't publish. Stations shown out of stock or with availability not shown are skipped. How we pick.

Devices and assumptions
| Device | Qty | Hours a day | Running | Starting | Source |
|---|---|---|---|---|---|
| Refrigerator (full-size) | 1 | On the whole time | 275 W | 1,000 W | ENERGY STAR data + Champion chart · cycles about 19% of the time calculated |
Together: 275 W running, about 1,000 W while the largest motor starts, and 1,252 Wh a day. Over the 24-hour goal that is 1,252 Wh at the outlet calculated.
- Full-size fridge energy is the median ENERGY STAR annual figure spread evenly over the day.
- Starting watts are the midpoint of the Champion Power Equipment chart range.
- The fridge stays plugged in the whole outage; opening the door less helps.

What would change this answer
- Your own device watts: the label on the device beats any typical figure. Enter it in the calculator.
- Inverter idle draw: most makers don't publish it, so hours here leave it out. Small loads feel this most.
- Cold: below a maker's temperature range a station may stop discharging or charging.
Our take
A full-size fridge is mostly a starting-watts problem, not a battery-size problem: the compressor's start is several times its running draw, so check surge first. After that, the daily energy of a modern ENERGY STAR fridge is modest, which is why mid-size stations cover a day. Older fridges can use far more, so read the yearly kWh on your fridge's yellow EnergyGuide label and enter your own watts in the calculator.
