Power stations › Scenarios › Fridge + freezer through an outage

What size power station do I need to run a refrigerator and a freezer?

Protecting both the fridge and a full chest freezer is the serious food-security scenario. Two compressors mean two surges and roughly double the energy, so this pushes into the larger station sizes — or a smaller one topped up by solar.

The load

POWER PLATE2 LOADS · 12 H RUNTIME
Continuous draw
550 W
Startup surge
1,750 W
Energy for 12 h
7,765 Wh
Buy at least
8,650 Wh
Look for ≥8,650Wh capacity, ~550W continuous / 1,750W surge or better.

Field note: A full chest freezer holds temperature for around 48 hours if you keep it closed, so in a pinch you can power the fridge continuously and give the freezer battery time in blocks. Solar recharge is what makes covering both loads through a multi-day outage realistic without buying the biggest station on the shelf.

Right size: Expandable home backup (≈6,000Wh+) · 5,000W

Typical price $3,500-6,000+ · e.g. EcoFlow Delta Pro Ultra, Bluetti AC500 + B300S (stackable)

Backing up whole circuits through a transfer switch; add battery modules for days of autonomy, especially with solar. A home-backup system, not a grab-and-go unit. For 240V loads or true whole-home coverage, compare against a standby generator.

Runs this load ~8.3 h on a full charge.

This is a heavy or long load for battery power — plan on solar recharge or compare a fuel generator.

Capacity includes inverter loss (~15%) and a usable-charge margin, so the station isn't run flat. A solar panel or vehicle charge extends runtime past this number.

This load is heavier or longer than portable stations cover well. Add solar recharge, shorten the runtime, or look at a fuel generator for sustained high-wattage loads.
