How Long Will a Power Station Run a Chest Freezer?

Chest freezers are one of the easiest things to back up. An ENERGY STAR model averages about 29 W (0.7 kWh a day), so a 1,000 Wh power station runs one for about 29 hours and a 2,000 Wh station for about 2.4 days.

It still needs about 800 W for a moment when the compressor starts, which almost every power station over 500 W can handle.

Tips

A full freezer holds a safe temperature for about 48 hours with the door closed (24 hours if half full), per FoodSafety.gov. Running it a few hours a day is often enough.
Fill empty space with jugs of water. Frozen mass keeps the temperature stable between cycles.
Freezers in hot garages run longer. Expect more than our average figure in summer.
Upright freezers, especially frost-free ones, typically use more than chest freezers of the same size.

Questions

Can a 300 Wh power station run a chest freezer?

For several hours, if it can supply the startup surge. It’s better used to top up the cold a few hours at a time.

How long can a freezer go without power?

About 48 hours if full and 24 hours if half full, as long as the door stays closed (FoodSafety.gov).
