What to know

A chest freezer is the lightest cold appliance to carry through an outage. The class in the data uses 0.8 kWh a day, an average of 33.3 W, against 300 W while the compressor runs and about 750 W to start.

Two days take 1,600 Wh usable, about 1,882 Wh of rated capacity at 85% efficiency. 28 of the 54 stations are enough. The closest fit is the ALLPOWERS R2500 V2 (1,920 Wh), with 2.0 days. 5 cannot power it, 5 of them on the start.

A full freezer holds its cold for about 48 hours with the lid shut and no power at all. That gives you room to switch the station off for hours at a time and save the battery, as long as the lid stays closed.

An upright freezer uses more energy in the data, 1.2 kWh a day, and the question below works one out. To keep a refrigerator going as well, see the fridge and freezer setup.

Questions

What size power station do you need for a chest freezer in an outage?

This setup uses 800 Wh a day. Lasting 48 hours takes 1,600 Wh usable, about 1,882 Wh of rated capacity at 85% efficiency. It also needs 300 W of continuous output and a surge rating of 750 W for the start.

Which is the smallest power station that is enough?

The ALLPOWERS R2500 V2, at 1,920 Wh: 1,632 Wh usable gives 2.0 days of this routine. The ranking puts the smallest capacity first, then the lower price, then the lighter unit.

What about an upright freezer instead?

With an upright freezer in place of a chest freezer, the setup uses 1,200 Wh a day and needs 300 W running and 750 W to start. 16 of the 54 power stations are enough for two days without a recharge, against 28 for the setup above. The closest fit is the BLUETTI Elite 300 (3,014 Wh).
