How long will a power station run a freezer?
A 1,000Wh power station runs a freezer on its own for about 9.5 to 23 hours, and a 2,000Wh one for about 19 to 46 hours. Starting it is the harder part: generator makers' charts allow up to about 2,600 watts for the moment it starts, and 16 of the 25 power stations we compare cover that, with 3 more worth checking against your own freezer's label.

Runtime: capacity × 90% usable × 85% inverter efficiency ÷ (the appliance's average draw + about 10W the station uses itself), a range from the low and high average draw. "Runs it?" checks the station's output against 400–750W running and its surge rating against 2,250–2,600W to start, the cautious figures from generator makers' and DTE Energy's charts. Many modern appliances start with less, so "Check" means read your appliance's label (amps × 120 = watts). Plan on the low end of every runtime.
Where the figures come from
Generator charts treat a freezer like a refrigerator (DTE Energy lists them together at 750 running watts, starting factor 3). The day-long average is lower: Energy Star certified chest freezers start at about 200 kWh a year (23W), and upright freezers built to the federal maximum reach about 620 kWh (71W). A full freezer keeps food frozen for about 48 hours with the door shut, so it may not need power at all in a short outage: see food safety in a power outage.

How long will a 1,000Wh power station run a freezer?
About 9.5 to 23 hours, running nothing else, on the figures behind this page. Plan on the low end.
What size power station do I need for a freezer?
For 12 hours, about 895Wh, or 1,271Wh for an older or larger one, with at least 750W of output and a surge rating of about 2,600W to start it.
Can a power station run a freezer in an outage?
Yes, if its output covers about 750W and its surge rating covers about 2,600W. A power station is safe to run indoors, unlike a generator.
