How Many Watts Does a Refrigerator Use?

Quick answer: A modern full-size refrigerator uses about 100-200 watts while the compressor runs, surges to 900-1,200 watts at compressor start, and averages 30-50W over a day thanks to cycling. For backup sizing, plan around 150W running, 1,200W surge, and a ~35% duty cycle.

Refrigerators are the most common reason to buy backup power - a fridge holds $200-400 of food, and the USDA says food is unsafe after 4 hours above 40°F with the door closed. The good news: fridges are cheap to back up. At a 35% duty cycle, one uses only ~62Wh per hour after inverter losses. Keep the door shut and even a 1kWh station protects your food most of a day. The number that disqualifies small inverters is the compressor start surge - clear 1,200W and you're safe.

How long real power stations run a refrigerator

Computed from each unit's rated capacity at 85% inverter efficiency and a 35% duty cycle (150W running, 1,200W start). Units that can't clear the start surge are excluded.

Frequently asked questions

How long will a 1,000Wh power station run a refrigerator?

About 14 hours at a typical 35% duty cycle (fridge cycling normally, door closed). A 2kWh unit runs ~28 hours; a 4kWh unit runs 2+ days.

How long does food last in an outage without power?

USDA guidance: 4 hours in a closed refrigerator, 24-48 hours in a closed full freezer. Backup power removes the deadline entirely for ~62Wh per hour.

Can a small 300Wh power bank run a fridge?

Usually not - most sub-500Wh units have inverters under 600W that can't absorb the 1,000W+ compressor start. Check surge rating, not just capacity.
