How many watts does a mini fridge use?
Updated
Running watts
100 W
Starting watts
300 W
Energy per day
700 Wh
A mini fridge typically draws about 100 watts while running and up to 300 watts for a second or two when the motor starts. It cycles on and off all day, which works out to roughly 0.7 kWh per day. These are typical values from generator wattage charts: the label on your own appliance (or its EnergyGuide sticker) gives the exact figure.
What size generator do I need for a mini fridge?
Plan for at least 360 W: 300 W to get through the start-up surge, plus a 20% margin so the generator never runs flat out. Of the common sizes, a 2,000 W generator is the smallest that fits.
| Generator | Can it run a mini fridge? |
|---|---|
| 2,000 W | Yes |
| 3,500 W | Yes |
| 5,000 W | Yes |
| 7,500 W | Yes |
| 10,000 W | Yes |
| 15,000 W | Yes |
How long will a power station run a mini fridge?
Based on its average draw over a day, assuming 85% of the battery is usable. The station's AC output must also handle the 300 W start-up surge.
| Battery capacity | Runtime |
|---|---|
| 1,000 Wh | about 29 h |
| 2,000 Wh | about 2.4 days |
| 3,600 Wh | about 4.4 days |
Running more than one appliance?
Starting surges don't add up the way running watts do. Pick everything you want to power to get your real number.

What size generator do I need to run a mini fridge?
At least 360 W: 300 W to cover the start-up surge, plus a 20% safety margin.
Can a 2,000 watt generator run a mini fridge?
Yes. 2,000 W covers its 300 W starting surge with room to spare.
Can a 3,500 watt generator run a mini fridge?
Yes. 3,500 W covers its 300 W starting surge with room to spare.
How long will a 1,000 Wh power station run a mini fridge?
About 29 h, assuming 85% usable capacity, as long as the station's AC output is rated for 300 W of surge.
Never run a generator indoors or in a garage: see the CPSC safety guide.
