By situation Refrigerator
How many watts does a refrigerator use?
A typical refrigerator runs on about 280 watts and needs about 1,000 watts for a moment to start its compressor, the middle of Champion's 150 to 400 running and 800 to 1,200 starting ranges. Across our 8 sources it ranges from 132 to 750 running and 800 to 2,250 starting watts, so check your fridge's label.
With 20 percent headroom, a typical refrigerator alone needs 400 running and 1,200 starting watts: a small inverter generator or a power station covers it.
01 By type
Refrigerator watts by type
Most full-size refrigerators run on 150 to 400 watts, a mini fridge on 50 to 100 and a freezer on 100 to 500 (Champion). Typical figures first, the source's range in brackets.
| Type | Running W | Starting W | Source |
|---|---|---|---|
| Refrigerator, typical (any full-size type) | 280 (150 to 400) | 1,000 (800 to 1,200) | Champion wattage chart |
| Top freezer, no icemaker | 170 to 220 | not listed | EWEB appliance table |
| Side by side, with icemaker | 210 to 250 | not listed | EWEB appliance table |
| French door | no separate figure | no separate figure | None of our sources lists it apart; use the typical row |
| Mini fridge | 80 (50 to 100) | 500 (400 to 600) | Champion wattage chart |
| Freezer | 300 (100 to 500) | 750 (500 to 1,000) | Champion wattage chart ("Freezer") |
| Deep freezer | 500 | 1,000 | Briggs and Stratton worksheet (500 running plus 500 additional to start) |
| Compact chest freezer (Energy Star) | 160 to 200 | not listed | EWEB appliance table |
| RV refrigerator | 380 (150 to 600) | 700 (400 to 1,000) | Champion wattage chart |
The EWEB figures come from an energy-use table that gives no starting surge. Our sources list watts, not kilowatt-hours a day, so we do not give a daily kWh figure. Typical; check your appliance's label.
Every refrigerator figure in our sources
The sources disagree by more than you might expect, mostly on the starting surge. Briggs and Stratton lists only the extra watts to start, so we add them to running and mark the total "computed"; DTE Energy gives a multiplier.
| Source | Item as listed | Running W | Starting |
|---|---|---|---|
| Champion wattage chart | Refrigerator | 150 to 400 | 800 to 1,200 W starting |
| Honda wattage guide | Refrigerator or Freezer (Energy Star) | 132 to 192 | 1,200 W starting |
| Honda power management guide | Refrigerator (power management example) | 200 | 1,600 W starting |
| Briggs and Stratton worksheet | Refrigerator/Freezer | 550 | plus 1,350 W additional to start (1,900 W total, computed) |
| Westinghouse manual | Refrigerator or Freezer | 700 | 2,200 W starting |
| Champion flyer | Refrigerator | 400 | 2,200 W starting |
| DTE Energy worksheet | Refrigerator/Freezer | 750 | starting factor 3 (2,250 W total, computed) |
| EWEB appliance table | Refrigerator, top-mount freezer, no icemaker (energy-use table, no surge figure) | 170 to 220 | no starting figure given |
| EWEB appliance table | Refrigerator, side-mount freezer, with icemaker (energy-use table, no surge figure) | 210 to 250 | no starting figure given |

02 Generator size
What size generator runs a refrigerator?
A small one. A typical refrigerator alone needs 400 running and 1,200 starting watts with 20 percent headroom, and a 2,000 W class inverter covers it with room for lights and chargers.
- Refrigerator alone: 280 W running plus its 720 W surge is 1,000 W, so 400 running and 1,200 starting watts with headroom.
- Refrigerator and a freezer: 700 running and 1,600 starting watts. Only the bigger surge counts, because Briggs and Stratton says only one item usually starts or cycles at a time.
- A fridge at the high end: Westinghouse lists a refrigerator or freezer at 700 running and 2,200 starting watts. That needs 900 running and 2,700 starting watts, more than a 2,200 W inverter's peak, so a 3,000 W class generator is the safer size.
Worked example: food and phones
| Item and source | How many | Running W | Starting W (one) |
|---|---|---|---|
| Refrigerator Champion wattage chart | 1 | 280 | 1,000 |
| Chest freezer Champion wattage chart | 1 | 300 | 750 |
| LED bulb Champion wattage chart | 6 | 120 | 20 |
| Internet router/modem Champion wattage chart | 1 | 20 | 20 |
| Phone charger Champion wattage chart | 3 | 180 | 60 |
| Running total | 12 | 900 | + 720 (refrigerator) |
900 W running plus the refrigerator’s 720 W surge is 1,620 W. With 20 percent headroom that is 1,080 and 1,944 W, rounded up to 1,100 running and 2,000 starting watts. The small inverters below cover it. Adding a microwave, a furnace blower and a sump pump is our outage essentials list, which needs a 5,000 W class generator.
Run it outside only, at least 20 feet from the house with the exhaust pointed away, never in a garage even with the door open, and put battery-backed CO alarms on every level (CPSC).
03 Power station
What size power station runs a refrigerator?
One rated for at least 400 watts with a surge rating of at least 1,200, the same numbers as a generator. A 1 to 2 kWh station covers a typical refrigerator.
Jackery says the load should be less than the power station's rated wattage, and to check both its rated and its surge output. Consumer Reports calls power stations the only type of generator that can be used indoors safely, with no fumes and virtually no noise. The catch, also from Consumer Reports: when one goes dead and you cannot recharge it from solar, you cannot just add another gallon of gas.
How long a power station runs a refrigerator
Jackery's formula: runtime in hours = capacity in watt-hours × 0.85 ÷ the device's watts. The 0.85 covers power lost in conversion. At a nonstop 280 W, a 1,070 Wh station gives about 3.2 hours.
| Power station | Capacity | Refrigerator (280 W) | Fridge and freezer (580 W) |
|---|---|---|---|
| Jackery Explorer 1000 v2 | 1,070 Wh | 3.2 h | 1.6 h |
| Anker SOLIX C1000 | 1,056 Wh | 3.2 h | 1.5 h |
| Jackery Explorer 2000 v2 | 2,042 Wh | 6.2 h | 3.0 h |
| EcoFlow DELTA 3 Ultra | 3,072 Wh | 9.3 h | 4.5 h |
The formula treats the refrigerator as drawing its running watts every minute. For comparison, Consumer Reports' 2019 tests ran a side-by-side refrigerator for 13 to 44 hours on the power stations it tested. Jackery calls its own runtime figures for reference only, so treat these as rough planning numbers.

05 Questions
Refrigerator watts questions
How many watts does a refrigerator use?
About 280 watts while it runs, the middle of Champion’s 150 to 400 W range. Across our sources the running figure ranges from 132 to 750 W, so your fridge’s label is the real number.
How many watts does a refrigerator need to start?
About 1,000 watts for the first moment, the middle of Champion’s 800 to 1,200 W range. Other sources run higher: Westinghouse lists 2,200 W and DTE Energy’s factor gives 2,250 W.
How many watts does a mini fridge use?
About 80 watts running and 500 starting, the middle of Champion’s 50 to 100 W and 400 to 600 W ranges.
How many watts does a freezer use?
About 300 watts running and 750 starting for a freezer, from Champion’s 100 to 500 W and 500 to 1,000 W ranges. Briggs and Stratton lists a deep freezer at 500 running watts plus 500 to start, and EWEB a compact Energy Star chest freezer at 160 to 200 W.
What size generator do I need to run a refrigerator?
For a typical refrigerator alone, 400 running and 1,200 starting watts with 20 percent headroom, so a small inverter or a power station covers it. With a chest freezer, lights, the router and phone chargers it needs 1,100 running and 2,000 starting watts, which a 2,000 W class inverter covers.
Will a 2,000 watt generator run a refrigerator?
Yes, for a typical refrigerator (400 running and 1,200 starting watts). If your fridge’s label shows a high starting figure, like Westinghouse’s 700 running and 2,200 starting watts, it needs 900 running and 2,700 starting watts, which is more than a 2,200 W inverter’s peak.
Will a 3,500 watt generator run a refrigerator?
Yes, with room for more. A 3,500 W generator also runs a microwave, a TV, lights, the router, chargers and a laptop alongside the fridge in our 3,500 W example.
Can one generator run a refrigerator and a freezer?
Yes. A typical refrigerator and a freezer together need 700 running and 1,600 starting watts. Only the bigger surge counts, because the two compressors rarely start at the same moment; Briggs and Stratton says only one item usually starts or cycles at a time.
How long will a power station run a refrigerator?
Use Jackery’s formula: watt-hours times 0.85, divided by the watts. A 1,070 Wh station running a 280 W refrigerator nonstop gives about 3.2 hours. Consumer Reports’ 2019 tests ran a side-by-side refrigerator for 13 to 44 hours on the power stations it tested. Treat any figure as a rough guide.
Can I run the refrigerator through an extension cord from the generator?
Yes, with the right cord: CPSC says to use a heavy-duty outdoor cord rated for more watts than everything plugged into it, with all three prongs. Keep the generator at least 20 feet from the house; Westinghouse warns that cords run directly into the home raise the risk of carbon monoxide coming in through the openings.
