How many watts does an electric stove use
While it's running, an electric stove draws 1,200 to 2,400 W, and it has no surge at start. A portable rated 3,000 W is the smallest one that can run it.
Watts for running and starting
| Load | Running | Starting |
|---|---|---|
| Electric range, one burner | 1,200 to 2,400 W | no surge |
The Champion wattage chart, 04-17-26, is the source. Check the nameplate on your own electric stove for its exact rating in watts or amps. For amps, multiply by 120 V. Use 240 V only when the load runs on a two-pole breaker; a well pump is one example.
The smallest generator able to start it
To carry 2,400 W, a generator must not exceed 80% of its rating. For both conditions, the smallest common portable is 3,000 W. Other loads add their running watts to the same generator.
An electric range, one burner, with other loads
| Electric range, one burner plus | Running | Peak at a start | Smallest portable |
|---|---|---|---|
| lights, TV and the router | 2,970 W | 2,970 W | 4,000 W |
| a freezer and lights | 3,050 W | 3,550 W | 4,000 W |
| a 1/2 hp sump pump and lights | 3,600 W | 4,700 W | 5,000 W |
| a microwave | 3,600 W | 3,600 W | 5,000 W |
| a 1 hp well pump | 4,400 W | 6,400 W | 6,500 W |
| a window AC, 10,000 BTU | 3,600 W | 4,800 W | 5,000 W |
Running watts add up, and the biggest motor start is the only surge that lands on top. Starting output on a portable runs about 25% above its running rating. The appliance wattage chart lists every load.
