A clothes iron uses about 1,000-1,800 watts while heating, typically around 1,200 W. Its thermostat cycles the element on and off, so average draw is lower, but your power source must handle the full wattage.

Watts by model and setting
Most clothes iron models draw between 1,000 and 1,800 W while running; a typical one draws about 1,200 W. 1,200 W x 15 min/day with the thermostat cycling the element about half the time.
- Rated wattage: steam irons and steam stations are often 1,500-1,800 W
- Temperature setting: hotter fabric settings keep the element on longer
- Steam use increases heating time
- Auto-off features cut wasted energy
Running a clothes iron on a generator or power station
- Generator: at least 1,200 running watts. A generator rated 2,000 W or more covers it with room to spare.
- Power station: continuous output of at least 1,200 W. Pure sine wave output is the safe choice for motors and electronics.
| Power station capacity | Estimated runtime |
|---|---|
| 500 Wh | 0.7 h |
| 1,000 Wh | 1.4 h |
| 2,000 Wh | 2.8 h |
| 3,000 Wh | 4.2 h |
Based on 600 W average draw (running watts × duty cycle) and 85% usable capacity.
- Needs a power station or generator that can supply the full rated wattage; the thermostat switches the element fully on
- Ironing is a low priority during outages
- Run any generator outdoors, well away from doors, windows and vents; never in a garage or basement, because of carbon monoxide.

Questions people ask
Can I use an iron on a portable power station?
Only if its continuous output exceeds the iron's rating, usually 1,200-1,800 W; it will drain the battery quickly.
How much electricity does ironing use?
About 0.15-0.3 kWh for 15-20 minutes, since the element cycles on and off.
