How many watts does a coffee maker use?
Updated
Running watts
1,000 W
Starting watts
1,000 W
Energy per day
500 Wh
A coffee maker typically draws about 1,000 watts while running. At about 0.5 h of use a day, that is roughly 500 Wh 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 coffee maker?
Plan for at least 1,200 W: 1,000 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 coffee maker? |
|---|---|
| 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 coffee maker?
Running continuously at 1,000 W, assuming 85% of the battery is usable. The station's AC output must also handle the 1,000 W start-up surge.
| Battery capacity | Runtime |
|---|---|
| 1,000 Wh | about 51 min |
| 2,000 Wh | about 2 h |
| 3,600 Wh | about 3 h |
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 coffee maker?
At least 1,200 W: 1,000 W to cover the start-up surge, plus a 20% safety margin.
Can a 2,000 watt generator run a coffee maker?
Yes. 2,000 W covers its 1,000 W starting surge with room to spare.
Can a 3,500 watt generator run a coffee maker?
Yes. 3,500 W covers its 1,000 W starting surge with room to spare.
How long will a 1,000 Wh power station run a coffee maker?
About 51 min, assuming 85% usable capacity, as long as the station's AC output is rated for 1,000 W of surge.
Never run a generator indoors or in a garage: see the CPSC safety guide.
