One 10 000 btu air conditioner may use 900 watts of electricity while another one uses 1 000 watts.
The total watts all depends on how energy efficient the manufacturer made the appliance.

Watts required for start up.
An average 5 000 btu air conditioner uses 500w of energy running at full capacity.

Your unit may have different ratings.
But because the compressor component needs a 50 to 100 additional surge of power to overcome inertia at start up a small window a c needs about 900 to 1200 watts briefly each time the compressor kicks in to start a cooling cycle.
Central a c fan only compressor off 750 watts largest window units 1440 watts medium window unit 900 watts.
With this you can estimate what size generator to run an air conditioner you will need.
The method however only gives you the starting or surge wattage.

That means the value you get shows the total watts required to start up an appliance.
What affects how many watts an air conditioner uses.
You just can t plug in additional loads that when added to the requirements of the air.
Average wattage once running.
Once the motor is running steadily the amperage drops and the wattage usually is around 1500.
Nearly most air conditioner models require about 2000 to 3000 watts to power on and run smoothly.
So how do you find out how many watts does a window ac use.
Even a 1 000 watt rated output generator will be adequate.
