Since watts are equal to volts times amps it is hard to say if a 2000 watt generator will be enough. If you know the amperage of the A/C then using the formula Amps = Watts/ Volts. 2000/110 = 18 amps. If the A/C draws more that 18 amps then a 2000 watt generator will not be large enough. To find the generator size you will need, just use the same formula and try different generator wattages until you find one that is about 5 amps higher than the A/C amps.

To answer this question the amperage of the air conditioner must be stated. The amperage when found is then multiplied by the voltage output of the generator. This will give you the true wattage of the motor.

A rule of thumb is that 1 horsepower equals 746 watts. by this rule the generator will start and operate the motor.

The formula to use is W = A x V. To see if an 800 watt generator will run the air compressor the amperage of the compressor must be stated.

Can a 120V generator run a camper's air conditioner?

Well all generators with a few exceptions produce 120 volts. What will determine if a generator will run your air conditioner is the number of watts the generator will put out. You need to learn the wattage needed by the air conditioner and also learn the max watts put out by the generator you have (Assuming you have one already) it the generator produces more watts that needed by the AC unit you are good to go. Not on the other hand if the generator you have dose not produce enough watts or you do not have one then it is a matter of buying a generator with the wattage required by the AC unit in your camper. Now if you are going to buy one I would also determine what else you would like to run from the generator (in addition to the air conditioner. Figure out the watts need by these items add them together with the watts needed by the AC unit. Then buy a generator big enough for your needs.
