Hi,
If you go to Costco or Home Depot, or another hardware store, you might find some 4,000 - 5,500 watt 'portable' generators in the 120 pound size range, that will be extremely noisy! Think about 80 Db, or louder than your kids play the radio.
Others considerate of the neighbors will buy a pair of Honda 2000 watt inverter generators. They slow down when load is low, and speed up when more power is required. Thus under small loads, such as battery charging it will be REALLY quiet, and get up to about 60 Db under full load when running the microwave.
You can link together a pair of the 2000 watt generators and get the 4,000 watts that you need to meet the air conditioner start up wattage requirements. While the A/C is running, you will also be able to run the microwave.
Small loads like a 90 watt TV, laptop, cell charger are not big deals for a 2,000 Honda, that is actually rated at 1,600 watts with a 2000 watt 'surge' rating for 30 minutes.
Also the Honda is only about 50 pounds, so light enough for one person to move it around. They are easy to steal, so lock it up too! Some have even had the handle cut, and thought that their generator ran out of fuel, but in fact someone had cut it, loaded it into a pickup, and unplugged it as they drove away with it!
Mayberrys.com is a good place to buy one, along with the cord to link together two of them to a RV style plug.
Have fun camping and dry camping is the best!
Fred.
