I've had a Honda 2200i for about two years. I use the generator to supply AC to our RV when off the grid. The Honda is very quiet and very reliable and it starts on the first pull every time. It will start and run a 15,000 BTU air conditioner with a soft starter like Easy Start. However, it won't run much more than the air conditioner, especially if the air conditioner is cycling on and off. If not running the air conditioner, then you can run the fridge, brew coffee, dry hair, run microwave, etc, but none of those high demand items at the same time. We've run it for 24 hours at a time with an extended run tank. Last week it ran for 20 hours straight, running the air conditioner, and used 4.5 gallons of fuel. If you are careful not to have any demand for power, except the air conditioner, then you can use the eco switch so it idles down at night when the air conditioner turns off. It uses zero oil.
I like the 2200 for its size. It fits under the tonneau cover of the truck and I can lift it in and out of the truck by myself. At this point, I'm glad we didn't opt for a larger generator for our use.
