Close all the windows in the pop-up camper. These windows are made out of mesh instead of glass, however there is a vinyl covering on the interior to prevent heat from entering or exiting. Closing the windows helps prevent the cool air from escaping.
Place the portable air conditioner in the middle of the pop-up camper. This gives the best air circulation. You may not use a standard window unit, as the camper is not strong enough to hold up the device.
Extend the power cable out the front door of the camper. Even with the cable running out the door you should be able to close it without too much trouble.
Connect the power cable to an extension cord. You are connecting the air-conditioner to a portable generator, and these are often noisy. The further away from your camper you are able to place it the better. If you are in a small campground it may not be possible to use the device if you are in close proximity to your fellow campers.
Connect the extension cable into the generator and power it on. This provides power for your AC unit for several hours (depending on the brand of the generator).
