I do not believe the wiring ETI uses on 12v receptacles is heavy enough gauge for 15 amps. Most people use these outlets for charging electronic items such as phones or tablets. Reace told me that if I wanted to use a small inverter to power a television when 120v AC connection was not available, not to exceed a 150 watt inverter as the wiring was to light to handle much more than that.
Again, I do not know which model compressor you have or what your intended use is, but it would be a simple task to add a 12v outlet, wired directly from the trailer's battery or the tow vehicle's battery using wire more than heavy enough to supply 15 amps. It could possibly be mounted just inside the door of a storage compartment, to the bumper, or most any location that would be convenient for you. And it would be relatively inexpensive to do so. I, and many others on this forum can provide all the advice needed to do this, assuming you have at least "novice" status using tools and are comfortable doing this work. But it would be helpful to know how and where you would like to use the compressor.
