I use this inverter in my work truck primarily to be able to charge batteries in between jobs. That being said this 3,000 W inverter will run my electric air compressor and my 12-in miter saw. I do have to start my truck for the compredsor to run without slowing.
* the system in my truck that runs this inverter has its own alternator under the hood which feeds two giant AGM batteries which then feeds power to the inverter so your results May Vary.
