Can you explain the difference between an air compressor and a portable compressor?
assistant
An air compressor is used to compress air, while a portable compressor can be carried from one location to another. Air compressors are typically powered by electricity or gasoline engines, whereas portable compressors use electric motors. Air compressors are generally larger than portable compressors and can produce higher pressure levels. Portable compressors tend to have smaller tanks and less pressure output compared to air compressors.
