Query: CFM=POWER not psi

Cubic feet per minute (CFM) is the deciding factor for a compressors performance. If the compressor is not capable of producing enough air volume you will end up waiting and waiting to inflate. Most typical 12 volt air compressors on the market put out between 0.05 cfm and 0.07 cfm and cost anywhere from 9.99-100.00 and just don't do the job.If you are looking for a 12 volt air compressor with some CFM look for the " most powerful 12 volt air compressor" based on the CFM. 1.2 CFM - 1.9 CFM, more than enough CFM for the job, prices are around 50.00-100.00. Great to have for those " Oh no, low tire days. Inflates a typical tire in 2 minutes.
