I think the "catch" to the cig powered ones is the low number of beats
per minute. Yes each impact may be 250ft/lbs but due to the limited
power at 12V you don't get that many "hits" per minute. A real unit
will deliver 250 ft lbs each impact with many impacts per SECOND.
When you are removeing a stuck lug nut it may take many many impacts
at 250 ft lbs so it would take forever with the 12V unit.
I have a 1/2" 120V electric unit and it is OK for medium jobs, it can
take a minute or two of "hammering" to get a stuck lug nut off. If you
want it for those really stuck bolts, you should get a beefy unit.
If your compressor has a limited CFM rating then again that translates
into limited beats per minute and not limited ft/lbs.
