Ditto on the Viair. Most small compressors advertise "max psi", but when you are airing up something like an air mattress, truck tire, or similar, you want CFM also. Not just how much pressure the pump can build but how fast can it deliver the air?

I have used this bring all 8 tires on the truck and trailer from 15 to 65 and 80 psi respectively and it didn't break a sweat.

How long does it take the compressor to air up a tire from 15psi to 80psi?

Thanks, Ken
