Only looked at the Ridgid link.
Claims to be fastest from flat to full, but no time stated.
It doesn’t show CFM, which is the bane of small inflators.
Would appreciate test report after you’ve given it a workout.
Ridgid is good... Took four 225/75/15 trailer ties from 28-30 PSI to 70 in a few minutes (1-2 minutes each). Pulled down a 4.0 Ah battery from 4 bar to 3 bar.
Not tested elsewhere...
Have not tested the Makitas yet.
The Puma is a different application (running nailers in the field). It is good so far... I may add a piggy back tank.
