i'll let you how accuate the analog gauge in the coleman is, because i'm sure digital is better but the digital one can only be used with the 12volt (so car has to idle while i pump tires! bs). While the coleman has a built in battery in it, so it can be portable or charged either way (house plug too).
check back in 24 hours or less. My sidewall pressure is 51 so im going to tip toe to 55 psi or even 60 depending on how good this coleman pressure is. I have a power battery pack station air compressor as well but its gauge is way off (ok so i lied i got three!) so I rarely use it because recalibrating with the digital one ain't fun at all so hopefully this coleman i just bought will be good enough.
If your reading this, then good for you, your saving some gas because your here.
