I use this all the time at autocross events and airing up anyone's tires at the house, so much faster than hooking up the big compressor and messing with the air hose! Decent price. You could also go down to the M12 model and I'm sure be fine, but this one has higher specs.

Driving out to do the hack is, in my opinion, a waste of time and gas to save $20.
I live about 2 miles away, I'll gladly save $20. Or better yet I'll do it in my company vehicle while working.

I found the a solution I use these: Locking Tire Air Chuck,Brass Tire Inflation Hose Adapter,Tire Nozzle With Tire Valve Threads,Unscrewed Connection Converted To Locking Connection,No Air Leakage On Chuck Air Compressor Pump Clip they are $6 for two of them they are great.
Mine does the exact same thing. I put on a brass locking air chuck and it still does it. I've been curious if mine is defective too.

Quote from Shortbrant :
I don't know if it's just mine, but mine always comes up short when airing up my tires. This thing will pause each time to take a steady reading, then it'll start pumping, the display will show it exceeding the set psi, then pause pumping to read, which will show like 5-7 psi less than what it showed while pumping, only for it to finally think it got close, shut off, sit for a second then still read 3-4 psi lower than what I set it to. Not sure if everyone's is like that or if mine is defective. If yours doesn't do this let me know so I can try file a warranty claim on it.FWIW, my m12 inflater doesn't do this, it happily chugs along to the psi I set without needing to constantly pause to take readings, and actually stops when I hit the psi I set. Only downside is it's slower and there's no memory function for pressures you typically use.

The first one I had did this. Turned it into Milwaukee for warranty claim and they just replaced it with a brand new one. The replacement has been rock solid.
