Portable tire inflator recommendation?
For auto and trailer tires where the max PSI is 44 PSI or 60 PSI, what is a good, well built tire inflator that has a hose that screws onto the tire (I want it to screw onto the tire valve, because hu...

Note that these portable on demand compressors all have passive air chucks. if not hooked to a tire they still bleed air out the tire chuck so as to not build pressure, as there is no tank to hold it.
I thoroughly despised the screw on chuck which came with my masterflow Mv-50, and replacing that was the reason I did all the modifications I did to it.
The screw on Chuck still had a quick air release which required being a precise angle with no torque applied, so it basically had to be screwed on, held in place during inflation, then unscrewed quickly, and anytime I was threading or unthreading it it was bleeding pressure.
My masterflow mv-50 now has a 1/4 NPT receptacle in head, a better coiled airhose, and a passive locking tire chuck with lever. I drilled a small hole thought the portion which depresses the valve so it cannot build pressure in the line.
Other modifications to this compressor were removing the horrid crimps inside the endcap to relay, adding strain relief on the cord, a 80MM comnputer fan to blow over the head, Adding 45 amp anderson powerpoles to the 14awg power cord, and putting grease in the big air pockets between cylinder and finned head for the better transfer of heat from the cylinder.
Also the air filter which came with it, had a bunch of plastic mold flashing on the inlet holes that severly restricted flow, easily remedied with a razor blade.
It can pull 16 to 19 amps depending on the voltage it receives. I was considering replacing the 14awg with thicker, but Time to fill is not really an issue, so higher voltage and a faster spinning motor is not really required in my use.
I've not actually measured the voltage drop at the relay in the endcap when running, but I have run it directly off of my adjustable voltage power supply whose range is 13.12 to 19.23. It sounds kind of sick at 13.12v input voltage and much faster and smoother at 15.5v.
