All the various compressors with built in gauges I've seen go up to
something silly for cars. Even the one supplied in my car toolkit. Reads
up to 150 psi, when the maximum pressure ever needed is 34 psi.


Some of the small space saving spare wheels are around 60 to 70 psi.

I've had a cheap compressor fail when I've used it for too long a period
(much longer than the instruction manual recommended without leaving it
to cool) and the cylinder got very hot. I would expect a very short life
expectancy from some of these units when working at 150psi.

Looking at some Youtube videos where these compressors are dismantled
the working parts mostly seem to be the same generic design, possibly
all produced in the same couple of Chinese factories.
