Just don't go for one of those plug-into-your-cigarette-lighter portable
tire inflators. They are super slow. Plus they don't have a tank
built-in, so there is no reservoir of compressed air to rush out the
spray nozzle. They simply pump air, very slowly, and can do so at high
pressures.
Here is an example of one:

You could successfully use one of these if you combined it with a
portable air tank, but I think it would be too slow and would frustrate
you.
