Yep – really handy if you like fixing stuff. You can get air tools like sanders, polishers, wrenches, chisels….. These seem to last for ever as there is no motor in them.
If its just for tyres – a basic compressor is fine. Basic is also fine for impact wrenches, spraying – BUT the small tank will mean the motor cuts in a lot more often and do your head in.
They are NOISY! The use a LOT of current. On startup mine draws close to the 12A breaker in my garage so I have to make sure not to have much other stuff running at the same time. You should change the oil in them from time to time (like an engine). If using tools an in-line oiler is a good idea (saves you having to remember to oil the wrenches etc).
Got my latest one from Machine Mart in a sale. It’s fine. The also did (do?) a bundle of common tools that’s good value (tyre inflator, wrench, basic sprayer…). Remember to get a presta – schrader adapter if you’ve got prestas.
