I have an $80 Viair model which I carry with on trips. It is much better than any small compressor I've had before.

I also have a pancake compressor which I use to blow out the water to winterize (it has adjustable pressure regulation), and will also use to top off the tires at home or in storage. The Viair says you should have the engine running when connected to power, and I'd rather just connect this to power, pump it up, and then use it without power.

Both together cost about half the "recommended" compressor.
