I too have the Porter Cable 110V pancake compressor and use it as a backup for my big shop compressor - I don't carry it as it is fairly heavy at about 35 pounds with hoses and air chucks but even worse, a pain to safely store. There is also a little Craftsman 12V emergency compressor that will work if I really need to air up a leaky tire.
With that said, I looked at the VLAIR line on Amazon and other sites and was dismayed to find that many of their models are being manufactured in that Far Eastern country with a less then stellar reputation for quality tools while other models manufacture countrys are conspicuously not mentioned. Yeah, I know that's not a reason to condemn them but it sure doesn't make me happy.
