Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

This review is from: VIAIR 300P Portable Compressor (Misc.)

After burning out two $20 compressors from Harbor Freight, I decided to research online and buy something that really is powerful and works more than one time. The Viair 30033 330P is certainly powerful enough for my little Civic wagon. I don't think it warrants the $170 price tag, but it does seem to be what it claims to be online. There's no way the cords are long enough for a bigger truck or RV. I advise installing a dedicated, hard wired compressor in a big vehicle. The carry case is a cheap nylon bag and the overall quality is high for China: low by my USA standards. You can get it delivered quickly though. Mine arrived next day.

5.0 out of 5 stars Better Than Expected..., June 27, 2008

Ideally I wanted an on board air compressor in my new FJ Cruiser for going off road. But I needed an air compressor now, so I opted for the portable kit thinking I would install it at a latter time. Now that I have it in hand and have used it, I am most likely going to keep it as a kit. It works perfectly on the FJ's 32" tires and on my wifes Honda Civic it fills them within seconds. When putting air in bikes, it puts out so much air you have to watch out not to blow the tires. I showed a friend of mine how well it worked and he ordered one for himself that same day.

The Viair 300 air compressor is an excellent product for both airing down and pumping up my 30 inch tires on my Jeep. You can use it anywhere with the 12 volt cable and pumping tires up is quite a bit faster than other 12 volt systems. I highly recommend it.
