Bought this unit to fill the 5000 lb air bags I just installed on my truck. The air bags are rated to a max of 100 psi which this does effortlessly. It is all metal construction, quiet and well made. Should last a lifetime. Don't waste your money on a on board air compressor for your air bags...this does it perfectly plus it has additional uses on or around the vehicle. Handy carry bag and very long 12 volt cord. Solid purchase and price AA.
VIAIR 300 P Evaluation
I have use the air compressor only once so far but it was very easy to use. Airs tires very quickly. Just remember to set the connection to inflate and not deflate, both very easy to use. I was initially concerned the coiled hose would be difficult to use. It was easy. The weight of the compressor was enough to keep it stationary while the hose was pulled.
