Pros: There is no job too big for the California Air Tools' extreme power and large tank. Features CFM rating and a pump that doesn't make a lot of noise when in use.

Cons: Weighs 90 pounds, making it larger and bulkier than other models we tested.

Summary: Though a good choice for users who need a rugged machine for large jobs, the trade off is less portability. The large tank and CFM rating of this machine make it perfect for larger jobs.

Pros: Rugged and powerful. Stands out for being ready to use faster than similar models with its quick-fill tank that is full in 67 seconds.

Cons: Some of our testers noticed that this model is somewhat sluggish to start in cold weather and requires being warmed inside to get it going.

Summary: Offers power and performance for a middle-of-the-road price, but the Makita is an all-around better machine.

Pros: A compact model by a trusted brand. Offers excellent performance for its size and affordable price.

Cons: Tank is slower to fill than larger models we reviewed.

Summary: For the size and performance you get with this rugged portable air compressor, there isn't a better model on the market today.

Pros: Budget-friendly model that is perfect for minor jobs such as inflating and driving tools that don't require a lot of pressure

Cons: We found that the hose is somewhat brittle, which makes it prone to breakage.

Summary: An affordable portable air compressor that is the best choice for small jobs and some tools, but the Porter-Cable's performance makes it a better deal.
