It has a relatively quiet operation with a decibel level of 78 and takes roughly 2 minutes, 25 seconds to match the stated max psi of 135. With a one-gallon tank, it's extremely lightweight and portable at only 20 pounds. This cute little creature is the Senco PC1010 air compressor, a compact hot-dog-style air compressor ideal for small, precision tasks. If you want a little more capacity, Harbor Freight also has a McGraw eight-gallon hot-dog-style air compressor that hovers around $170. But if you don't mind those trade-offs, it's hard to argue with its comparatively low price. Overall, given its smaller tank size and higher noise level, this compressor is best for small, intermittent tasks. It also took roughly four minutes to compress entirely, which is a bit slow considering this is one of the smaller tanks we tested. While this should be more than enough for filling up tires and less demanding pneumatic tools, it's worth noting this item will likely struggle with more powerful impact wrenches and more demanding tasks. The tested max psi was 105-5 psi below the stated number. This could likely be reduced a bit by adding some quality rubber feet to the bottom of the compressor or setting it on a padded garage mat. However, despite being the lightest of the bunch, it's also the loudest on the list with a decibel level of 99. With a small three-gallon tank, this compressor is highly portable at only 15 pounds. Harbor Freight's McGraw hot-dog air compressor is ideal for those on a tight budget who still want the convenience of pneumatic power around the garage. We then hooked up a 1/2-inch Craftsman impact wrench and proceeded to take off as many lug nuts as possible, ending when the usable capacity was depleted.įinally, we assessed noise levels with a decibel meter, while ease of use, portability, and additional attachments were also taken into account to select the best portable air compressors. Testing the usable capacity, we filled each compressor to full capacity and disconnected the power. We assembled and weighed each air compressor model, complete with attachments, then measured the time taken and maximum psi achieved to fill each one from empty to full. The optimal choice for you depends on your individual needs and circumstances. Remember, no single air compressor is best for every task. If you're using your compressor in a residential area or enclosed space, consider a quieter model to keep the peace and protect your ears. Compressors can be surprisingly loud, and high noise levels can be damaging to your hearing (and bothersome to those around you). With one of the portable air compressors spotlighted here, you'll get the best of both worlds, with the ability to power small pneumatic power tools and pump up inflatables on the go.ĭon't overlook the volume of the air compressor. On the other hand, for intensive tasks such as powering pneumatic machinery in a workshop, you'll likely require a larger stationary unit. If you only need a compressor for on-the-go uses like roadside tire inflation, consider a smaller handheld model. Portability and size are also essential factors to consider. Higher psi ratings allow you to inflate tires more quickly, while a higher cfm rating means the compressor can power more tools simultaneously. These are measured in pounds per square inch (psi) and cubic feet per minute (cfm), respectively. Pay attention to the pressure and volume of your prospective air compressor. However, gas-powered models provide powerful performance when electricity is unavailable, such as at remote job sites or during roadside emergencies. Electric models are usually lighter, quieter, and easier to maintain, making them suitable for indoor use. What to Consider When Buying a Portable Air CompressorĮither electricity or gasoline typically powers air compressors. Whether you're a seasoned pro looking to upgrade your garage or an enthusiastic home mechanic in need of your first compressor, we've got you covered. We may have sacrificed some brute power, but we gained a ton of convenience. While large industrial models provide the utmost power and performance, most of us will never bolt one of those to our garage floor.įor this test, we stuck with portable models that can be moved where you need them. Our mission was clear: to sort through an ocean of models and uncover the portable air compressor that provides top-notch performance for automotive applications.
