Best Portable Air Compressor in 2018

Beefing up your tires or inflatables, blowing away debris and powering pneumatic tools is easier when you own the best portable air compressor. For me, this is one of the handiest tools in a home workshop.

I like my 6-gallon machine for its all-around usefulness. It stood by my side during small spray painting job, it fueled many garage and household applications and even saved me when I punctured my tire during a road trip in the middle of nowhere.

Here's a list of Best Portable Air Compressor

From basic models with few accessories to high-end units equipped with all accouterments, a portable air compressor is simply a DIYer’s best friend.

Different Types of Air Compressors

Air compressors come in all shapes and sizes, but they can all be grouped into a few basic types.

Electric or Gas-Powered

Air compressors are either electric or gas-powered.

  • Electric-powered machines can be plugged either into an ordinary wall outlet or your vehicle’s cigarette lighter socket. Some are AC/DC adaptable, but if you have specific requirements, it’s better to check before buying.
  • Gas-powered air compressors are developed majorly for commercial applications and are rarely portable. However, they bring versatility in situations where an electrical supply is unavailable.
  • Oil-Lubricated or Oil-Free

    Portable air compressors can be further broken down into oil-lubricated and oil-free machines.

  • Oil lubricated units are typically more powerful and have longer lifespans. On the downside, you’ll have to check the oil level constantly and change it regularly. This is a simple maintenance routine, but it’s time-consuming and costly in the long run.
  • Oil-free compressors comprise Teflon-coated cylinders that need no lubrication, thus no maintenance. Albeit you cannot replace the Teflon lining once it has worn out, the process is slow, and a high-quality portable air compressor will last for many years.
  • What to Look for In a Portable Air Compressor

    1. CFM Factor

    The cubic feet per minute -  or CFM factor - is perhaps the most critical feature to consider. It determines how fast your portable air compressor can supply air to the tools. If your pneumatic tools use the air faster than the compressor can provide it, you’ll have to stop working and wait for the tank to refill. Portable air compressors have CFM ranges from 0.6 to 2.8 and in my experience, the higher, the better.

    2. PSI Factor

    Although acclaimed by DIYers, PSI (pounds per square meter) isn’t as important as it seems. Most manufacturers test how their machines perform when used with common tools, and almost all models provide plenty of pressure for your domestic tasks. On the other hand, a higher PSI allows a smaller tank to hold more air, which ultimately improves performance.

    3. Horsepower

    The horsepower rating is another figure that raises no concern, but it can give you a sense of the unit’s power. Typical horsepower ratings of portable air compressors vary between 1.5 and 6.5 HP but don’t mistake this number for the CFM. It is the latter to provide power to your tools.

    4. Tank Size

    Most portable compressors come with tank sizes between 1 and 6 gallons, except for those that are tankless. An average unit with a 3-gallon tank is usually sufficient for inflating tires, inflatable toys, or beach mattresses but a 6-gallon machine brings an all-around versatility. Powerful compressors with high CFM may need no tank at all to deliver exceptional performance.

    5. Features

    Besides all mentioned above, there are a few other features you should consider.

    • Multiple couplers: a few portable air compressors come with two or more air hose outlets. These are great if you want to use the unit for various parallel tasks.
    • Oil-free pumps: unless you’re using a small compressor for heavy-duty projects, an oil-free unit can save you the hassle of maintenance.
    • Noise level: my advice is always to check the noise level of the model you like. Most portable air compressors emit between 60 and 80dB but for your comfort, choose the quietest unit that meets your needs.
    • Portability: as weird as it may seem, some portable air compressors are just more portable than others. While a nice heft is essential, shape and size also matter.
    • Accessories: if you’re investing in a portable air compressor, odds are you’ll want to use it for the most diverse tasks. Choose a unit equipped with various nozzles and accessories, and that can adapt to most domestic needs.
