Best 12 Volt Air Compressor: buying guide
To get the best portable air compressor for rv tires and other automotive tires, you need to watch out for some specific features. And these will be discussed in this section of the article-
- The Pressure
Each car tire comes with a specific range of inflation pressure as the unit of psi. Eventually, this should be within the range of psi that your air compressor works within. Otherwise, it will be hardly able to inflate your tires.
Also, keep it in mind that, the larger car tires are, the higher psi value they require.
- Inflating Speed
Making sure everything else goes fine, you definitely want to get done with the inflation job as quick as possible. And that’s where the point of inflating speed takes place.
Usually, it’s between 1.0-1.47 CFM as long as the inflating speed of 12V compressors is considered. For larger tires, go with high CFM. And vice versa.
- The Power Compatibility
As we’re strictly confined within 12v air compressors, it’s compulsory that all of these picks can be empowered with 12V DC outlets. But in case you want to work at home or garage with the same compressor, you need to check for AC-power compatibility(110V) as well.
- The Hose and Cable Length
These are two different cables/pipes we’re talking about, and length of each matters for different reasons. The length of the hose will let you reach distant car tires without moving the compressor itself. On the other hand, the length of the power cord lets you be near to the compressor while working on the inflation.
Making sure that there is no pressure distortion, go for a decent hose length. And the same advice would go for the power cord as well.
