Before deciding on a power source, evaluate your working environment and its available power sources to determine which one is best for your needs.

Electricity powered: Electrical powered air compressors run off of either 110V or 220V outlets. Electric compresso​​rs generally have fewer overall parts and are incredibly efficient throughout their lifespans, often lasting many years before showing signs of wear and tear or needing to be replaced. They’re usually lighter in weight than other compressors since they lack an engine assembly, making them easier to lug around in case you need them at remote job sites. The only downside would be that you need to plug it into an outlet, so if your work area is not near an electrical outlet, then it becomes somewhat impractical.

Gas powered: Gas powered air compressors offer portability and offsite convenience because they don’t require an electrical outlet — however, they can be quite temperamental due to the different components necessary for operation (including fuel filters). Additionally, gas engine parts often need regular maintenance and can sometimes require frequent repairs if the compressor is used frequently over long periods of time. For DIYers working indoors or in enclosed spaces — this option may not be the best because these models tend to be noisier than their electric counterparts.

Battery powered: Battery operated air compressors place less strain on your work environment as compared with gas and electric ones since these models don’t rely on external power sources or mechanics (just ensure that compatible batteries are available in order for proper functioning). Since they’re reliant mostly on rechargeable batteries as opposed to pneumatic pressure and/or combustible engines/fuels — these units may sometimes struggle with providing sufficient pressure depending on the model being used (ask manufacturer recommendations before attempting larger projects).
