12-volt air compressors are one of the most commonly used devices for lightweight jobs. Industries generally use engine-driven air compressors that run off of natural gas. They use these particular devices to save on the high-energy costs associated with running an air compressor. For those of us who only use an air compressor occasionally, a 12-volt air compressor is probably the best.

All terrain vehicle enthusiasts often use 12-volt air compressors for their off-road needs. You can often find adapters that enable the air compressor to be powered or charged from a vehicle's cigarette lighter. This is a handy and accessible device for people who may not otherwise be located near an electrical power source in which to feed energy to their air compressor.

12-volt air compressors typically work in the same way as other models. Most of them, especially those that are certified by the American Society of Mechanical Engineers (ASME), have advanced safety features. One difference in 12-volt air compressors and other types of air compressors is the power of the air emitted. Most regular users do not need the industrial strength powered air compressors for their everyday use.

Other than ATV enthusiasts, many other uses of 12-volt air compressors exist. People use them, along with attachments, for a variety of uses around the home. They can be used to power nail guns, staple guns, wrenches, spray guns and just about any other kind of tool you can think of. Some homeowners may wish to purchase a 12-volt air compressor if they often have do-it-yourself jobs while others prefer to rent a device. You can usually find devices for rent at most home improvement or hardware stores. It is important that you buy or rent an air compressor that has been certified by the ASME. Otherwise, you may receive a product with substandard workmanship that has not been tested for quality and safety.
