If you're stranded on the side of the road with a dead battery, you may be wondering if you can boost a car with an air compressor. The answer is yes, but there are some things to keep in mind before you try this method.
First, make sure that your air compressor is powerful enough to start the car. A small, portable air compressor may not have enough power to get the job done. Second, check that your air compressor has an adequate supply of compressed air. You'll need around 150 PSI to start most cars.
To use an air compressor to start your car:
1) Attach the positive (red) jumper cable from the compressor to the positive terminal on the battery.
2) Attach the negative (black) jumper cable from the compressor to a metal ground on the car away from the battery (this will help prevent sparks).
3) Turn on the air compressor and let it build up pressure (this may take a few minutes).
4) Start your car and let it run for a few minutes before disconnecting everything.
