My gage on the air pump sent to me does not read the correct pressure. You may want your own gage. This is more for the need a few pounds jobs. The pump seems to take a long time for just a few pounds, but it does do the job with a quality clip were it counts; at the tire valve attachment.
This portable air compressor has a small electric motor that compresses the air in a small attached cylinder tank. It can be plugged into a 12V car system for on-the-go repairs or inflation. It's ideal for car and bicycle tires, sports balls, airbeds and inflatable toys, etc. Because it can be powered through a cigarette lighter in your vehicle, it is incredibly versatile and a lifesaver in some instances.
