Craftsman C3 19.2 volt Cordless Inflator —
I like the C3 tools and this one meets my needs really well. It is easy to use, accurate and will allow you to keep your tires at the proper inflation level in just a few minutes per week or at whatever interval you choose. Yes, it is noisy, but it is a small air compressor so you will have some noise. It comes with enough attachments that you should be able to inflate about anything you have. The built in digital gauge does agree with a commercial quality air pressure gauge that I first used to check its accuracy. When the trigger is released the gauge does go down about 1to 2 PSI, but the reading before you release the trigger is the one that agrees with the commercial gauges I used. The air hose clamps onto the air valve stems so one-handed operation is easy.
