Home air pump?

I have 5 air compressors I have accumulated over the years. For a plug in, I am blown away by the quietness (60 DB) of the California Air Tools 1hp I just bought. All of the others (3 Craftsman, a Porter Cable and a Tradesman) are so loud you need hearing protection when using them. I'm probably going to buy a 2nd CAT for the barn; I have the 6310. $199 on Amazon. No idea how they make it so quiet or why the others are so loud.

I have been using Porter Cable air compressor for years. Strong enough to use with air tools.

I recently picked up this unit from Home Depot. $169.00, 4.6gals and VERY QUIET. I had a pancake before and it would make my ears bleed.

While we are on the subject, I also recently picked up this digital gauge / tire inflator. This, plus some quick releases and the compressor above make dialing in perfect tire pressures a snap.

Picked up a 120 volt Husky from Home Depot for $29.99. Great little pump for the garage. If you don't have a pump currently why don't you use the pump that porsche provided with the spare?

Can anyone comment regarding rate of inflation regarding any of these units? I was reading Amazon reviews, and one comment reported to expect a 3 minute inflate time from flat to 30 lb pressure. Maybe I'm spoiled by gas station air fill rates, but does any consumer oriented product come close?

This is a gallons issue. Your compressor will give you good high pressure for about the first third of the tank. So a 3 gallon tank will quickly give you 1 gallon at high pressure. After that it has to pump the pressure in the tank back to a good level.
The issue here is how many gallons it takes to fill your car. I've never done the math or looked this up, but for arguement's sake let's say it needs 2 gallons, and you have a 3 gallon tank on your pump.
Issue number one, is your tank already pressurized? If you use it a lot, as in several times a day, then maybe yes. If not, then it should be stored empty. So first off you must fill the tank, that would take a solid 60 to 120 seconds depending on the power of the pump, let's say your pump took 90 seconds (roughly 30 seconds per gallon).
Then when you fill your tire you get 1 gallon pretty quick and your tire is half full. At this point the pump kicks in and it's trying to fill 2 gallons (1 gallon from the pump tank, and 1 gallon for what's needed to finish off your tire). If you sit there and keep the nozzle connected to the tire, the pump will need close to 60 seconds to fill both the tire and the tank.
A giant 80 gallon shop compressor would be like the gas station, the entire 2 gallons would be filled in a matter of seconds. This is the difference between a large expensive loud compressor and a small cheap possibly quieter compressor - convenience.
Of course you could get a large quiet screw based pump, that will run you about the price of a track ready used Miata

Amazon.com: Viair 00073 70P Heavy Duty Portable Compressor: Automotive
I have the Viair 70P and use the cigarette lighter as the power source with the engine running. I use it for all my vehicles and it works fine.
