they all use compressors that are belt-driven by a 1.1 kW electric engine like this one:
wouldnīt such a compressor be better for me? itīs as fast as the kilby.
How can fuel consumption increase? When the compressor is not running (pumping air) its not taking any load from the engine. It uses a clutch just like your A/C compressor. When your A/c isn't running, its not going to take any extra power to turn it. I would say your friend are not exactly sure what they are talking about
I really doubt that compressor is as fast as a Kilby, being that its a single cylinder but who knows it might be, do you have the Specs on it? Although even if its not as fast as a kilby it might be fast enough for you.
Also that compressor is going to pull 90-100 amps from your battery. Your not going to run it very long with your engine running before your battery goes dead. So i would say both of them need the engine running to air up your tires.
If that compressor suits your need better, I am all for it
But if you want a bad ass electric compressor get one of these
8 CFM @ 100 PSI with a 90% duty cycle
