micro-air easy start

watts=volts x amps so if you lower the voltage, amps will go up. I read the FAQS at Easy-Air and it mentioned slowly raising the voltage. I don't think they're telling you the whole story on how it works, probably at the risk of someone making a home-made one and them losing out.

The micro-air mostly likely uses a thyristor to control the AC waveform, same thing that's used in light dimmers. It's not as simple as the basic power calculation. If they lowered the voltage via added resistance the heat dissipated by the micro air would be big, and if they did it with a transformer the size, weight, and price would increase a lot.
