Does anyone have a guess as to what kind of power a fan like this draws, on
low speed?

The product manual is on Amazon and says 120 volts, 0.52 amp (i.e., about 63
watts).

Presumably, that is for high speed. As a rough guess, the lowest speed
might be 1/4 of that.

I am very ignorant about electricity. Volts x Amps = Watts? Very good to
know.

That's 63 VA

NOT WATTS !

Jeez, talk about beginner's mistakes.

Except it's wrong for AC

V x A = VA

Yes, by his dad. Isn't it obvious? He bounces around all the
electronics newsgroups while doing his best to piss everyone off, and he
hates America with both neurons.

For AC this is only true if the volts and amps are in phase; otherwise the
watts can be somewhat less than the volt-amps.

Not a mistake, a simplifying assumption. We don't know the phase
relationship between the voltage and the current. The power is 63 W or
less, we don't know how much less. Nor do we know why he wants to know the
power, or whether he's actually concerned about power limits or current
limits.

At a unity power factor yes, but as the power factor drops (reactive loads
like motors and such) the wattage will be lower than volts x amps would give
you.

I'd plug in the one I've got here and check, except it's in the "junk
box," having died long ago -- in fact, not that long after I bought it,
as I recall.
