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.

Well, the review at that site calls it a 0.52 amp fan. At 115vac, that's
59.8 watts. I assume that is on maximum speed.-- GO LUNA ROSSA! Beat the Kiwis.

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.

well, if you read the PDF file, .52 amps.
