You're an idiot. First off, there are ZERO 115 volt circuits here.
Secondly, everything that runs on standard AC that relates to raw power
is declared in Amps.
Look at vacuum cleaners, and the hand drill.
Anything that competes with other makers that runs on a motor, competes
with each other over how fast or how strong or how well it can do the
A dremel tool talks about top rotational speed as that is more important
than shaft torque.
Drills and vacuum cleaners refer to the amperage of the motor.
So, YES it DOES mean EVERYTHING about how much power it has in a world
where the source voltage is known.

You are both wrong.
With AC, Volts x Amps only gives the power with a resistive (heating)
If you have an inductive load this is no longer true. (ie a motor.)
If it was a pure inductor, you could draw as many amps as you liked
and no power would be consumed.
Pure inductors only exist in theory BTW.
If you connect a capacitor across the mains, it will draw current but
no power will be consumed (virtually).
Pure capacitors (as near as dammit) exist.
The pair of you study this:
I don't know where you Yanks get educated. God help America!

First of all, I'm no yank.
Second of all, That's what I was aluding to when I said the amperage
rating REALLY doesn't tell you how much power a device puts out. It is
an indicator, but does not take into account things like efficiency,
power factor, and a whole lot of other things that most people don't
even think about, much less understand. It ONLY tells how much current
is being drwn
As for no 115 volt circuits, OK, say 330 and double the wattage
(1380), or 240 and it is 1440 watts.
All the more reason AMPERAGE is not a good indicator of power output -
it doesn't tell you what voltage it is based on.
Wattage does. And wattage takes into account power factor, inductive
and capacitive reactance, etc. - making it a much more reliable
indicator of power output - but still does not address the efficiency.
Horsepower (or foot lbs torque at rpm, or newton-meters torque at RPM,

You guys are idiots. Amps are used to make guitars loud. The louder
something is the more powerful it is. So if I want a powerful motor I
want one that goes to 11 amps 10 is for chumps.
why? Because 11 is greater than 10. Rock and Roll.
Also there is an energy drink called Amp, so there!
