You need to turn on the turbo switch.
its AC, volts times amps equals volt-amps, not watts
you have to include the power factor for AC
so, Watts=average{v(t)×i(t)}

plus they probably rounded something off, so it won't be exact anyway
3A is probably for the appliance rating...
Most countertop blenders use universal motors. These have a very high (unloaded) speed. Even at full speed (frappe?) with no load it may very well draw considerably less than 500W. Get chopping, load the motor up and watch the power draw soar. The 500W (approximately .67 horsepower) is probably a peak measurement, like many vacuum cleaners are rated. The commutators and brushes are not rated for this duty continuously.
Even scarier is these types of motors can tolerate surprisingly amounts of over volting either until their bearings fail, the connected load destroys itself or the commutator goes up in a spectacular ring of fire!

But, a volt is a joule per coulomb, and an amp is a coulomb per second. So, volt-amps are joule coulombs per coulomb second, or joules per coulomb.volts times amps equals volt-amps, not watts
Starting amps are much higher than running amps so your blender may consume 500 peak amps in starting. But as it continues to run the current draw may drop down to 300 Watts.
false advertising!
(yes it does say peak)
I desperately want a blender that requires 500 amps to start! :awe:
turn it over and the motor label says 3 amps. 3 amps * 120 volts = 360 watts. where does 500 watts come from?
