I have an old 250 watt kitchenaid that I got from my husband's grandmother. Besides the size of how much you can make, what is the actual difference between mine and say a 5 or 600 watt...I am starting to bake more cakes and if getting a newer one will help......I'm all for it!!

more wattage...meaning bigger loads of icing!!! Also better equipped to handle heavy doughs etc...I would purchase a bigger one!!

What does more wattage actually do when mixing...

Higher wattage usually means more power, although for certain items (like vacuum cleaners), that doesn't necessary hold true.

A 600 watt motor can handle larger and heavier loads than a 250 watt motor.

Doug can probably provide an excellent discourse on this subject.

Sherri

more wattage = more power

so you will be able to mix larger batches of whatever you are making
