Every microwave oven comes with a label indicating the wattage of the appliance. if the label is missing you can use a VOM  to check the wattage.
 However, there is a cool way to check by simply using a thermometer and a measuring cup and a container that can be microwaved.
 
 measure 4 cups of water
 record the water tempertaure.
 heat the water om high for 2 minutes and record the temperature again. Subtract the first number from the second and multiply the result by 19.5. 
The result will be your wattage.
