how many watts should a microwave have?

A slow microwave oven has 300 to 500 watts. An average watted oven has 650 to 700 watts or more. A high wattage oven has around 800 watts or more. A very high wattage oven has 1,000 watts or more. Contrary to popular belief microwave ovens are not radioactive. The “microwaves” released during cooking energize water molecules which trigger friction and lead to heat. Today over 90% of homes in the United States have a microwave oven.
