Question: what is the difference between 900 and 1000 watt microwave?
Answer: A 1,000-watt microwave will cook quickly and efficiently. Microwaves with 700 watts or less are slower and may not cook evenly. In general, the higher the wattage, the faster the cooking time. ... In your case, the additional cooking time is not dramatically increased because the difference between the wattages is slight.
