Compare that to a similar conversion for a 700-watt microwave. A 5-minute recipe would require an additional 3 minutes of cooking time, and a 10-minute recipe would need about 6 minutes longer.

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.
