As the leader in cutting-edge microwave technology, Panasonic microwaves allow you to now poach, braise, and steam dishes to perfection with their Inverter Technology™. Unlike conventional microwaves that rely on pulse-on, pulse-off power at lower temperatures, Inverter Technology™ delivers a constant stream of cooking power at any setting, which means no more cold centers in your food. Combine the Inverter Technology™ with the new Cyclonic Wave™ feature and you get a the quickest and most effective way to enjoy dishes via a method that preserves the nutrients and flavor of the food. The Panasonic 1.6 Cu Ft 1250W CT/Built In Microwave includes both of these innovative features. Further, it incorporates a Genius Sensor™ that measures the amount of steam rising from the food to precisely calculate the correct cook times and power settings needed for what is being prepared. The 2.2 Cu Ft 1250W CT Microwave features the Inverter Technology with Turbo Defrost™, cutting down defrost time, and includes 18 preset menu items settings. The 1.2 Cu Ft 1200W CT Microwave also includes the Inverter Technology with Turbo Defrost™ and though it has a more compact inverter power unit that occupies less interior space, it still gives you the largest cooking capacity possible, making it perfect for dorm rooms and apartments.
