How does inverter heating differ from a regular microwave?

Instead of switching the magnetron on and off at full power, inverter models vary the power continuously. That gives steadier low heat for defrosting and melting without hot spots.

Is 2.2 cu ft big enough for a family?

Yes. It fits large casserole dishes and full dinner plates, which is the main reason to pick this size over a 1.2 to 1.6 cu ft model.

Does it need special ventilation?

It is a countertop unit and needs clearance around the vents, as any microwave does. Leave space at the sides and back so heat can escape.

What are the preset menus?

Popcorn, Reheat, Potato, Bacon, Chicken and Bread. Each sets power and time for that food, and you can still cook manually.

Is there a child lock?

Yes. The child lock disables the control panel so children can't start it by pressing buttons.

It is designed as a freestanding countertop microwave. Built-in use would need a trim kit and enough clearance, which this model does not specify.

Our take on the 2.2 cu. ft. 24.4'' Microwave Oven in Stainless Steel

The Toshiba WSI-EM22AST is a 2.2 cu ft countertop microwave with 1200 watts of output and inverter heating. Inverter power holds a steady low level instead of pulsing on and off, which helps with even defrosting and gentle reheating. A humidity sensor and six preset menus (Popcorn, Reheat, Potato, Bacon, Chicken, Bread) cover common jobs, and a child lock keeps the controls safe around kids. It suits large households and people who cook for crowds; against smaller 1.2 to 1.6 cu ft rivals it trades counter space for capacity and power.
