A portable microwave oven in which the magnetron used to generate microwave energy is operated at half its rated load with power supplied thereto through a special power supply circuit which is designed to limit input current to 7.5 amps permitting a lighter transformer to be used and permitting the magnetron to dissipate reflected power under no load condition. The oven also includes an improved tuned waveguide and an improved stirrer for equally distributing energy in the oven cavity.
