Overview
An inverter power supply gives this Panasonic a constant stream of cooking power at every level instead of pulsing on and off. A steam sensor then sets power and remaining time automatically, and the stainless steel body fits a counter or a trim kit.
Even heating from edges to center and sensor-guided cooking are the reason to look at it. The warranty is brief, and the title and spec table disagree about wattage because one figure is cooking power and the other is input.
Who it's for
Singles, couples and busy families who cook breakfast, snacks and dinners in the microwave will use the sensor and auto programs. Buyers who want extended coverage or a stripped-down basic model should look elsewhere.
Pros and cons
- Inverter delivers constant cooking power
- Genius Sensor automates timing
- Many auto cook programs
- Child safety lock
- Short manufacturer warranty
- Not smart home compatible
- Two different wattage figures confuse
Performance notes
The sensor measures steam released during cooking and tells the processor how much time remains at the right power, so results depend on food that releases steam normally. Inverter control holds a steady power instead of cycling, which helps edges and centers finish at the same time and gives gentler defrosting.
