More from this brandAll Panasonic countertop microwave ovensOverview
The Panasonic NN-SN66KB is a 1.2 cu ft countertop microwave with Genius Sensor cooking and Inverter Technology, measured by one buyer at 1200W of actual output, in a black finish sized for mid-size kitchens.
Inverter technology is Panasonic's mechanism for delivering steady power at partial settings instead of cycling full power on and off, which is what buyers usually notice as more even reheating.
- 1.2 cu ft capacity
- Inverter Technology for steady power
- Genius Sensor cooking
- 1200W output per buyer measurement
Who it's for
Kitchens that want a mid-size microwave with more consistent power at lower settings than a basic cycling model. Less ideal if you specifically need backlit controls for use in dim rooms.
Pros and cons
- More powerful than typical 1000W microwaves per reviewer testing
- Genius Sensor and Inverter Technology for even cooking
- Fits well in mid-size kitchen spaces
- Straightforward to set up and use
- Controls are not backlit, hard to see in dim light
- End-of-cycle beeping is loud with multiple beeps
- At least one buyer received a refurbished unit despite ordering new
- LED digits described as too close together to read easily
Performance notes
One reviewer measured it delivering more power than typical 1000W microwaves and attributed the difference to its 1200W rating. Inverter technology maintains steady output at partial power settings rather than pulsing full power, which several buyers connect to more even results.
