The Panasonic NN-SD691S is a 1.1 cu. ft. household inverter microwave rated for 1,200 W cooking power. Panasonic’s documents establish its dimensions, electrical specifications and advertised functions, but they do not establish real-world heating performance, reliability or current value. If you are considering a used or remaining-stock unit, check the fit and condition directly; present-day availability and price have not been verified.
What the NN-SD691S specifications tell you
Panasonic lists the NN-SD691S at 1.1 cu. ft. capacity. A separate Panasonic Canada specification sheet gives 1,200 W cooking power, 1,480 W power consumption, 120 V / 60 Hz electrical supply and a 2,450 MHz operating frequency. Cooking power and power consumption describe different things: 1,480 W is not the microwave’s cooking output.

Will it fit on your counter?
Panasonic lists exterior dimensions of 20 11/16 × 12 1/4 × 15 13/16 inches (525 × 310 × 401 mm), and cavity dimensions of 13 15/16 × 9 15/16 × 14 3/8 inches (355 × 251 × 365 mm). Use the exterior measurements to assess the appliance’s footprint, not the cavity dimensions, and leave the clearances specified in the manual. The manual’s installation guidance is the relevant reference for placement; do not assume that a countertop model is suitable for built-in installation.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Before buying, measure the counter and the available height and depth around it, then compare those measurements with the manual’s installation requirements. The manufacturer’s dimension chart also lists the NN-SD698 and NN-SD69LS at 1.2 cu. ft.; that larger listed capacity alone does not show which model will fit your dishes or space better.
Which cooking features are documented?
The operating manual documents inverter operation, sensor cook and reheat, turbo defrost, melt-and-soften, keep-warm, and manual power-and-time programming. These are listed functions, not independent evidence of speed, heating evenness or food results.

Manual power and time programming
Panasonic’s support guidance says manual cooking can be programmed in up to three stages. See Panasonic’s manual programming instructions for the control sequence. The model’s 2011 operating instruction and cook book covers the appliance’s controls, cooking functions and safety guidance.
What this review can—and cannot—establish
Panasonic’s documentation supports a specifications-and-features assessment, not a hands-on performance review. It does not establish how evenly or quickly this particular unit heats food, how noisy it is, how durable it will be, or what repairs it may need. Condition matters especially when considering a used appliance, so inspect the specific unit and test its controls and operation before committing where possible.

The manual is dated 2011. Its existence confirms the model and provides operating guidance, but it does not establish current stock, price, warranty coverage, or replacement-parts availability. Verify those details for the particular seller and location. No compatible replacement tray or other part is established here, so check a manufacturer part number or confirmed compatibility before ordering.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Who should consider the NN-SD691S?
It may suit someone seeking a 1.1 cu. ft. countertop microwave with documented sensor and inverter features, provided its footprint and electrical requirements work for their kitchen. For a used or remaining-stock unit, prioritize physical condition, fit, seller terms and any applicable warranty over the feature list alone. If comparing it with another microwave, assess cavity capacity, outside dimensions, cooking output, controls and installation clearances together rather than using capacity or wattage as a standalone verdict.
