The Australian-market Panasonic NN-ST671S is a 32 L, 1100 W, microwave-only inverter model with a 340 mm glass turntable. Panasonic’s published specifications document its size and controls, but they do not establish how it performs in independent cooking tests. CHOICE lists the model as discontinued, so check local stock, warranty terms and the appliance’s regional electrical rating before buying.
What the NN-ST671S offers
Panasonic Australia’s archived specification page lists this as a solo microwave, not a combination oven: it has no listed grill or convection function. Its headline specifications are:

How the controls and presets are specified
The archived Australian specification lists touch controls and an LCD display, plus sensor cooking and reheat functions. It specifies 14 one-touch sensor-cooking categories, ten variable power levels, More/Less control, Inverter Turbo Defrost and a child safety lock. These details describe the listed feature set; they do not show how accurately or consistently the presets cook particular foods.

- 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.
Panasonic describes inverter operation as a feature of the model, but the available specifications do not independently verify a cooking advantage. Do not assume menu counts or functions from newer Panasonic models apply to the NN-ST671S.
Will it fit on your bench or in a cabinet?
Countertop space
The stated outer dimensions are 525 mm wide, 310 mm high and 388 mm deep. Measure the shelf itself and consult the manual for required ventilation clearances; the appliance’s outer dimensions are not a recommended installation-opening size. Check the 340 mm turntable against the dishes you use, allowing room for the dish to rotate.

Built-in installation
The Australian manual lists the NN-TK611SS trim kit for the NN-ST671S. For that kit, it gives a cabinet opening of 562 × 395 × 480 mm (W × H × D) and trim-kit outside dimensions of 596 × 410 mm. Those are kit-specific installation figures, not the microwave’s countertop footprint. Confirm the exact kit, availability, fit and ventilation requirements against the manual before cutting or modifying cabinetry. The manufacturer’s Australian manual page is the reference for installation details.
Is the Panasonic NN-ST671S still worth buying?
It may suit someone who wants a large-capacity, turntable-based microwave with sensor presets and does not need grilling or convection. Whether it is a good purchase now depends on finding a suitable unit at a price and with warranty coverage you are comfortable with: CHOICE marks the model discontinued, which does not prove every seller has run out of stock. Check the seller’s current listing and written warranty terms rather than assuming availability or coverage from an old product page.

CHOICE’s surfaced page does not provide usable open test results for this model, and retailer ratings or individual owner comments are anecdotal rather than controlled performance evidence. This review therefore cannot establish cooking quality, noise, reliability or ease of cleaning. See CHOICE’s microwave listings for its model status.
Check the regional version before connecting it
This article’s specifications refer to the Australian-market model. Panasonic’s Australian manual states 230–240 V, 50 Hz, while a Panasonic North American manual groups the NN-ST671S with models specified for 120 V, 60 Hz. The shared model number does not make the electrical versions interchangeable. Before purchase or use, read the appliance nameplate and use the manual for that exact regional version; do not rely on a seller’s abbreviated listing alone. The regional manuals are available from Panasonic Australia and Panasonic North America.

Who should consider it?
- It may fit your needs if you want a 32 L microwave-only appliance, can accommodate its footprint and rotating 340 mm tray, and value the listed sensor and defrost controls.
- Compare current models first if you need a grill or convection oven, need a particular cabinet installation, or want independently documented performance results.
- Measure and verify before buying if you are considering a used or remaining-stock unit: confirm the regional voltage on the nameplate, test the door and controls in person where possible, and get the seller’s warranty and return terms in writing.
Newer related Panasonic models are separate products, not updated names for the NN-ST671S. For any alternative, compare its own manual, dimensions, output and current availability rather than carrying over this model’s menu or installation details.
