Our take
Panasonic's owner manual covers NN-SN946B and NN-SN946W as separate variants and lists 1,250-W cooking output, separate 1,460-W/12.3-A consumption, 120 V/60 Hz, Inverter technology and Sensor Cook/Reheat. Its official dimension comparison lists the NN-SN946 family at 2.2 cu. ft.; an exact-model retailer specification identifies NN-SN946B as black with a 16.5-in. tray. The same-family manual marks it for household use, not commercial service. Panasonic's current U.S. trim finder says no kit is available, while an older exact-model spec lists trim-kit numbers; keep the installation tag unresolved. B01JPCS212 did not verify the offer, so the affiliate destination searches the exact model. This is specification-based analysis, not personal-use testing or a buyer-review summary.
Panasonic's official comparison lists 2.2 cu. ft. and exterior dimensions of 23 7/8 × 14 × 19 7/16 in.; the exact model spec gives a 16.5-in. tray. Allow for counter ventilation and dish rotation. The manual lists 120 V/60 Hz, 1,460-W/12.3-A consumption separate from 1,250-W output. Do not plan cabinet installation until Panasonic resolves the conflicting trim references..
Choose another model if you need commercial-duty service, a verified trim-kit route or a small footprint. Its 2.2-cu.-ft. cavity and 16.5-in. tray need substantial counter room, and the old ASIN is not proven.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Panasonic documentation gives 2.2 cu. ft. and 1,250-W output, with the 1,460-W/12.3-A electrical draw listed separately.
- Inverter, Sensor Cook, Sensor Reheat, Turbo Defrost, ten levels and child lock are documented for the exact B/W family.
- An exact-model retailer page confirms NN-SN946B as black and lists a 16.5-in. turntable.
What to weigh up
- The 2.2-cu.-ft. body and 16.5-in. tray demand more counter and dish clearance than compact models.
- Panasonic's current trim finder and older exact-model kit references disagree; cabinet compatibility remains unresolved.
- The manual specifies household use, and frozen ASIN B01JPCS212 did not verify a direct Amazon product mapping.
The key details
| Model covered | NN-SN946B |
|---|---|
| Capacity | Panasonic's manual names NN-SN946B and NN-SN946W separately; the exact-model retailer specification identifies NN-SN946B as black, while the source's B suffix is kept distinct from W. |
| Microwave output | Panasonic lists 2.2 cu. ft. and the manual specifies 1,250-W cooking output, separate 1,460-W/12.3-A consumption and 120-V/60-Hz supply. |
| Cooking approach | The combined manual documents Inverter, Sensor Cook, Sensor Reheat and Inverter Turbo Defrost; the model family has ten power levels and child lock. |
| Installation options | The exact-model specification lists a 16.5-in. turntable; Panasonic's official dimension table confirms the 2.2-cu.-ft. family size. |
| Finish and turntable | Panasonic's current trim finder says kits are unavailable for NN-SN946B/W, but an older exact-model specification lists trim-kit numbers. Preserve this conflict; trim-kit compatibility remains unconfirmed. The frozen B01JPCS212 ASIN failed; use an exact-model search. |

What the features mean for you
Keep NN-SN946B separate from NN-SN946W and nearby models
Panasonic's manual names NN-SN946B and NN-SN946W separately, while the exact-model retailer specification identifies B as black. Preserve that suffix-level distinction, and do not merge either with NN-SN936, NN-SN966 or NN-SN973 based on a shared 2.2-cu.-ft. size. The frozen source's B01JPCS212 ASIN failed, so exact model identity is supported by Panasonic documentation and the exact-model source record rather than a direct Amazon page.
Compare the 2.2-cu.-ft. cavity and 1,250-W output
Panasonic's official comparison lists NN-SN946 at 2.2 cu. ft. Its manual specifies 1,250 W cooking output and separately lists 1,460 W/12.3 A consumption at 120 V/60 Hz. Keep output distinct from wall draw when comparing cooking power and planning the electrical connection. These values answer different questions: cooking output is not electrical consumption or branch-circuit guidance.
Use the documented Inverter and sensor functions
The combined Panasonic manual documents Inverter operation, Sensor Cook, Sensor Reheat and Inverter Turbo Defrost for the NN-SN946 family. Follow its model-specific charts and container guidance. These are confirmed controls for the family; do not add any other menu feature without an exact source. Stay within the cited manual, particularly for sensor prompts and defrost containers.
Check dishes against the 16.5-inch turntable
The exact-model specification lists a 16.5-in. turntable. This supports a wider dish than a compact tray, but still requires checking the dish base and rotation clearance. Compare the actual cookware to the tray rather than assuming that all large cavity models accept the same platter.
Resolve the trim-kit source conflict before cabinet use
Panasonic's current U.S. trim finder says kits are unavailable for NN-SN946B/W, while an older exact-model specification lists 27- and 30-in. trim-kit numbers. Because those sources conflict, trim-kit compatibility remains unconfirmed. Treat the verified form as countertop and ask Panasonic to confirm the exact kit and installation manual before planning a built-in opening.
Respect household duty and use the exact-model search
Panasonic's owner manual specifies household use; do not match this model as a foodservice microwave. The old B01JPCS212 Amazon page failed, so the affiliate destination searches NN-SN946B and carries buyershortlists-20. It makes no claim about current stock, offer condition or customer ratings. Search results can include nearby B and W variants, so confirm the complete suffix on the offer.
What else to compare
For cabinet installation, select a Panasonic model with a current finder result and matching kit manual. For a smaller counter, compare a compact model's documented tray and case dimensions. NN-SN946B is defined by its 2.2-cu.-ft. capacity, 1,250-W output, Inverter and sensor controls, 16.5-in. tray, and household-use classification.
Before you buy
What are NN-SN946B's capacity and output?
Panasonic lists 2.2 cu. ft. and 1,250-W cooking output; the manual separately lists 1,460-W/12.3-A consumption.
Does NN-SN946B have sensor cooking?
Yes. Panasonic documents Sensor Cook and Sensor Reheat in the shared NN-SN946 manual.
How large is the turntable?
An exact-model specification lists a 16.5-in. turntable.
Is NN-SN946B black?
The exact-model retailer specification identifies NN-SN946B as black; Panasonic's manual separately lists the B and W suffix models.
Can I use a trim kit?
Panasonic's current finder says kits are unavailable, while an older exact-model specification lists kit numbers. The conflict is unresolved; confirm a compatible kit and installation guide with Panasonic.
Does B01JPCS212 directly match NN-SN946B?
The frozen page failed verification. Use the tagged exact-model Amazon search rather than a direct ASIN link.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
Panasonic NN-SN946B is a black 2.2-cu.-ft. countertop microwave with 1,250-W output, Inverter and Sensor Cook/Reheat; its manual lists 1,460-W/12.3-A input at 120 V/60 Hz and household-only use. The exact model specification gives a 16.5-in. tray. Panasonic's current trim finder conflicts with an older kit reference, so trim remains unknown. B01JPCS212 is unverified; use the tagged exact-model search.
