THE SHORT ANSWER

Our take

Panasonic NN-SU656B is a black, 1.3-cu.-ft. countertop microwave with 1,100-W output, Genius sensor cooking and a 12.4-inch turntable. Its documentation also gives 1,500-W consumption and 120 V / 60 Hz. Seven auto-cook menus, ten power levels and a child lock distinguish it from very basic compact ovens. The model is microwave-only and has no established trim-kit route. The historical ASIN failed current identity checking, so shop by the tagged exact-model search and verify the B suffix.

Consider it for

Choose the NN-SU656B when a 1.3-cu.-ft. cavity, black variant and documented sensor programs are useful. Its 12.4-inch tray provides a concrete dish-fit check, while the 20.44 × 12.38 × 16.13-inch exterior helps with counter planning. The 1,500-W input figure is distinct from 1,100-W cooking output. The old ASIN is not verified; confirm the exact B code and seller's condition through a tagged model search. It has no documented built-in trim route or convection function..

Look elsewhere if

Choose another unit for convection, air-fry, built-in trim installation or a confirmed link to B01F2Y2LZ0. Select the W suffix only if white is the required version.

Pros & cons

What could work for you, and what to consider before buying.

What works in its favor

  • Genius sensor cooking and seven automatic menus are documented.
  • A 12.4-in. tray, 1.3-cu.-ft. cavity and 1,100-W output give buyers concrete size and power facts.
  • The exact black B variant has a documented U.S. supply and child lock.

What to weigh up

  • No convection or trim-kit route is documented.
  • The historical ASIN is not verified against the exact B model.
  • The 1,500-W consumption figure needs to be considered separately from 1,100-W output.

What the features mean for you

What does the sensor feature change?

Panasonic lists Genius sensor cooking and seven auto-cook menus for NN-SU656B. That makes it meaningfully different from a compact oven whose presets only run stored times. The manufacturer describes menu-specific cooking; this review does not claim that every food will finish perfectly or that the unit has been personally tested. Buyers who regularly reheat varied portions may prefer sensor-assisted programs, while a user who always enters a time manually may get less value from them.

How much room does the 1.3-cu.-ft. cavity provide?

The documented 1.3-cu.-ft. volume and 12.4-inch turntable make this a mid-size household model rather than a tiny dorm oven. The tray diameter gives a practical first check for plates; also check dish height and handles. Outside dimensions are about 20.44 inches wide, 12.38 high and 16.13 deep. Leave the required airflow and space for the push-open door, then compare those numbers with the counter rather than assuming capacity alone guarantees a fit.

Why are output and input listed separately?

Panasonic identifies 1,100 W as microwave output and 1,500 W as consumption. Output is the cooking rating, while consumption describes the appliance's electrical draw. The manual also specifies a 120-V/60-Hz supply. Do not use the smaller output number to size a branch circuit or treat the larger input as cooking power. Check the exact rating plate and circuit requirements at the planned location, particularly if the kitchen already shares a heavily loaded circuit.

What is the exact model and finish?

The B code is the black NN-SU656B variant. Panasonic separately identifies the white NN-SU656W, which shares much of the line but is not the same finish identity. Read the exact code on the seller offer and the appliance label; a cropped product photo or generic NN-SU656 title may omit the suffix. Historical ASIN B01F2Y2LZ0 did not resolve to the exact current offer, so the article uses a model search instead of relying on that old identifier.

Is this a built-in or combination microwave?

The reviewed product pages describe NN-SU656B as a countertop microwave. They do not establish a trim-kit installation, convection heating, broiling or air frying. A cabinet opening or desire for crisping therefore points toward another product type. This distinction is especially important because product titles often use broad phrases like microwave oven without clarifying how it installs or which heating elements it has. Follow Panasonic's exact placement instructions and do not adapt a trim kit from another code.

When is it a better choice than a smaller model?

Compared with Haier MWM0701TW, this Panasonic has a larger cavity, a 12.4-inch rather than 9.6-inch documented tray, higher output and sensor cooking. The Haier is more compact and gives a clearer 0.7-cu.-ft. footprint. Compared with Magic Chef MCM1310ST, the Panasonic has a published output and sensor feature, while the Magic Chef's exact wattage is unknown. Choose according to the need for sensing, verified tray fit and counter space rather than treating the names as a quality ranking.

What else to compare

Haier MWM0701TW is smaller at 0.7 cu. ft. and 700 W with a 9.6-in. tray. Magic Chef MCM1310ST offers 1.3 cu. ft. but its wattage is unresolved. Panasonic NN-SU656B is the choice here for verified sensor cooking and higher documented output.
