Panasonic HomeCHEF NN-CD87KS 4-in-1 vs Toshiba EC042A5C-BS 1.5 cu ft Convection

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Panasonic HomeCHEF NN-CD87KS 4-in-1 comes out ahead by a narrow margin (4.6 vs 4.3). The gap is mostly about Multi-mode cooks who want microwave, convection, broil, and air fry in one countertop appliance and value inverter-smooth power control. — read the strengths below before deciding.

Panasonic's HomeCHEF combines an inverter microwave, a true 100-425 degrees Fahrenheit convection oven, a FlashXpress broiler, and an air fryer in a 1.2 cu ft countertop footprint. It is the most mode-rich combination unit on the market at this price, and the inverter element lets it simmer and melt without the on-off cycling that defines lesser microwaves. The fan-noise and learning-curve complaints are real but manageable.

Strengths
  • Inverter microwave delivers smooth, low-power simmer that conventional magnetron units cannot replicate at sub-30% settings
  • Convection bake range from 100 to 425 degrees Fahrenheit covers proofing dough through full roasts in a 1.2 cu ft cavity
  • FlashXpress broiler reaches working heat in seconds without preheat, saving meaningful time over the convection element
Watch-outs
  • Cooling fan runs for up to six minutes after a cooking cycle ends and is audible across an open kitchen
  • Control panel layout has a real learning curve — first-week users routinely miss the combo-mode entry path
  • Heating evenness on plain reheats tested only mediocre at Consumer Reports despite the inverter design

Toshiba's EC042A5C-BS delivers the 1.5 cu ft convection cavity and 1000W microwave at roughly half the price of the Sharp SMC1585BS, with a wider 170-425 degrees Fahrenheit convection range that supports yeast-dough proofing. Consumer Reports rated it 'very good' on heating and 'excellent' on defrost, and the Smart Sensor handles common reheat tasks without manual entry. Skip it only if you need dedicated air-fry — convection alone handles browning competently.

Strengths
  • 1.5 cu ft cavity at half the price of competing 1.5 cu ft convection units — best capacity-per-dollar in the category
  • Convection range from 170 to 425 degrees Fahrenheit covers proofing through full roasts
  • 1000W microwave is competitive with mid-tier dedicated countertop microwaves
Watch-outs
  • No dedicated air-fry mode — convection element handles browning but lacks the high-velocity airflow of dedicated air fryers
  • Cooling fan runs after convection cycles, adding to ambient kitchen noise
  • Stainless interior reflects light into the cavity in a way that makes visual monitoring of dark foods harder

How they stack up

Panasonic HomeCHEF NN-CD87KS 4-in-1

The NN-CD87KS is the deepest cooking-mode toolkit in this group — five modes versus the Breville BMO870's three and the Toshiba EC042A5C-BS's two. Where the Sharp SMC1585BS gives you more raw oven volume, the Panasonic gives you the inverter for delicate simmer work the Sharp cannot match. If you cook on multiple modes weekly, this is the pick.

Toshiba EC042A5C-BS 1.5 cu ft Convection

The EC042A5C-BS matches the Sharp SMC1585BS on cavity volume (1.5 cu ft) at roughly $220 less, and it pushes 100W more microwave power. It cannot match the Sharp's built-in trim-kit installability or the Panasonic NN-CD87KS's mode depth, but it covers the convection-and-microwave-in-one-box use case at the lowest price in this guide.
