Overview
With a 1.2 cubic foot interior and 1000 watts of output, the Toshiba EM131A5C-BS is a countertop microwave built around a smart humidity sensor and a hidden child-lock button in the door handle.
Owners who measured before buying describe the footprint, about 16 by 20.6 inches, as accurate to the listing, and several specifically chose it because the interior fits a full-size dinner plate, not just a small bowl. The sensor and preset menu functions are available, but at least one long-time owner admits to using only basic timed cooking at full power and ignoring the automated modes entirely. One reviewer went through a support process with Toshiba after a unit developed a problem, describing an initial runaround before the company replaced it.
- 1000 watt output, 1.2 cu ft interior
- Smart humidity sensor cooking
- Six preset menus, ten power levels
- 12.4-inch removable turntable
Who it's for
Suits anyone who wants a larger-capacity countertop microwave that fits a full dinner plate and values a child safety lock. Less suited to anyone who wants to quickly pause and reopen the door mid-cycle without extra steps.
What buyers say
From Amazon customer reviews.
Owners consistently praise the size (it fits a full dinner plate), heating speed, and quiet operation, describing it as a step up from prior microwaves they replaced. The door-lock-before-opening behavior draws mixed reaction: some like it, others turn it off in settings. One owner needed a warranty replacement after their original unit developed a fault, and reports the replacement works well.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits a full-size dinner plate
- Heats quickly compared to older units
- Quiet operation, minimal noise
- Hidden child-lock button in handle
- Door must be paused before opening mid-cycle
- Larger footprint than compact models
- At least one reported need for warranty replacement
Performance notes
At 1000 watts, this runs hotter than typical compact microwaves and heats a dinner plate evenly according to several owners comparing it against prior units. The smart sensor mode adjusts time and power automatically based on food humidity, though at least one long-term owner sticks to manual timed cooking at full power instead. The door has to be paused or canceled before it can be opened mid-cycle, a safety behavior some owners disable through the settings menu.
