Design and build quality

The BLACK+DECKER EM031MB11 features a modern aesthetic with a stainless steel door frame and a black enclosure. Its dimensions are listed as 20.6 inches in length, 16.5 inches in width, and 11.8 inches in height. This unit includes a push-button door release mechanism for easy access during operation. In contrast, the Frigidaire EMW788RETRO focuses on a catchy retro look with a black finish. It utilizes an oversized knob for operation, which distinguishes it from standard digital interfaces. Both appliances are constructed for countertop use, though the BLACK+DECKER model provides specific exterior measurements while the Frigidaire emphasizes its internal capacity rating.

Power and cooking performance

Cooking speed and efficiency are largely determined by output wattage. The BLACK+DECKER model delivers 1000 watts of output power, allowing for faster heating and cooking times compared to lower wattage units. It also specifies an input power of 1600 watts. The Frigidaire unit operates at 700 watts, which is sufficient for reheating beverages or defrosting but may struggle with larger or denser food items. The 1000-watt output of the BLACK+DECKER provides 10 distinct power settings, giving users granular control over cooking intensity. The Frigidaire does not list specific power setting counts beyond its defrost capabilities.

Capacity and interior space

Internal volume dictates what size dishes can accommodate inside the microwave. The Frigidaire EMW788RETRO explicitly states a capacity of 0.7 cubic feet, categorizing it as a compact unit suitable for smaller kitchens or dormitories. The BLACK+DECKER EM031MB11 does not list a cubic foot capacity in the provided data but includes a removable 12.4-inch glass turntable. A turntable of this size suggests a interior footprint capable of handling dinner plates, aligning with its pre-programmed dinner plate button. Users needing to heat larger casseroles may find the BLACK+DECKER interior more accommodating based on the turntable diameter.

Control panel and usability

Interface design impacts how users interact with the appliance daily. The BLACK+DECKER features a large LED digital display with an easy-to-read control panel. It includes specific pre-programmed buttons for popcorn, potato, pizza, frozen vegetable, beverage, and dinner plate. Additionally, it offers 30 seconds express cooking for quick tasks. The Frigidaire relies on a retro themed oversized knob for control, which may appeal to users preferring mechanical inputs over digital menus. It includes speed and weight defrost functions. The digital interface of the BLACK+DECKER offers more specific cooking shortcuts compared to the knob-based system.

Safety features and locks

Safety mechanisms are critical in households with children or high traffic areas. Both microwaves include a child safety lock to prevent unauthorized operation. The BLACK+DECKER unit also features an interior light, allowing users to monitor food without opening the door and breaking the cooking cycle. The push-button door release on the BLACK+DECKER adds a layer of controlled access compared to traditional pull handles. The Frigidaire lists its child safety lock as a key feature but does not specify additional safety lighting or door mechanisms in the provided data. Both units meet basic safety standards for consumer countertop microwaves.

Energy efficiency and input

Energy consumption is indicated by input power ratings where available. The BLACK+DECKER EM031MB11 lists an input power of 1600 watts to achieve its 1000 watts of output. This ratio indicates the energy conversion efficiency of the magnetron and internal components. The Frigidaire model does not provide an input power specification in the available data. Users concerned with electrical load should note the 1600 watt input requirement for the BLACK+DECKER unit. Frequency for the BLACK+DECKER is listed at 60 Hz, which is standard for North American household outlets. The Frigidaire operates at 700 watts output, likely drawing less total power from the wall.

Price and value proposition

Cost is a significant factor for budget-conscious shoppers. The Frigidaire EMW788RETRO is priced at $79.99, making it the more affordable option between the two. The BLACK+DECKER EM031MB11 is listed at $132.99, reflecting its higher power output and additional digital features. Neither product currently displays user ratings or review counts in the provided data. The price difference of approximately $53 suggests the BLACK+DECKER is positioned as a mid-range option while the Frigidaire targets the entry-level market. Buyers must weigh the cost savings against the reduction in cooking power and features.

Which one should you buy?

Selection depends on individual kitchen needs and budget constraints. The BLACK+DECKER EM031MB11 is the recommended choice for users who prioritize cooking performance and versatility. Its 1000 watts of power and 10 power settings handle a wider variety of foods effectively. The digital presets and larger turntable add convenience for daily meal preparation. The Frigidaire EMW788RETRO is suitable for those seeking a specific retro aesthetic or a lower price point. Its 0.7 cubic foot capacity and 700 watts are adequate for basic reheating tasks. Ultimately, the BLACK+DECKER offers better long-term utility, while the Frigidaire offers immediate cost savings and style.
