Product listings provide exact external dimensions for each model (examples range from compact units around 10.1 x 5.7 x 5.7 inches to larger oven footprints near 21.77 x 15.67 inches). Look for notes about space-saving designs—some models include fold-in or collapsible features to reduce cabinet or counter footprint.
Common features include large viewing windows and interior lights for easy checks, French-style doors or transparent baskets for visibility, and handling aids like single-pull doors, splash guards that double as lids, or ergonomic handles.
Countertop ovens and air fryers commonly offer functions such as air fry, toast, bake, broil, roast and dehydrate; some larger units also include rotisserie. Prep appliances (choppers and blenders) list chopping/mincing, puréeing/blending and ice-crushing.
Wattages in this selection run from small prep units around 200 W up to high-power appliances between 1,000 W and 1,700 W (examples include 1,000; 1,250; 1,500; 1,550; and 1,700 watts).
Typical accessories include air-fry baskets, oven racks, baking pans and crumb trays. Some multifunction ovens add rotisserie spits, extra air-fry baskets and a drip tray. Blenders may include tamper tools and glass pitchers, and many units also include a user manual and recipe book.
Many models offer one-touch cooking presets—typically about 10 to 14 functions—as well as guided cooking prompts (sometimes labeled Guided Cooking). Other helpful features include Preheat and Turn Food reminders and intuitive digital touch controls or touchscreens.
