How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one countertop appliance that fries, bakes, broils, toasts, warms and dehydrates in a big 27.5-quart cavity with simple knobs, choose Plum chef Multifunctional Convection Toaster; if you need a guided, preset-driven air fryer oven with a touch panel, a viewing window and an interior light so you can watch food as it cooks, choose Uten Air Fryer Oven.
• Uten Air Fryer Oven — biggest strength: A touch-control, 8-preset air fryer oven with a large glass viewing window and inner light, so you can see and steer the cook without opening the door.
• Uten Air Fryer Oven — biggest trade-off: Its 24L interior is smaller than the Plum chef's, and the 39-pound body is heavy for a countertop appliance you might want to move around.
• Plum chef Multifunctional Convection Toaster — biggest strength: A 27.5-quart, 6-in-1 cavity that fits a whole 4.5lb chicken or six slices of toast and lets you cook three layers at once.
• Plum chef Multifunctional Convection Toaster — biggest trade-off: Knob controls are simple rather than precise, and there is no glass viewing window or interior light to monitor progress mid-cook.
• Who each pick is for: Uten for cooks who want preset programs and visual monitoring; Plum chef for families who want maximum capacity and multi-function flexibility from one appliance.
The Uten Air Fryer Oven is built around guided cooking. It pairs an 1800W heating system with eight preset functions and a temperature range that runs from Warm all the way up to 450°F, plus a 60-minute timer. That combination matters more than it sounds: if you are the kind of cook who wants to press a button for "air fry" or "bake" instead of guessing at time and temperature, the presets do the thinking for you. The touch control panel reinforces that — it is a modern, flat interface rather than a dial.
The feature I keep coming back to is the large glass viewing window paired with an inner oven light. Air frying is a visual process — you want to see how golden the fries or wings are getting without yanking the door open and dumping heat. Having a light inside means you can check progress in a dim kitchen at a glance. The 24L cavity is described as enough for a family-size meal for up to 10 people at once, and a drop-down door makes loading and unloading trays straightforward.
Build-wise, Uten uses brushed stainless steel on the outside and stainless steel for the inner tank, plus an enamel bakeware piece that the brand frames as easy to clean and hygienic. The exterior is metal, the door is stainless steel, and it is ETL listed for safety. It also claims to cut over 85% of fats versus traditional frying, which is the standard air-fryer pitch and worth taking at face value as a design goal rather than a guarantee.
Plum chef Multifunctional Convection Toaster: Who It's For
The Plum chef Multifunctional Convection Toaster takes the opposite approach: it goes wide instead of guided. Its headline is capacity — a 27.5-quart interior that the brand says fits a whole 4.5lb chicken or six slices of toast, with the included trays and racks letting you cook three layers of food at the same time. For a family or anyone cooking for a crowd, that vertical stacking is the real selling point. You are not running two batches; you are running one.
The second pillar is the 6-in-1 design. Plum chef positions it as a replacement for several appliances at once: air fryer, convection oven, toaster, broiler, food warmer and dehydrator. So the same box that air-fries crispy fries can bake a pizza, toast bread, grill a steak, or dehydrate snacks. If counter space is tight and you would rather own one appliance than four, that consolidation is the argument. The rapid air circulation technology is credited with up to 85% less oil than deep frying — again, a design claim about method, not a promise about your specific recipe.
Controls are deliberately simple: knob control for function and temperature, with adjustable temp and time. That is a genuine advantage for anyone who finds touch panels fussy or who wants to twist a dial with wet hands. The trade-off is granularity — knobs are less precise than a digital readout, and there is no viewing window or interior light listed, so you will be opening the door to check doneness.
It is also notably lighter at 15.6 pounds, with a stainless steel front and a non-stick interior that wipes clean. The compact countertop footprint (about 16.5" L x 15.9" H, and 15.16"D x 15.94"W x 14.57"H overall) is described as space-saving despite the large cavity. Included: a mesh rack, a retrieval clip and a baking pan.
Who should buy it: families, batch cooks, and anyone who wants one appliance to do many jobs with dead-simple controls. Who should skip it: cooks who want preset programs, precise digital temperature entry, or a window to watch food cook.
Side-by-Side: Which Should You Choose?
• Best for guided, preset cooking → Uten Air Fryer Oven. Eight presets and a touch panel remove the guesswork.
• Best for watching food as it cooks → Uten Air Fryer Oven. The glass viewing window and inner light are features the Plum chef listing does not include.
• Best for replacing multiple appliances → Plum chef Multifunctional Convection Toaster. The 6-in-1 design explicitly covers air fryer, convection oven, toaster, broiler, warmer and dehydrator.
• Best for simple, no-menu controls → Plum chef Multifunctional Convection Toaster. Knob control is intuitive and forgiving.
• Best for precise temperature control → Uten Air Fryer Oven. A digital touch interface with a Warm-to-450°F range and 60-minute timer gives finer control.
• Best for easy moving and storage → Plum chef Multifunctional Convection Toaster. At 15.6 pounds it is far lighter than the Uten's 39 pounds.
• Best for cooking a whole chicken or six slices of toast at once → Plum chef Multifunctional Convection Toaster. Both are listed as fitting inside its cavity.
In my opinion, I would buy the Plum chef Multifunctional Convection Toaster. The 27.5-quart capacity, three-layer cooking, and 6-in-1 flexibility cover more real weeknight scenarios — a whole chicken, a full tray of wings, toast in the morning, dehydrated snacks on the weekend — and the 15.6-pound body is far easier to live with on a counter. The Uten is the better pick if presets and a viewing window matter more to you than sheer volume, and its touch panel and interior light are genuinely nice touches. But for most families who want one appliance to do the most, I would go Plum chef.
