An air fryer toaster oven combines several appliances into one countertop unit — toast, bake, broil, and air fry without heating up a full-size oven. We compared three popular options: the Cuisinart TOA-70NAS, the BLACK+DECKER 6-Slice, and the BLACK+DECKER 4-Slice.
The Cuisinart leans into versatility and capacity. Both BLACK+DECKER models are built for price and footprint, at two different sizes.
A safety note before anything else: with any air fryer or toaster oven, oil splatter onto an exposed heating element is a known fire risk — not unique to one brand or model. Keep oil and food clear of the heating coil, don’t overfill the basket, and don’t leave the appliance unattended while air frying. We flag a specific incident report under the 4-Slice model below, but the underlying precaution applies to all three.
A note on sourcing: specs and pricing below have been checked against current manufacturer and retailer listings (Amazon, Walmart, Cuisinart, Lowe’s) as of August 2026. Performance and reliability claims are drawn from customer review patterns rather than independent lab testing — treat those as directional feedback, not verified benchmarks.

Specifications and prices change over time and by retailer — confirm current listings before buying. The 4-Slice’s wattage isn’t published on Amazon, Walmart, Target, or BLACK+DECKER’s own site as of this writing; we’re noting that gap rather than estimating a number we can’t verify.
1. Cuisinart TOA-70NAS — Best Overall
The most versatile of the three: 1,800W, eight cooking functions (air fry, toast, convection bake, bake, convection broil, broil, grill, warm), and a 0.6-cubic-foot interior with a 3-pound air-fry capacity, big enough for a 12-inch pizza or a 4-pound chicken. It measures roughly 15.75″ wide by 12.25″ deep by 13.75″ high — check that against your counter and any upper cabinets before buying, since it’s the tallest of the three.
What reviewers like: even heating, fast cooking, easy cleanup, and simple mechanical dial controls — several reviewers specifically preferred the analog design after bad experiences with touchscreen ovens on other appliances.
What reviewers flag: a handful of longer-term owners report heating or broiling issues appearing after a couple of years. The mechanical timer ticks audibly, which bothers some users. It’s also taller than compact toaster ovens, so check clearance under your cabinets before buying.
Best for: households that want one appliance to replace multiple cooking modes, and don’t mind paying more for it.
2. BLACK+DECKER 6-Slice — Best Budget Large-Capacity
At roughly a third of the Cuisinart’s price, this model still fits six slices of bread or a 12-inch pizza in a 0.78-cubic-foot interior — actually larger by volume than the Cuisinart, despite the lower price and fewer functions. It runs at 1,500W (vs. the Cuisinart’s 1,800W), with five functions: air fry, bake, broil, toast, keep warm.
What reviewers like: strong results air-frying frozen foods (fries, nuggets, pizza) in the 15–20 minute range, an easy-to-clean removable crumb tray, and it’s a popular substitute for heating a full oven in warm climates.
What reviewers flag: inconsistent results — some report needing longer cook times or higher temps than expected for certain foods. There’s also recurring feedback about the door feeling flimsy and the exterior getting hot during use, plus at least one report of a faulty heating element. Quality control appears to vary more here than with the other two models.
Best for: buyers who want the Cuisinart’s capacity without its price, and don’t need convection or grill modes.
3. BLACK+DECKER 4-Slice — Best for Small Kitchens
The compact option: four slices of bread, a 9-inch pizza, same five functions as the 6-slice model in a smaller footprint. Good fit for apartments, dorms, or anyone tight on counter space.
What reviewers like: simplicity, fast heating, quiet operation, and easy cleaning. Several long-time BLACK+DECKER owners repurchased this model specifically for its familiar compact design. The air-fry function gets consistently positive marks for potatoes and fries.
What reviewers flag: the heating elements sit close to the food, so items can brown or burn faster than expected if unmonitored. The exterior runs hot during use. One reviewer reported a fire incident from oil splattering onto the heating element — this is a single reported case, not evidence the model is uniquely dangerous, but it’s a concrete reminder to follow the safety guidance at the top of this article: keep oil away from the element and don’t walk away while air frying, on this model or any other.
Best for: one or two people, small kitchens, and anyone prioritizing counter space over capacity.
Which One Should You Buy?
Priority | Pick |
Most cooking functions and capacity | Cuisinart TOA-70NAS |
Large capacity at a lower price | BLACK+DECKER 6-Slice |
Smallest footprint | BLACK+DECKER 4-Slice |
Simple mechanical controls (no digital interface) | Cuisinart TOA-70NAS |
Tightest budget | BLACK+DECKER 4-Slice |
Cooking for a family or batch meals | Cuisinart TOA-70NAS |
Cooking mostly for one person | BLACK+DECKER 4-Slice |
The Cuisinart is the strongest all-around pick if you want one appliance to handle real variety and don’t mind the price. The 6-Slice BLACK+DECKER gets you most of the capacity for a third of the cost, with a tradeoff in build consistency. The 4-Slice makes sense specifically for small-kitchen, small-portion use — not as a cheaper substitute for the 6-Slice if you actually need the extra room.
FAQ
Which is safest to use with oil for air frying? All three carry the same general risk profile — any exposed heating element and oil is a combination that requires care, regardless of brand. Use the amount of oil the recipe calls for, don’t overfill the basket, and monitor the appliance while it’s running, especially early in ownership before you know its habits.
Is the extra cost of the Cuisinart worth it? If you’ll use the additional modes (convection, grill, broil) regularly, yes — reviewers rate it highest of the three and it’s built for more varied cooking. If you mainly want toast and basic air frying, the 6-Slice BLACK+DECKER covers that at a much lower price.
Why choose the 4-Slice over the 6-Slice if they’re both BLACK+DECKER? Purely for space — the 4-Slice has a meaningfully smaller footprint and lower price, but also less capacity and a shorter 30-minute timer. If your kitchen can fit the 6-Slice, its extra capacity and 60-minute timer are worth the modest price difference for most people.
Do these replace a full-size oven? No — they’re built for small-batch cooking, reheating, and everyday meals, not large roasts or big batches of baking. All three are best thought of as a faster, lower-energy alternative for meals a full oven would be overkill for.
