Cosori TurboBlaze vs Ninja AF141: Bigger Basket or Faster Cook?

This is the first fork in the road. Cosori rates the TurboBlaze at 6 quarts for three to five servings; Ninja rates the AF141 at 5 quarts, enough for up to 4 lb of fries or 5 lb of wings by its count. RTINGS measured 6.3 and 5.1 quarts and found 75.5 against 64.9 square inches of floor in the basket, which is the number that decides how much food fits in a single layer. Consumer Reports measured the Ninja's usable space at only 3.8 quarts, so the gap in practice may be wider than the labels suggest.

RTINGS sizes the Cosori for about three to four people and the Ninja for two to three. It also notes that both baskets are only about 3.4 inches tall inside, so neither is a good fit for whole potatoes or tall buns.

The Ninja pays you back on the counter. Ninja lists it at 10.55 inches tall and 10.67 lb; Cosori lists the TurboBlaze at 11.9 inches and 13.2 lb. Tom's Guide says the Ninja slots under any upper cabinet, which matters if the air fryer lives below a low cabinet rather than in the open.

The Cosori is the better fryer in RTINGS's measured tests. Its fry test left 81.2 percent of a batch crispy, with 9.4 percent undercooked; the Ninja managed 71.9 percent crispy with 18.8 percent undercooked. With wings, 46.2 percent came out crisp on both sides in the Cosori against 35.0 percent in the Ninja. RTINGS scores the Cosori 8.2 for air frying overall against 7.5 for the Ninja, and its comparison concludes that the Cosori comes out ahead for most people because food cooks more evenly.

The other testers point the same way on evenness. TechGearLab ranked the Cosori second of ten and called its fries and tater tots exceptional, with salmon reaching 145°F inside in about 10 minutes after preheating. Tom's Guide found the Ninja's fries near the edge of the basket cooked faster than those in the center, and RTINGS saw more underbrowned, rubbery wings from it.

Tom's Guide still names the Ninja its best air fryer overall in a guide updated in June 2026, citing its simple controls and power, while the Cosori sits in that guide's also-tested section. The disagreement is less about results than about what each reviewer weighs: Tom's Guide values a compact, easy machine, and RTINGS weighs how much of each batch comes out right.

Here the Ninja wins clearly. RTINGS timed it reaching 400°F in 2 minutes 17 seconds, against 3 minutes 2 seconds for the Cosori, and it recovered in 2 minutes 39 seconds after cold food went in, against 3 minutes 50 seconds. Fries hit RTINGS's moisture-loss benchmark in 12 minutes 55 seconds in the Ninja and 13 minutes 46 seconds in the Cosori, and wings got there about three minutes sooner in the Ninja. Tom's Guide found a full basket of vegetables it had set for 40 minutes at 340°F done in the Ninja after 28, and sweet potato fries slightly overdone at the package time, so check food early.

The Ninja also holds its temperature more tightly. RTINGS measured a 14°F swing at a 400°F setting for the Ninja and 42°F for the Cosori, which it says makes the Ninja easier for recipes that need steady heat, such as salmon or thick pork chops. TechGearLab's numbers for the Cosori fill in the picture: over 20 minutes at 400°F it averaged 395.7°F, about 4°F low. In other words, the Cosori lands close to its setting on average but cycles more around it.

The Cosori has a preheat program, which Tom's Guide timed at 4 minutes, and RTINGS notes it tells you when preheating is done. The Ninja has no preheat step or reminder. Neither has a shake reminder, according to Tom's Guide.

The Cosori is the more versatile machine. Cosori lists a 90 to 450°F range and nine functions, including proof, bake, broil and keep warm. Ninja lists four functions (air fry, roast, reheat, dehydrate) and a top temperature of 400°F; its product page does not give the lowest setting. RTINGS measured the Cosori's fan from 1,000 to 3,600 RPM and the Ninja's from 1,420 to 3,000 RPM, and scores the Cosori higher for baking, dehydrating and broiling.

One detail: Cosori says its five fan speeds are tied to the cooking functions rather than set by hand, so the slow fan for dehydrating or proofing comes with the matching preset.

Both baskets and crisper plates are dishwasher safe, per Cosori for the TurboBlaze and per Consumer Reports and Tom's Guide for the Ninja. Tom's Guide found both easy to clean by hand. Both crisper plates lift out; Tom's Guide used the bare Ninja drawer for saucy food.

Coatings need a careful read. Cosori describes the TurboBlaze's basket and plate as PFAS-free ceramic, but TechGearLab listed PTFE in the cooking surface of the unit it bought, and RTINGS lists a PTFE crisper plate with a ceramic basket. Ninja calls its parts nonstick, and RTINGS lists the opposite split: a ceramic crisper plate and a PTFE basket. By RTINGS's account, neither is free of PTFE throughout.

Noise figures are not like-for-like. Tom's Guide measured the Cosori at about 68 dB with a phone meter at the top fan speed and 446°F, and its Ninja review lists 72 dB without describing the test. That suggests the Cosori is no louder, but the gap is too small and the methods too different to call.

Cosori backs the TurboBlaze with a two-year limited warranty; Ninja gives the AF141 one year.

Buy the Cosori TurboBlaze if you regularly cook for three or more, if crisp, even batches of fries and wings matter most, or if you want to proof dough, dehydrate or broil. It is the best overall pick on our air fryer list for those reasons, and the longer warranty is a bonus. Accept a slower preheat, more temperature cycling and a taller, heavier body.

Buy the Ninja AF141 if you cook for one to three people, have a low cabinet or a small counter, and want food done fast with steady heat and no extra settings. It is our budget pick. Accept a smaller usable basket, a 400°F ceiling, slightly less even batches and a one-year warranty.

If you want two foods finished at once, neither fits; see the dual-zone pick on the air fryer list.

Is Cosori or Ninja better?

For most households, RTINGS says the Cosori TurboBlaze, because its batches of fries and wings came out more evenly crisp and it offers a wider temperature and fan range. Tom's Guide prefers the Ninja AF141 as a compact, simple everyday fryer, and the Ninja heats faster and holds temperature more steadily in RTINGS's tests.

Which air fryer is bigger, the Cosori TurboBlaze or the Ninja AF141?

The Cosori. RTINGS measured 6.3 quarts and 75.5 square inches of cooking surface against 5.1 quarts and 64.9 square inches for the Ninja, and Consumer Reports measured only 3.8 usable quarts in the Ninja. The Ninja is the smaller appliance, at 10.55 inches tall and 10.67 lb.

Which air fryer is quieter?

Tom's Guide measured the Cosori at about 68 dB at its top fan speed and 446°F and lists 72 dB for the Ninja. The two figures were not taken the same way, so treat the difference as small.

Which is faster, Cosori or Ninja?

The Ninja. RTINGS timed it reaching 400°F in 2 minutes 17 seconds against 3 minutes 2 seconds for the Cosori, and it recovered faster after food went in.

Does the Ninja AF141 have a longer warranty than the Cosori?

No. Cosori covers the TurboBlaze for two years and Ninja covers the AF141 for one year, both as limited warranties.
