What to Look For When Buying an Air Fryer
Before diving into each model, here are the six criteria that matter most:
- Capacity vs. your household size: 4 quarts covers 1–2 people comfortably. 5–6 quarts handles families of 3–5. Buying too small means batching every meal; buying too large wastes counter space and energy.
- Wattage and preheat speed: Higher wattage (1,700W+) preheats faster and recovers temperature better when you open the basket mid-cook. For daily use, this adds up to meaningful time savings.
- Basket shape: Square baskets fit more food than round baskets of the same stated quart capacity — food lies flat and doesn’t curl at the edges. Worth prioritizing if you cook flat cuts like fish fillets or chicken breasts.
- Preset functions: Presets handle time and temperature for specific foods automatically. More presets reduce guesswork, especially for new air fryer users. Power users often ignore presets anyway.
- Coating type and durability: Ceramic coatings are more scratch-resistant than PTFE-based non-stick. Both degrade with harsh abrasives — always use silicone or plastic utensils.
- Noise level: Air fryers are not quiet appliances. The difference between 68 dB (Cosori) and 72 dB (Ninja) is noticeable in open kitchens or apartments — roughly the difference between a normal conversation and a busy restaurant.
Ninja AF101 4-Quart Air Fryer — Full Review
Specs
- Capacity: 4 quarts (fits ~2 lbs of fries, 2 chicken breasts)
- Wattage: 1,550W
- Temperature range: 105°F–400°F
- Functions: Air Fry, Roast, Reheat, Dehydrate
- Basket: Round, ceramic-coated crisper plate, dishwasher-safe
- Dimensions: 13 × 11 × 14 inches | Weight: 10 lbs
- Warranty: 1 year limited
- Amazon rating: 4.7/5 from 50,000+ verified reviews
Pros
- Outstanding user satisfaction: A 4.7-star rating across tens of thousands of reviews is one of the strongest in any kitchen appliance category. Repeat purchasers and gift-givers consistently praise reliability and consistency.
- Wide dehydrate temperature range: The 105°F floor is unusually low for an air fryer, making the dehydrate function genuinely effective for jerky, dried herbs, and fruit chips — not just a marketing checkbox.
- Compact and lightweight: At 10 lbs with a round basket footprint, the AF101 fits under most cabinets, stores in a lower cupboard without effort, and works well in small apartments or RVs.
- Ceramic basket coating: More durable than standard PTFE coatings. Resists scratching better and doesn’t flake under normal daily use.
- Dead-simple controls: Four buttons and a digital display. No app pairing, no Wi-Fi setup, no learning curve.
Cons
- 4-quart capacity is limiting for families: You cannot fit a whole chicken or more than two servings of most proteins without batching.
- No smart features: No app control, no Wi-Fi, no voice assistant compatibility.
- Only 4 presets: Cosori offers 13 one-touch cooking modes by comparison.
- Louder at ~72 dB: Clearly audible in quiet kitchens — similar to a loud conversation.
Who It’s For
The Ninja AF101 is the right pick for singles, couples, and anyone cooking for 1–2 people. It is also the best air fryer for anyone who wants maximum simplicity, limited counter space, or who specifically wants to dehydrate food at low temperatures. If you’ve never owned an air fryer and want to start without a complex setup, this is the easiest entry point on the market.
Cosori Pro Gen 2 5.8-Quart Air Fryer — Full Review
Specs
- Capacity: 5.8 quarts square basket (fits a whole 5 lb chicken)
- Wattage: 1,700W
- Temperature range: 170°F–400°F
- Functions: 13 presets — Steak, Chicken, Seafood, Shrimp, Frozen Foods, French Fries, Bacon, Vegetables, Toast, Bake, Preheat, Keep Warm, and custom
- Smart features: VeSync app (iOS/Android), Amazon Alexa, Google Assistant
- Basket: Square, non-stick, detachable liner, dishwasher-safe
- Dimensions: 11.8 × 11.8 × 12.6 inches | Weight: 16.7 lbs
- Warranty: 1 year limited
- Amazon rating: 4.4/5
Pros
- Large square basket holds more real food: A 5.8-quart square basket fits significantly more food than a 4-quart round basket of the same stated capacity. Chicken breasts lay flat without overlapping, fish fillets don’t curl.
- 13 one-touch presets eliminate guesswork: Dedicated buttons for bacon, seafood, and frozen foods mean the machine auto-selects the right time and temperature. Ideal for households with multiple cooks at different skill levels.
- Quieter operation at ~68 dB: Four decibels less than Ninja is a meaningful difference in open kitchens — closer to a normal conversation than a restaurant setting.
- VeSync app with 1,100+ recipes: Start and monitor cooking remotely, access a tested recipe library, and integrate with Alexa or Google Assistant for voice commands.
- Faster preheat from 1,700W motor: Heats up roughly 15–20% faster than the AF101. Over time, this matters when you’re cooking multiple meals per day.
Cons
- Heavier and bulkier: At 16.7 lbs with a square footprint, this is harder to store and move for cleaning.
- No low-temperature dehydrate mode: The 170°F minimum is too hot to properly dehydrate food.
- Slightly lower satisfaction rating: 4.4 stars versus Ninja’s 4.7. Some long-term reviewers report basket coating degradation after 12–18 months of heavy daily use.
- App dependency adds friction: The VeSync app adds value but also adds a setup step. Users who just want to press a button may find smart features more trouble than benefit.
Who It’s For
The Cosori Pro Gen 2 is built for families of 3–5, meal preppers, and smart-home enthusiasts. If you cook batch meals on weekends, regularly cook large cuts of protein, or want app-based control and recipe libraries, this is the more capable daily driver for a full household.
Head-to-Head Verdict
Cooking Performance
Both air fryers produce genuinely crispy results. Cosori’s square basket promotes slightly more even heat distribution because food lies flat without curling at the edges. Ninja’s ceramic-coated plate browns chicken skin more aggressively at max temp — useful for those who want maximum crispiness. For everyday meals — fries, wings, vegetables, reheated pizza — either machine delivers identical quality. Edge: Cosori for consistency; Ninja for maximum browning.
Ease of Use
Ninja wins clearly. Four buttons and a dial versus 13 presets and an app. For weeknight cooks who just want to press “air fry” and walk away, Ninja is faster to operate. Cosori’s presets are useful but require deciding which preset applies to your food — a small but real cognitive load. Edge: Ninja.
Cleaning
Both baskets are dishwasher-safe. Ninja’s ceramic crisper plate is easier to wipe clean by hand and harder to scratch than Cosori’s non-stick liner. Cosori’s detachable basket gives better access to corners for manual scrubbing. Overall: tie — ceramic coating vs. detachable design.
Value for Money
Ninja AF101 costs about $10 less than Cosori Pro Gen 2, but delivers 45% less basket capacity. On a per-quart basis, Cosori offers better value for larger households. For 1–2 person households, Ninja’s lower price and higher rating make it the smarter buy. Edge: Ninja for small households; Cosori for families.
Best for Families vs. Singles
- 1–2 people: Ninja AF101 — simpler, lighter, cheaper, higher rated.
- 3–5 people: Cosori Pro Gen 2 — bigger basket, faster preheat, more versatile presets.
Frequently Asked Questions
Is Ninja or Cosori better?
Neither is universally better — it depends on household size. Ninja wins for 1–2 people: higher satisfaction rating (4.7 vs. 4.4), simpler operation, lighter build, and lower price. Cosori wins for families: 45% more capacity, 13 presets, smart app features, and quieter operation. Match the machine to your cooking volume and you can’t go wrong with either.
Which air fryer lasts longer, Ninja or Cosori?
Both brands offer 1-year warranties. Ninja’s ceramic basket coating holds up better under heavy daily use than Cosori’s standard non-stick liner, based on long-term user reviews. With hand washing and silicone utensils, either appliance should last 3–5 years without significant coating degradation.
Can a Cosori air fryer cook a whole chicken?
Yes — the Cosori Pro Gen 2’s 5.8-quart square basket fits a whole 5-lb chicken. The Ninja AF101 at 4 quarts cannot accommodate a whole bird. This is one of the clearest practical differences between the two models.
Does Cosori or Ninja preheat faster?
Cosori’s 1,700W motor preheats slightly faster than Ninja’s 1,550W — roughly 1–2 minutes faster depending on target temperature. Both preheat dramatically faster than a conventional oven. In daily use, the difference between the two air fryers is minor.
Is Ninja AF101 good for dehydrating food?
Yes — it’s one of the AF101’s best differentiating features. The 105°F minimum temperature is low enough to properly dehydrate jerky, fruit slices, herbs, and vegetables. The Cosori Pro Gen 2 starts at 170°F, which is too hot for proper food dehydration. If you plan to make dried snacks regularly, Ninja is the better choice.
Conclusion: Which Air Fryer Should You Buy?
After comparing both machines across capacity, performance, ease of use, and value, the recommendation is clear:
- Buy the Ninja AF101 if you cook for 1–2 people, want the simplest possible air fryer experience, need a low-temperature dehydrate function, or are optimizing for counter space and budget. Its 4.7-star rating from over 50,000 verified buyers is one of the strongest endorsements in the air fryer category.
- Buy the Cosori Pro Gen 2 if you cook for 3 or more people, want smart app control and voice assistant compatibility, regularly cook large cuts of protein, or value quieter operation. The 5.8-quart square basket and 13 presets make it the more capable machine for full-household daily cooking.
Both are excellent air fryers from brands with proven track records. The only mistake is buying the wrong size for your household.
