Detailed Review of Cosori Pro 3.7‑Quart Air Fryer
The Cosori Pro 3.7‑Quart Air Fryer is a compact, no‑frills workhorse that fits well in smaller kitchens or on crowded countertops. It uses a square basket and a 1500‑watt heating element to circulate hot air around food, giving you crispy fries, wings, and roasted vegetables without the mess of oil. The design is modern, with a dark plastic body and a front‑facing LED touchscreen that makes it easy to jump between presets.
In real‑world use, the 3.7‑quart basket is ideal for one or two people. You can cook a decent batch of fries, fish sticks, or small chicken wings, but you will likely need to cook in two rounds if you are serving a family of four.
The 11 built‑in presets cover air fry, bake, roast, toast, reheat, dehydrate, and keep warm, so you can quickly switch from crispy fries to reheating leftovers without fiddling with settings. The unit also includes a shake reminder and an automatic shut‑off for safety, which is helpful if you walk away from the kitchen while something is cooking.
Coffee‑shop style fries, frozen nuggets, and roasted vegetables come out well‑cooked but not overloaded. Because the basket is smaller, the hot air circulates more tightly, which can help certain foods get extra crispy. The basket itself is non‑stick, dishwasher‑safe, and easy to clean, and the air fryer is advertised as PFOA‑free and BPA‑free, which many health‑minded users appreciate.
Pros
- Compact 3.7‑quart basket that suits couples or singles without wasting energy.
- 1500‑watt motor cooks quickly for small portions and simple meals.
- 11 presets plus manual time and temperature control make it beginner‑friendly.
- Includes shake reminder, preheat, and keep‑warm functions for safer cooking.
- Non‑stick, dishwasher‑safe basket and BPA‑/PFOA‑free materials for easier cleaning.
Cons
- Too small for families; you will need to cook in multiple batches for 3–4 people.
- No app or smart features; you must use the physical controls only.
- Limited preset options compared with newer smart models that offer more modes.
- Slight smell during first uses, like many new plastic‑bodied fryers, can bother some users.
Detailed Review of Cosori Pro 5.8‑Quart Smart Air Fryer
The Cosori Pro 5.8‑Quart Smart Air Fryer is the bigger, more connected sibling in Cosori’s lineup. With a 5.8‑quart (5.5 L) square basket, it can handle meals for 3–5 people, making it a strong choice for families, meal preppers, or anyone who cooks bigger batches of frozen foods or whole chickens. The 1700‑watt motor gives it a bit more power than the 3.7‑quart model, which helps speed up cooking for larger loads.
A major difference is the smart functionality. This model connects to the VeSync app via Wi‑Fi, allowing you to start, stop, pause, and monitor cooking from your smartphone. You can schedule meals in advance, receive notifications when food is ready, and even use voice control with Alexa or Google Assistant on some versions.
The touchscreen shows 11–12 presets, depending on the exact variant, including air fry, bake, roast, toast, dehydrate, and keep warm. The wide temperature range (170–400°F) and adjustable timer (1–60 minutes) make it flexible for anything from reheating pizza to dehydrating fruit.
In daily life, the 5.8‑quart basket shines when you want to cook a full family meal at once. Burgers, chicken breasts, wings, and even small roasts fit without crowding. The included rack and skewer set lets you cook multiple layers, which is useful for batch‑cooking fries or chicken nuggets. Like the 3.7‑quart model, the basket is non‑stick and dishwasher‑safe, which simplifies cleanup. Reviews on Amazon, Best Buy, and Reddit frequently praise this model for its consistent crispiness, app integration, and higher capacity.
Pros
- Large 5.8‑quart basket that serves 3–5 people comfortably.
- Wi‑Fi and app control (VeSync) with remote monitoring and scheduling.
- 1700‑watt motor heats faster and handles larger, thicker foods better.
- 11–12 presets plus keep‑warm and shake‑reminder functions for convenience.
- Dishwasher‑safe basket and rack, plus rack and skewer set for multi‑layer cooking.
Cons
- Higher price than the 3.7‑quart model, especially at full retail.
- Larger footprint may be awkward for small kitchens or tight countertops.
- App setup can be tricky for users who are not comfortable with Wi‑Fi‑enabled appliances.
- Plastic body and basket, while dishwasher‑safe, may feel less premium than stainless‑steel models.
Final Verdict & Winner Declaration
When you look at Cosori Pro 3.7‑Quart Air Fryer vs Cosori Pro 5.8‑Quart Smart Air Fryer, which is better depends mostly on your household size and how you like to cook. The 3.7‑quart model wins for budget buyers, singles, or couples who want a simple, compact air fryer without the smart features. It is cheaper, easier to store, and still delivers solid performance for everyday fries, nuggets, and small roasts.
However, the Cosori Pro 5.8‑Quart Smart Air Fryer is the clear winner overall in this comparison. It offers more capacity, better power, and smart app control, which adds real convenience for busy families and meal‑preppers. Expert reviews and user ratings on Amazon, Best Buy, and Reddit consistently highlight its consistent crispiness, larger basket, and app integration as standout benefits.
The extra $10–$30 you spend over the 3.7‑quart version pays off in versatility, especially if you regularly cook for more than two people or want to schedule meals from your phone. For most households, the Cosori Pro 5.8‑Quart Smart Air Fryer delivers the best mix of features, capacity, and value, making it the smarter long‑term choice.
