COSORI Pro Gen 2 5.8-Qt Air Fryer Review (2026)

Why you should trust this review

I bought the Pro Gen 2 myself and ran it through real kitchen use rather than a press-event afternoon. COSORI did not provide the unit and had no input on this review. Smart kitchen gear earns skepticism for good reason: WiFi sounds great in a press release and usually delivers laggy, unreliable performance that gets switched off after the first week. I went in expecting to do exactly that, and I tested specifically to find out whether the connectivity would still be working after weeks of cooking, not just on day one.

Every result below comes from my own cooks, my own router, and my own probe thermometer. When I cite a latency number or a voice-command success rate, I logged it as it happened.

How we evaluated

I ran my standard multi-session cooking protocol plus a set of smart-feature tests over about 8 weeks and 50-plus sessions. I logged every remote command sent from the VeSync app and timed execution latency from tap to appliance response. I tested voice control across 30 Alexa command attempts, recording successes, failures, and misinterpretations. I deliberately killed the WiFi router mid-cook to see whether the unit would keep going or fail.

For app recipes I followed 10 different app-guided recipes start to finish, including multi-step ones that use the mid-cook shake reminder, and checked the app’s suggested times and temperatures against my own internal-temperature verification. Cooking-performance tests matched the protocol I used on the Pro LE so the two are directly comparable, since they share heating architecture.

Cooking performance

Cooking results are essentially identical to the COSORI Pro LE, which is a compliment, since the Pro LE is a proven performer. The Gen 2 uses the same basket geometry with a slightly higher 1700W element versus the Pro LE’s 1500W, and the practical effect is marginally faster temperature recovery after you load cold food, with a small but noticeable edge in the first five minutes of high-heat cooks. Chicken wings at 400F for 22 minutes with a flip at 11 produced shatteringly crisp skin and a 175F interior, matching the Pro LE exactly. Frozen fries at 380F for 14 minutes came out evenly golden. The temperature range runs 170 to 400F, which covers everything I actually cook in an air fryer.

Capacity and everyday use

The 5.8-quart basket is 16 percent larger than the 5-quart Pro LE, which is a modest but real upgrade. In practice it meant roughly one extra chicken thigh or two extra servings of fries per batch, enough to matter when you are cooking for more than one or two people and tired of running back-to-back loads. At 12.6 by 11.4 by 13.1 inches and 12.1 pounds, it takes up a normal air fryer footprint on the counter, so the extra capacity does not come with a punishing size penalty. For the same price tier as the smaller Pro LE, the added room is a genuine reason to consider the Gen 2 even before you get to the smart features.

Smart features that actually work

This is where the Gen 2 separated itself from the usual disappointment. VeSync app commands executed in 1 to 2 seconds across the whole test period, versus the 5 to 8 seconds I have seen on competing smart units, so it never felt like fighting the app. Across 8 weeks I had two dropped connections, both of which reconnected automatically within about 30 seconds. The app uses a 2.4GHz protocol, which simply carries better through walls than the 5GHz-only setups that doom a lot of smart appliances.

Voice control held up too. Of 30 Alexa command attempts, 28 executed correctly, with one misinterpretation (it heard “turn off” as “turn on”) and one non-response, a 93 percent success rate that is competitive with dedicated smart-home devices. Saying “Alexa, start the air fryer” simply worked, with no workarounds. Critically, when I killed the WiFi mid-cook the unit kept running its last command state and finished the session, so connectivity is an enhancement rather than a single point of failure.

App recipes and the catch

The 100-plus pre-loaded app recipes turned out to have genuine utility rather than being filler. They include step-by-step guidance with shake reminders at mid-cook, and those reminders actually changed my cooking for the better. A teriyaki salmon recipe at 380F for 12 minutes with a flip-and-glaze prompt at the 6-minute mark produced excellent results, because salmon really does benefit from being repositioned partway through and the app made sure I did it.

The honest catch is that the full feature set requires creating an app account; in offline-only mode you are limited to basic manual control via the touchscreen. You keep all temperature and timer functions locally without a phone or WiFi, so nothing essential is gated, but the recipe library, remote monitoring, and shake reminders all need the account. The app notifications can also get intrusive if you do not set your alert preferences during initial setup, so configure those on day one.

Who should buy the COSORI Pro Gen 2?

Buy it if you want smart appliance integration that genuinely works rather than a marketing checkbox, or if you cook regularly from recipes rather than by intuition and would use the guided shake reminders. Buy it if you are already in the Alexa or Google Home ecosystem and want your air fryer to participate meaningfully. Buy it if the extra 16 percent of basket capacity is useful for your household.

Skip it if you have no interest in app control and are happy running presets manually, in which case the Pro LE gives you the same cooking without the app dependency. Skip it if you refuse to create an app account, since offline mode strips away exactly the features that make this model worth choosing. Skip it if you want the largest possible basket, where a 6-quart unit edges it out, though those alternatives drop the smart features.

The verdict

The COSORI Pro Gen 2 is the smart air fryer I can actually recommend without an apology. The cooking matches the trusted Pro LE, the 5.8-quart basket adds real capacity, and the smart layer (fast app commands, reliable voice control, useful guided recipes) holds up through extended use instead of getting abandoned after a week. The app-account requirement and the chatty default notifications are the only real friction, and both are easy to live with once you know about them. If you want your air fryer to participate in a smart home and do it well, this earns its label.
