Cosori TurboBlaze Review: The One You Can Talk Over
Reviewers keep reaching for the same word about this air fryer, which is quiet. The measured temperature accuracy is the part they disagree about.

Cosori TurboBlaze
Good · researched from 4 sources
The quietest air fryer any of our sources had measured, and quick enough that the speed claims hold up. If you cook two things at once you want a dual basket machine instead, and if you air fry a lot of small items the crisping tray will annoy you.
- Buy if
- Open plan kitchens where appliance noise carries into the living room · Households cooking one thing at a time for two to four people · Anyone who wants the basket to go in the dishwasher
- Skip if
- People who want two zones at two temperatures · Small counters, since it wants about 40cm of depth · Anyone frying a lot of small items that can fall through a tray
We don’t list prices, because Amazon’s change hourly.
The noise is the actual selling point
Air fryers are loud in a specific and irritating way. They sit on a counter in a room people are usually also living in, and they run for twenty minutes making a noise like a hairdryer in the next room.
KitHub measured this one at under 53 dB and called it the quietest high-performance air fryer they had tested, putting the cause on a DC motor where most of the category uses AC. The Air Fryer Kitchen got to the same conclusion by ear, describing it as quieter than most after weeks of daily use.
That is the thing to buy it for. Everything else it does well, other machines also do well.
The temperature question
Here the sources part company, and it is worth knowing which one matches how you cook.
KitHub reports plus or minus 2F and contrasts that with a Ninja swinging 5 to 8F. TechGearLab set it to 400F, ran it for twenty minutes, and logged an actual average of 395.7F. They scored temperature accuracy 7.0 out of 10, the lowest of their category scores for this machine.
Those findings are less contradictory than they look. Running consistently 4F below a setpoint is stable but slightly cold, which is a calibration offset rather than a fluctuation. In practice you learn it and nudge the dial up. It only matters if you are following recipes to the degree.
Speed
KitHub got it to 400F in about three minutes and clocked 5 lb of wings in seventeen minutes and a frozen pizza in eight. TechGearLab scored cooking speed 8.4 and cooking quality 8.5, which put the machine second of the ten they ranked.
The Air Fryer Kitchen ran a broader menu, including a whole chicken, roasted vegetables, muffins and corn, and reported everything cooking evenly. Between them that covers most of what an air fryer gets asked to do.
Two design decisions you should check against your kitchen
The crisping tray has a hole in the middle. TechGearLab calls this the main design flaw, because smaller pieces drop through it during cooking. If a lot of what you cook is small, that is a daily annoyance rather than a one-off.
And it needs roughly 40cm of counter depth per KitHub, which is more than the listed footprint implies once you account for opening it. Measure first.
The single basket
One basket, one temperature, one thing at a time. KitHub lists this as the main loss against dual-zone machines, and it is the one limitation here that no firmware or technique gets around.
For two to four people cooking one component, it is fine. For a family dinner where the chips and the chicken want different temperatures, you are running two cycles, and the machine's speed advantage gets spent covering for that.
How it scored
The overall 8.0 is the weighted average of these five criteria — we never adjust it by hand.
Cooking performance
TechGearLab scored cooking quality 8.5 and speed 8.4, ranking it second of ten. The Air Fryer Kitchen cooked a whole chicken, wings and muffins with even results.
Value
Second of ten at TechGearLab and 4.7 out of 5 at The Air Fryer Kitchen, without being the most expensive thing in either group.
Build quality
Ceramic-coated basket that KitHub found stayed clean, but they also report a stiff basket latch and TechGearLab found a hole in the crisping tray that small food falls through.
Ease of use
TechGearLab scored ease of use 8.2 and cleaning 7.0. Basket and crisper plate are dishwasher safe.
Noise
KitHub measured under 53 dB and called it the quietest high-performance air fryer they had tested. The Air Fryer Kitchen independently noted it as quieter than most.
Pros and cons
What we liked
- Measurably quieter than the competition, quiet enough to hold a conversation over
- KitHub reached 400F in about three minutes from cold
- Ceramic-coated basket and crisper plate are both dishwasher safe
- Nine cooking modes including proof and dehydrate, not just a fan and a timer
What we didn’t
- TechGearLab found small pieces of food drop through the hole in the centre of the crisping tray
- Single basket, so no cooking two things at different temperatures
- KitHub reports a stiff basket latch
- Needs about 40cm of counter depth, which is more than it looks
- Sources disagree on how accurately it holds temperature

How we researched this
We have not had this unit on the bench. This review synthesises the manufacturer’s published specifications, independent measurements and owner reports listed below. Every figure on this page comes from one of those sources rather than our own measurement.
4
sources reviewed
TechGearLab is the most instrumented source and supplied the capacity, dimensions, power figure and the 20 minute temperature test, plus their category scores. KitHub supplied the noise measurement, the preheat figure and the fan speed. The Air Fryer Kitchen contributed extended daily use over several weeks and the temperature range. We could not read Cosori's own product page, so every specification here is attributed to whichever reviewer measured or reported it, and where two sources give different numbers, as they do on wattage and on temperature accuracy, the table and the text carry both.
What we read
Common questions
Is the Cosori TurboBlaze actually quieter than other air fryers?
How accurate is the temperature?
Can I cook two different things at once?
Is it easy to clean?
How much counter space does it need?
The bottom line on the Cosori TurboBlaze
The quietest air fryer any of our sources had measured, and quick enough that the speed claims hold up. If you cook two things at once you want a dual basket machine instead, and if you air fry a lot of small items the crisping tray will annoy you.

Anova Precision Cooker 3.0
The temperature control is as good as any lab has measured on a domestic circulator. The one thing everybody complains about is a timer that starts before you put the food in.

Breville Smart Oven Air Fryer Pro
One lab ranked it first of eleven and gave its interface a perfect ten. It also measured the temperature running five degrees hot, which matters more for baking than for anything else it does.
Cooking Appliances
Instant Pot Duo 7-in-1
It is not rated for pressure canning low-acid food, which is the one thing worth knowing before you trust it with anything. Everything else it does well enough to replace four appliances.
