What does Cosori Dual Blaze technology mean and how does it work?

Dual Blaze technology uses two heating elements: one above and one below the basket. Unlike standard air fryers that only heat from above, this dual heating ensures more even cooking without needing to flip or shake food halfway through in most cases.

Does the Cosori Dual Blaze require preheating?

The Cosori Dual Blaze requires minimal preheating thanks to its dual heating elements that reach the target temperature faster. In practice, preheating is built into the preset programmes and happens automatically. The 20% lower energy consumption compared to the Philips 3000 XL is partly due to this efficiency.

Is the Cosori Dual Blaze suitable for a family of 4?

With its 6.4-litre capacity, the Cosori Dual Blaze suits a family of 3 to 4 people. You can cook approximately 500 g of fresh fries or 5 chicken drumsticks in a single batch. For families of 5 or more, a larger model like the Ninja FlexDrawer 10.4L would be more suitable.

Is the shake reminder function of the Cosori Dual Blaze useful?

Thanks to Dual Blaze technology, shaking has become largely unnecessary for normal portions. Cooking is even on both sides without flipping in 90% of cases. Shaking only remains beneficial when the basket is very heavily loaded. The appliance emits a discreet beep that some users find slightly too quiet.

Does the Cosori Dual Blaze offer good value for money?

At 139.99 euros, the Cosori Dual Blaze offers exceptional value for money with a 9.5/10 score in this category. It includes Wi-Fi connectivity, 12 programmes, Dual Blaze technology and a brushed stainless steel design. These features are typically found only in models costing 200 euros and above.

Design and Build Quality

The Cosori Dual Blaze features a modern, angular design that stands apart from the typical Philips roundness. The brushed stainless steel casing gives it a premium look. The key technical innovation is the dual heating element: one heats from above (like all air fryers) and a second heats from below the basket, theoretically eliminating the need to shake or flip food.

Build quality is very good for this price range. The non-stick coating is PFOA-free (FDA certified). The responsive touchscreen on the front panel has bright icons for all 12 programmes.

Cooking Performance

Fries and Potatoes

This is where Dual Blaze technology shows its clearest advantage. With 500 g of fresh-cut 9 mm fries at 195°C for 18 minutes without shaking, the result is impressive: fries are evenly golden on both sides with remarkable crispiness. The no-flip promise holds about 90% of the time — only heavily loaded baskets benefit from a quick shake.

Chicken and Meats

Chicken drumsticks (5 pieces) at 185°C for 22 minutes are excellent: skin is evenly golden without flipping, meat perfectly cooked (78°C internal). The dual heating enables faster cooking — we saved 3-5 minutes on most meat dishes. For steak (220 g, 2 cm thick) at 230°C, the higher max temperature is a real asset, producing a well-marked crust.

Vegetables

Courgettes, aubergines and peppers at 185°C for 14 minutes come out perfectly caramelised on both sides without flipping. Brussels sprouts halved at 190°C for 12 minutes develop a delicious crispy exterior. For those looking to cook healthy with an air fryer, the Cosori is excellent for even vegetable cooking.

Ease of Use

The touchscreen is intuitive with 12 clearly identified programmes. The major asset is Wi-Fi connectivity via the VeSync app, offering remote control, 100+ recipes, custom programmes and completion notifications. Setup takes under 3 minutes. The app is well designed and stable on both iOS and Android. For more on connected air fryers, see our 2026 connected air fryer comparison.

Cleaning is straightforward with the dishwasher-safe non-stick basket. The lower heating element creates a slight additional area to clean, but it is manageable.

Energy Consumption

At 1,750 W, the Cosori is surprisingly economical. For an 18-minute fries session at 195°C, we measured 0.44 kWh — 20% less than the Philips 3000 XL for similar cooking time, thanks to dual heating efficiency.

If you need dual simultaneous cooking, look at the Ninja Double Stack. For simpler and cheaper without Wi-Fi, the Philips 3000 XL remains solid. See all our recommendations in the complete guide to the best air fryers 2026.

The Dual Blaze Technology Explained

The Cosori Dual Blaze's central innovation deserves a detailed explanation. Conventional air fryers heat only from above, with the heating element positioned above the fan. Hot air is blown downward and circulates around the food. The result: the top face of food receives more direct heat than the bottom face resting on the basket grid.

Cosori solved this with a second heating element integrated beneath the basket floor, emitting heat upward to warm the underside of food directly. The combined effect of both elements creates an enveloping cooking environment that more closely resembles deep frying, where food is surrounded by hot oil on all sides. In our test with 500 g of fresh fries, without shaking, the Cosori Dual Blaze scored 9.2/10 for uniformity versus 7.8/10 for the Philips 3000 XL without shaking. With a mid-cook shake, the Philips reaches 8.9/10, but the Cosori hits 9.4/10 — the dual heating advantage is real and measurable.

Comparison with the Competition

Model	Price	Technology	Wi-Fi	Nura Score
Cosori Dual Blaze 6.4L	€139.99	Dual heating element	Yes	8.9/10
Philips 3000 XL 6.2L	€119.99	RapidAir Starfish	No	8.7/10
Philips Combi XXL Connected	€349.99	RapidAir Combi + IR	Yes	9.0/10
Ninja Double Stack XL	€229.99	Dual drawer	No	9.4/10

The Cosori Dual Blaze occupies a unique position: it is the only single-drawer air fryer with dual heating element AND Wi-Fi under €150. The Philips Combi XXL Connected offers even more advanced technology (infrared + temperature probe), but at €350. For a budget of €100-180 with connectivity, the Cosori has no direct competitor.

Who Is the Cosori Dual Blaze Ideal For?

Tech enthusiasts who want to control their air fryer from a smartphone and access a recipe library
Busy people: no-flip cooking lets you start cooking and attend to other things
Families of 2-4 people who mainly cook chicken, vegetables and fish (foods that benefit most from dual heating)
Meat lovers: 230°C max enables a genuine Maillard reaction

Detailed Final Verdict

The Cosori Dual Blaze Smart 6.4L is an engineering success for its price point. The Dual Blaze technology delivers on its promise of more even cooking, and the VeSync app is one of the best in the sector. At €139.99, it offers a premium feature set (Wi-Fi, 230°C, dehydration, 12 programmes, dual heating) with no direct equivalent on the market. Confirmed Nura Score: 8.9/10.
