Cosori 6.8-Qt Air Fryer Review — The Upgrade Worth Paying For?

When the Pro II Isn’t Enough
I’ve recommended the Cosori Pro II to dozens of people and I stand by it as the best air fryer for most families. But after 18 months using it for a family of five, I’ll admit the 5.8-quart basket causes me problems on specific evenings.
Bone-in chicken thighs for five people requires cooking in two rounds — four thighs in round one, then three more. That’s an extra 22 minutes at the end of a school night. The 6.8-quart model promises to fit that full batch in one go. After six weeks testing it, it does.

Cosori 6.8-Qt vs Cosori Pro II: What Actually Changed
| Feature | 6.8-Qt | Pro II 5.8-Qt |
|---|---|---|
| Capacity | 6.8 qt | 5.8 qt |
| Wattage | 1,700 W | 1,700 W |
| Presets | 8 | 12 |
| Shape | Square basket | Square basket |
| VeSync app | Yes | Yes |

Same wattage, same build quality, same app connectivity — the 6.8-Qt trades 4 presets for a larger basket. Those 4 extra presets on the Pro II (whole chicken, bread/cake, steak, and a defrost mode) are the ones I use most infrequently. The tradeoff works in the 6.8-Qt’s favour for practical family cooking.
What Works
Fits a full family batch in one go
Seven bone-in chicken thighs in a single layer. Five large salmon fillets side by side. A full bag of oven chips without any shaking. For families of five, this eliminates the double-batch problem entirely.
The basket’s square shape continues the Pro II’s advantage over round baskets — usable space in the corners means the stated capacity is actually close to the real usable capacity, unlike round baskets where the corners are wasted.
Cooking results identical to the Pro II
The same 1,700 W heating element, the same airflow design, the same LED display interface. Chicken thighs at 200°C for 22 minutes produced results I couldn’t distinguish from the same recipe in my Pro II. The extra basket size does not affect cook quality.
Same intuitive controls
Anyone who’s used the Pro II can use the 6.8-Qt immediately. The touchscreen interface is identical, the preset categories are the same, and the VeSync app connects and works the same way. The learning curve is zero if you’re upgrading from the Pro II.
Shake reminder works well for chips
The built-in shake reminder at the halfway point of any cook is something I use weekly for chips, wings, and nuggets. Small feature but genuinely prevents the forgetfulness that produces half-crispy chips.
What Doesn’t Work
Larger footprint requires planning
At 30 × 34 cm it’s meaningfully larger than the Pro II (28 × 32 cm). Measure your counter space before buying — 2 cm in each direction doesn’t sound significant until you’re trying to fit it into a specific cupboard alcove.
8 presets instead of 12
The loss of the whole chicken, bread/cake, steak, and defrost presets from the Pro II is the real trade-off. If you regularly use those specific functions, stay with the Pro II. If you mostly cook chicken thighs, chips, vegetables, and fish fillets, the 8 presets cover everything you need.
Price is £20 higher
Twenty pounds more for 1 additional quart of basket space. For a family that regularly cooks in two rounds when one would do, that £20 saves meaningful frustration every week. For a family of 3–4 who rarely overload the Pro II, it’s an unnecessary upgrade.
Practical Capacity: What Fits That Didn’t Fit in the Pro II
| Food | Pro II (5.8 qt) | 6.8-Qt |
|---|---|---|
| Bone-in chicken thighs (for 5) | 2 rounds | 1 round |
| Chicken wings (1 kg) | 2 rounds | 1 round (just) |
| Whole chips from 800g potatoes | 2 rounds | 1 round with shaking |
| Fish fingers (full pack) | 2 rounds | 1 round |
| Roasted vegetables (full Sunday prep) | 2 rounds | 1 round |
The practical benefit for a family of five is approximately 20–30 minutes per week saved, assuming one double-batch per evening session. Over a month, that’s 1–2 hours of cooking time recovered.
Verdict
The Cosori 6.8-Qt is a direct upgrade from the Pro II for large families — same excellent cooking, more space, fractionally less versatile on presets. The £20 premium is justified if you regularly cook for five or more people and find the Pro II too small.
If you’re a family of 3–4 and the Pro II has never felt genuinely cramped, save the £20 and stick with it.

FAQs
Is the Cosori 6.8-Qt available in the UK?
Yes — available on Amazon UK and Cosori’s website. Delivery is fast and it ships fully assembled.
Does the 6.8-Qt fit a whole chicken?
A 1.2 kg spatchcocked chicken fits. A whole un-spatchcocked chicken does not — the height is insufficient. Spatchcock it or buy a separate air fryer oven model.
Is there a Cosori larger than 6.8 quarts?
Cosori makes a dual-basket model and an air fryer oven/toaster combo for larger families. The 6.8-Qt is the largest single-basket Cosori air fryer in the standard range.
