COSORI Dual Basket 8.5L: the air fryer with 2 chambers for couples

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

By Seydhan Cakmak · Editor-in-chief · Updated: · AI-translated from the German original

Chips and fish fillet at the same time, and both done at exactly the same moment: the COSORI Dual Basket has two separately controllable chambers and a Sync Finish programme that automatically matches different cooking times. With a viewing window and interior light in both baskets, you keep an eye on everything. As the Stiftung Warentest (German consumer foundation) winner, with just 1,750 watts for both zones, it is the premium pick of the comparison: the deliberately somewhat larger choice for couples and small families.

COSORI Dual Basket 8.5L: what works, what doesn't?

What works well

  • 2 separate chambers: two dishes at different temperatures at the same time
  • Sync Finish: both baskets finish at the same time automatically
  • Viewing window in both: browning visible left and right, with interior light
  • Stiftung Warentest winner: independently awarded cooking result
  • Energy saving & quiet: only 1,750 W for both zones, quiet copper motor (~53 dB)

Points of criticism

  • Wide footprint: 46 cm wide, needs space on the worktop
  • No Wi-Fi/app on the device: control only directly on the display
  • Higher price: ~€123, the most expensive but most powerful in the comparison

Build quality & everyday use

What carries the COSORI Dual Basket 8.5L in everyday use: 2 separate chambers (two dishes at different temperatures at the same time) and Sync Finish (both baskets finish at the same time automatically). We have to be honest about the weaknesses: wide footprint, as 46 cm wide needs space on the worktop.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“COSORI Dual Basket 8.5 L (CAF-R901-AEU): 2 separate chambers and Sync Finish, and the trade-off is a wide footprint. At 9.1/10 a clear recommendation from €123.”

Frequently asked questions about the COSORI Dual Basket 8.5L

What does an air fryer with 2 chambers offer?
With two separate zones you cook two dishes at once at different temperatures and times, for example chips at 200 °C and salmon at 180 °C. The COSORI Dual Basket's Sync Finish programme matches both cooking times so everything lands on the plate at the same time.
Is the COSORI Dual Basket too big for a small kitchen?
At 46 cm wide it is the largest device in the comparison and needs worktop space accordingly. For genuine mini kitchens, a 2 or 4 litre single variant makes more sense. For couples and small families who regularly cook two components, the space is worth it.
Does a dual-zone fryer use twice as much electricity?
No. The COSORI Dual Basket works with a total of 1,750 W for both zones, not per basket. Since you cook two dishes in one go instead of one after the other, it is often even more efficient overall than two separate cooking runs.
Why is the COSORI Dual Basket our recommendation?
Stiftung Warentest mainly assesses even cooking results, handling and energy efficiency. The combination of two controllable zones, viewing window, Sync Finish and a very good browning result tipped the balance here.
