Cosori Dual Basket 8.5L specifications and in-depth review

Cosori Dual Basket 8.5L

Manufacturer: Cosori

The Cosori Dual Basket 8.5L is a basket-style air fryer with a combined capacity of 8.5 litres, split across two 4.25-litre compartments. It offers eight preset cooking functions — air fry, bake, roast, toast, dehydrate, broil, reheat, and keep warm — covering a broad range of everyday cooking tasks. A two-year warranty is included with the unit.

The appliance draws 2000W during operation and supports a cooking temperature range of 35°C to 230°C. It features digital controls, a viewing window, and an interior light for monitoring food without opening the drawer, along with a shake reminder function to prompt stirring or flipping mid-cook. Dual zone sync is supported, allowing both compartments to finish cooking simultaneously. There is no preheat function, and the unit does not support smartphone remote control, Alexa, or Google Assistant. The dishwasher-safe basket simplifies cleanup, and the unit measures 440 mm wide, 391 mm deep, and 303 mm tall, weighing 8.7 kg.

Pros
  • A total cooking capacity of 8.5 litres split across two 4.25-litre compartments allows larger quantities of food to be prepared at once
  • Dual zone sync enables both compartments to finish cooking simultaneously, useful when preparing multiple dishes
  • The viewing window and interior light allow users to monitor food during cooking without opening the drawer
  • Eight preset functions — including dehydrate, broil, and keep warm — cover a wide range of cooking tasks beyond basic air frying
  • The dishwasher-safe basket simplifies cleanup after use
  • A two-year warranty is included with the unit
Cons
  • At 8.7 kg and with dimensions of 440 x 391 x 303 mm, the unit is large and heavy, requiring significant dedicated counter space
  • There is no preheat function, which may affect cooking consistency for certain recipes
  • Only a single heating element is used across both compartments, despite the dual-basket layout
  • No smartphone remote control, Alexa, or Google Assistant support means the unit cannot be operated or monitored remotely
Who is this for?

This air fryer suits households that regularly cook for larger groups, where the 8.5-litre total capacity across two compartments allows different foods to be prepared at the same time with dual zone sync ensuring everything finishes together. Users who appreciate hands-on cooking control will find the eight preset functions — spanning dehydrate, broil, toast, and more — genuinely versatile for varied meal preparation. Those who prefer low-maintenance cleanup will benefit from the dishwasher-safe basket, and anyone who wants visibility into the cooking process without lifting the drawer will appreciate the viewing window and interior light.

Who is this NOT for?

Users with limited counter space will struggle to accommodate this unit given its 440 x 391 x 303 mm footprint and 8.7 kg weight, making it a poor fit for smaller kitchens where space is at a premium. Those who want to control or monitor their cooking remotely will find the lack of smartphone connectivity, Alexa, and Google Assistant support a clear limitation. Cooks who rely on a preheat stage for consistent results will also find this unit lacking, as no preheat function is available, and the use of a single heating element across both compartments may not suit users expecting fully independent dual-zone cooking.

The Cosori Dual Basket 8.5L measures 440 mm wide, 391 mm deep, and 303 mm tall, with a total volume of just over 52,128 cm³, and weighs 8.7 kg — a substantial footprint that will require a dedicated spot on the countertop. The basket is dishwasher-safe, making post-cook cleanup more convenient without the need for hand-washing.

Final Verdict

The Cosori Dual Basket 8.5L is a capable, high-capacity air fryer built for households that cook in volume and value cooking versatility. Its 8.5-litre split capacity with dual zone sync is the standout feature, enabling two different foods to be cooked simultaneously and finish at the same time — a genuinely practical benefit for family meals or batch cooking. The eight preset functions, interior light, viewing window, and dishwasher-safe basket round out a well-equipped feature set. That said, its considerable size and weight mean it demands real counter space, and the absence of smart connectivity or a preheat function will matter to some users. For those whose kitchen setup and cooking habits align with what it offers, the Cosori Dual Basket 8.5L is a solid and functional choice — best suited to regular, high-volume use rather than occasional or small-batch cooking.
