Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
Cosori's Dual Basket is the counter-argument to the wattage race. Its two 4.25-litre zones run on 1,750 W, where the Ninja and Philips dual machines in this ranking are rated at 2,470 W and 2,750 W. Cosori says plainly on its page that the 1,750 W delivers results comparable to higher-wattage models — a claim we cannot verify ourselves, but the product page also carries a Stiftung Warentest 'Testsieger' badge for issue 01/2025. The underlying grade is behind test.de's paywall, so we rely on Cosori's statement.
The specification is reasonably complete: 39.1 × 46 × 30.3 cm, eight one-touch functions with independent zone control, a metal cooking chamber and dishwasher-safe baskets. Missing are the temperature range, the weight, any noise figure and the chemistry of the non-stick coating.
Price is the clearest advantage. cosori.de lists it at €199.99, but geizhals showed it from €116.94 in October 2026, which makes it the cheapest dual-drawer model here with test backing. Owner feedback on cosori.de is small but positive (27 ratings, 70% five-star).
Best for: households who want two zones and lower peak power, and who have 46 cm of counter width to spare.

FAQ
Frequently asked questions
Does lower wattage mean slower cooking?
Not necessarily. Wattage is the maximum the heater can draw; cooking speed depends on airflow and basket size too. Cosori claims results comparable to higher-wattage models, and its page cites a Stiftung Warentest test win in 01/2025.
Why is the price so different on cosori.de?
cosori.de lists €199.99, while geizhals showed retailer offers from €116.94 in October 2026. We use the street price.
