Cosori Dual Basket Air Fryer (9-qt) vs Instant Vortex Plus Dual Air Fryer (7.6L)

Nine quarts versus 7.6 liters sounds like a spec sheet argument, but in practice it's the difference between fitting a whole tray of wings in one basket versus splitting them awkwardly across two. The Instant Vortex Plus testers literally noted that chips needed spreading out carefully just to crisp evenly — that's a capacity problem showing up on your plate. If you're feeding more than two people regularly, the Cosori's 4.5QT-per-basket layout removes a real constraint.

This isn't a minor spec gap — grill mode on the Cosori added genuine crunch to dishes in testing, and dehydrator mode means you can make jerky or dried fruit without a second appliance. The Instant Vortex Plus sticks to air fry, roast, bake, and broil. If you bought a dual-basket air fryer to replace multiple kitchen gadgets, the Cosori does that job. The Vortex Plus is an air fryer that happens to have two baskets.

Every reviewer who tested the Cosori flagged the controls as fiddly and non-intuitive. The Sync Cook and Sync Finish features — the headline dual-basket selling point — were unreliable in testing. Meanwhile, the Instant Vortex Plus was called the simplest to operate of any dual-basket model tested, full stop. If you're cooking under time pressure on a Tuesday night, that friction is real. The Cosori rewards patience; the Vortex Plus rewards people who don't have any.

The Cosori ships with a baking plate that actively drains fat and oil away from food as it cooks — Good Housekeeping specifically called out that it kept everything 'nicely crispy.' The Instant Vortex Plus has no equivalent. This matters most for fatty proteins like bacon, sausages, or chicken thighs, where pooling grease is the enemy of crispiness. It's a small accessory that punches above its weight, and you won't find it on the Vortex Plus at any price.
