Instant Pot vs Ninja PossibleCooker is a choice between two cooking routines. The Duo 6 Qt can pressure-cook beans, rice and stews; the PossibleCooker Pro Plus MC2001 gives you an 8.5-quart pot for larger meals and oven finishing. The Ninja does not pressure-cook, and neither of these models air fries.
Quick verdict: choose the cooker your recipes need
Choose the Instant Pot Duo if pressure cooking is the reason you are buying a multicooker. Choose the Ninja PossibleCooker Pro Plus if you mainly want to brown ingredients, slow-cook bigger batches and serve from the same removable pot.
If you already own a working pressure cooker, the Ninja adds a different workflow. If you want one machine to speed up suitable recipes, the Duo is the more useful starting point.

Pressure-cooked staples or large slow-cooked meals?
Illustration of meal choices, not cooking results from either appliance.
The Duo makes sense when your regular meals include pressure-cooker recipes for beans, grains, soups or tougher cuts. But a 20-minute pressure-cook setting does not mean dinner is ready in 20 minutes: the manual separates preheating, cooking and pressure release. The amount of food and starting temperature affect that first stage.
Its usable capacity also matters. Follow the pressure-cooking fill line; expanding foods such as rice and dried beans must stay at or below the half-full line. A 6-quart pot is not six quarts of pressure-cooked food.
The Ninja suits a different day: sauté first, then leave a larger meal cooking and bring the pot to the table. Its removable pot can finish in an oven up to 500°F—for example, to brown a casserole topping. That rating applies to the pot, not the electrical base.
The Duo also has a slow-cook program. The reason to choose the Ninja is therefore its larger cooking vessel and serving workflow, not a claim that the Duo cannot slow-cook.
What independent use tells us
The Kitchn’s Micki Wagner used the PossibleCooker Pro Plus for chicken tikka masala and chicken paella and reported tender chicken thighs. She particularly appreciated its capacity and visible timer. However, her September 2026 report explicitly covered only slow cooking; it does not establish performance for the other eight modes or superiority over the Duo.
That supports considering the Ninja for its intended slow-cooking routine. It is not evidence to buy it instead of a pressure cooker when speed is your main requirement.
Which is easier to live with?
The Duo has a stainless-steel inner pot that can go in the dishwasher. Its pressure lid also needs attention to the sealing ring, valves and small removable parts. If you dislike maintaining a pressure lid, that is a meaningful ownership difference.
The Ninja’s glass lid lets you see the food, but its larger vessel takes more sink and storage space. Its official footprint is 16.34 × 14.45 inches, so measure the counter before ordering. Follow the included care instructions for the coated pot; easier serving does not eliminate cleanup.
Buying from outside the US? Check the local model, voltage, delivery and warranty before paying. Amazon may redirect these links to a local match; confirm that the destination still has the cooker and features discussed here.
Which should you buy at today’s price?
Buy the Duo when pressure cooking is useful to your weekly meals. A cheaper Ninja offer still would not replace that function. Skip the Duo if you mainly want a spacious pot for entertaining and do not expect to use pressure cooking.
When the Ninja is worth paying more for
Buy the PossibleCooker Pro Plus when you will use its larger capacity and cooker-to-oven workflow often. Skip it if you cook small portions, have limited counter space or expect it to shorten meals through pressure cooking. Compare the current prices and included accessories rather than paying for a higher function count.

Common buying questions
Can the Ninja PossibleCooker replace an Instant Pot?
For slow cooking or sautéing, it may cover the recipes you use. It cannot replace the Duo’s pressure-cooking function. Choose by your recipes, not the number of modes.
Is the PossibleCooker Pro Plus the same as the Pro?
No. This comparison uses the nine-mode MC2001 Pro Plus in Blue Macaron. The older MC1001 Pro has eight modes. Check the model number, especially after an international Amazon redirect.
Does the Instant Pot Duo air fry?
No. The linked Duo is a seven-function pressure cooker, not a Duo Crisp. The linked Ninja PossibleCooker Pro Plus also has no air-fry mode.
