Our verdict

Who this pressure cooker is for
The Duo Plus 9-in-1 in the 8 quart size targets people cooking for a household of five or more, or anyone who wants to meal prep a full week of grains, beans or shredded meat in a single batch. Instant Pot lists the 8 quart size as suitable for up to eight servings, which lines up well with weekly meal prep rather than single-portion cooking. A single person or couple with limited counter and cabinet space may find the footprint larger than needed, since this size sits close to 14.5 inches wide and just under 14 inches tall according to the manufacturer. It is a strong fit for anyone replacing several separate appliances, since it combines pressure cooking, slow cooking and other functions in one unit.
Functions, power and build explained
The Duo Plus 9-in-1 runs on 1200 watts at 120 volts and is UL and ULC listed, with nine built-in programs that Instant Pot's own product pages describe as pressure cook, slow cook, steam, saute, rice, yogurt, warm and related presets, plus the sterilizing and warming functions listed on this model's original packaging. The inner pot is stainless steel with a tri-ply bottom for even heating, and the lid and steam rack are stainless steel as well. It ships with a stainless steel steam rack with handles and comes with extra sealing rings, which is useful since rings wear out with regular use and can otherwise be a separate purchase. WhisperQuiet steam release technology is built in to reduce the loud hiss common to older pressure cookers.
Daily use and care
For meal prep, the appliance's main draw is walking away while a full batch of rice, beans or a whole chicken cooks unattended, then switching to the keep warm setting until you are ready to portion it out. The lid and inner pot are listed as dishwasher safe, which cuts down on the cleanup that a large pot usually demands, though the sealing ring benefits from being pulled out and washed separately since it can hold onto odors from strong-smelling meals. Instant Pot documents over 10 built-in safety mechanisms along with an anti-spin pot design, features aimed at people who are new to pressure cooking and want the appliance to manage the process safely rather than requiring manual monitoring, in line with the manufacturer's own instructions and safety documentation.
Trade-offs and how it compares
Against the Ninja Foodi XL 8 Qt Pressure Cooker Steam Fryer, which adds an air fry mode, the Duo Plus skips air frying in favor of a simpler, more classic function set built around pressure cooking, slow cooking and yogurt making. Against the smaller 6 quart Instant Pot Duo Plus, this 8 quart version trades countertop and storage space for meaningfully more batch capacity, which matters if you are cooking a week of meals rather than a single dinner. The main day to day trade-off is size and weight: a full 8 quart pot of liquid and food is heavy to lift and maneuver, and the unit itself takes up more cabinet space than most single-purpose slow cookers or rice cookers.
Verdict and who should size down
For batch meal preppers and larger families who want one appliance covering pressure cooking, slow cooking, steaming and yogurt making, the Duo Plus 8 Quart earns its place, supporting our score of 8.6 out of 10 for fitting that job well. Anyone cooking mostly single portions or living in a small kitchen with limited storage should look at the 6 quart version instead, since it covers the same functions in a smaller footprint. Shoppers who specifically want air frying built in should consider a combo unit like the Ninja Foodi XL rather than this model. For straightforward, high-capacity batch cooking without extra bells and whistles, this size of the Duo Plus does the job reliably.
