The verdict
Buy it if you cook for four or more and want one pot rather than two. Instant Brands publishes 1,500 watts at 120V~60Hz, a 8.0-quart capacity it rates for up to eight servings, eleven cooking functions— air fry, roast, bake, dehydrate, pressure cook, slow cook, sauté, steam, sterilize, warm and cook rice — a stainless-steel inner pot, and two interchangeable lids, one for pressure and one for air frying. Nothing else on this site does both of those jobs at eight quarts. The thing it gives up against the 8-quart Pro that held this slot until today is sous vide: it is not in Instant Brands' eleven-function list for this model, the Pro listed it, and we are not going to imply otherwise.
Why this page exists, and why the slot keeps moving. This is the fourth machine to hold our big-batch pressure pick in three weeks, and that is worth being straight about. The RIO Wide Plus lost its listing, the 8-quart Duo Plus that replaced it lost its listing, and on 2026-10-22 the 8-quart Pro that replaced THAT came back from Amazon as “Currently unavailable” with no offer and no price — on the same day the 6-quart Duo, Duo Plus, Pro and the 3-quart Duo Mini all stopped returning any item at all. Instant Brands' whole legacy line has left Amazon. This is what is left in eight quarts, and we will keep saying so plainly rather than pretending each swap was a planned upgrade.
Eight quarts is the whole argument
A pressure cooker is filled to two-thirds for solids and no more than half for anything that foams, so the number on the box is never the number you cook with. Eight quarts is about 5.3 usable quarts of roast-and-liquid, or roughly four quarts of bone broth or beans. A 6-quart pot is four and three respectively. That difference is the one that decides whether a bone-in pork shoulder goes in whole or gets cut down, and it is the only reason to buy a pot this tall.
It is also the reason not to. An 8-quart body is a genuinely large object to store and it takes longer to come up to pressure, because the machine is heating more air and more metal before it heats any food. If you cook for one or two, everything on this page is working against you — the 4-quart RIO Mini is the machine to read about instead, and what size Instant Pot to buy works the sizing through properly.
Two lids, and what that actually means day to day
This is a two-lid machine, not a one-lid one, and the distinction matters more than the marketing suggests. The pressure lid and the air-fry lid are separate pieces of hardware that swap on the same base. The upside is that each lid is a simpler object than a combination lid, and the pressure lid is dishwasher-safe. The downside is that the second lid has to live somewhere, and an 8-quart air-fry lid is not a thing that tucks into a drawer — Instant Brands includes a storage cover for it, which tells you it expects the lid to sit out.
The 6.5-quart Duo Crisp with Ultimate Lid solves that by doing both jobs under one lid, and it has a sous vide program this one does not. It is also a quart and a half smaller and cheaper. If you do not specifically need eight quarts, that is the better buy, and we would rather say so on this page than let the bigger number win by default.
What comes in the box, and why it is not padding
Instant Brands lists an air fryer basket, a broil tray, a dehydrator tray, a steam rack and the lid storage cover. On most appliances an accessory list is filler; on an air-fry combo it is load-bearing, because the air-fry functions are unusable without the basket and the trays, and buying them separately afterwards costs real money. Dehydrate in particular only exists if the tray does.
EvenCrisp is Instant Brands' name for the air-fry element and fan arrangement, and its published claim for it is 95% less oil than traditional deep frying. That is an oil-volume claim, not a crispness claim, and it is the kind of figure we report as the manufacturer words it rather than dressing up — Instant Pot versus air fryer is the page that argues out what an air-fry program on a pressure cooker can and cannot do.
The running cost, and the circuit
1,500 watts is the joint highest draw of any Instant Pot on this site, level with the 6.5-quart Duo Crisp. On a US average residential rate that is a few cents for a pressure cycle and meaningfully more for a long air-fry or dehydrate run, because air frying holds the element on where pressure cooking only heats until the pot seals. Our running-cost page does that arithmetic at the published rate, and says plainly that every figure is computed at full rated draw because no manufacturer publishes a duty cycle.
The practical caution is the circuit rather than the bill. A 15 A, 120 V kitchen circuit gives roughly 1,800 W of headroom. A 1,500 W cooker plus a kettle on the same circuit is over it. That is the same warning we give for the smaller Duo Crisp on the small-apartment page, and it applies harder here because nothing about an 8-quart pot is a quick job.
What Instant Brands does not publish
No working-pressure figure. That is the same gap the Pro had, and it is a real one: the only working-pressure numbers Instant Brands has ever published are the 10.2–11.6 psi in the older Duo and Duo Plus manuals, and both of those cookers are now off Amazon. So the honest position on this site is that no Instant Pot you can currently buy has a published pressure figure, and the only electric cooker that does is the Cosori 6-quart, which prints both bands in psi and kPa. If you convert recipes by pressure rather than by time, that matters — converting recipes explains why.
No external dimensions either, which is why this review does not tell you whether it fits under a cabinet. We would rather print that gap than a number we guessed.
Who should buy it, and who should not
Buy the 8-quart Duo Crisp if you cook for four or more, you batch-cook or make stock, and a crisp finish is on your list. It is the only machine here that does all of that in one vessel. Buy the 6.5-quart Duo Crisp with Ultimate Lid if eight quarts is more than you need — one lid, a sous vide program, less money. Buy the Ninja PossibleCooker PRO if you want the biggest pot on the site (8.5 quarts) and do not want pressure at all. Buy the Cosori 6-quart if a published working-pressure figure is what you are shopping on. And if you are starting from the top, the multicooker roundup ranks the whole field and the large-multicooker page is the one aimed at this size.
