An in-one figure is a count the seller prints on the box, and nothing in it obliges the listing to say what the places are. Of the 5 air fryer listings gathered here the counts run from 4 to 9, and two of them name none of their places at all. The honest reading of the highest count in this group is that a seller counted to 9 and left the reader to work out what was counted.

The count and the names are two separate claims
This catalog records two things about an in-one claim: the figure, and the modes the same listing goes on to name. They are not required to agree, and across these 5 listings they mostly do not. Two of them name as many modes as their own figure claims, and two name none.
The Chefman states a seven-in-one and then names air fry, bake, broil, reheat, dehydrate, defrost and keep warm, which is a count matched by a list. The Cosori states a nine-in-one, the highest figure in this group, and names nothing whatsoever. Between those two sits the Cuisinart, which states an eight-in-one and names four modes, half of what it counts.
What gets counted is not fixed
Where the places are named they are not the same places from one listing to the next. The Ninja Crispi states a four-in-one and names max crisp, bake, air fry and recrisp, a set in which air frying is itself one of the four. The Cuisinart names air fry, convection, broil and warm, so convection stands as a place in one listing while another treats the fan as the machine itself.
That is why a higher figure cannot be read as more machine. Two listings can reach the same total from different things, and one of them can count as a place what the other treats as the base. The catalog-wide count of in-one figures sets out how wide that spread runs.
What travels with a high count
Not size. All 5 of these listings state a capacity, across 5 different figures, and the highest in-one count does not sit on the largest of them. The listing with the lowest count is the one that states its capacity in two parts at once.
Not wattage either. Only three of the 5 state a wattage, from 1725W to 1800W, and two state none. The highest wattage here belongs to a listing whose in-one figure is not the highest. Set beside the quart-against-quart comparison, the pattern repeats: one field is filled in and the rest are patchy.
Reading an in-one figure off a box
The figure is a claim about how the seller has divided up the machine, and that division belongs to the seller. Where a listing names its places a reader can see the division and check it against the count. Where it does not, the figure carries nothing beyond itself, and the table below marks what is absent as "not stated" rather than guessing at it.
These 5 listings sit in 3 different subgroups, which is part of why the counts do not line up: a basket fryer and an oven with an air-fry setting are not dividing the same kind of machine. The category index keeps them filed apart for that reason.
On the listing filed here that states it, the figure stands alone: the Cosori states a nine-in-one and names none of the nine places. The count is a division of the machine made by the seller, and where the places go unnamed there is nothing further in the listing to read.
Is a higher in-one number better?
Nothing in these 5 listings supports that. The highest figure here names no modes at all, while two lower ones name every mode they count. A count and a list of named jobs are different claims, and only one of the two can be checked against anything.
What functions does a seven-in-one air fryer have?
The Chefman listing states a seven-in-one and then names them: air fry, bake, broil, reheat, dehydrate, defrost and keep warm. It is one of two listings in this group whose named modes match its own figure exactly.
Why do air fryer listings count different things?
Because nothing requires them to count the same things. Among these 5 the named sets overlap without agreeing: one counts air frying as a place inside its own total, another counts convection as a place, and two name nothing at all.
