Description
Where will a 20 inch wide oven live between meals?
Countertop ovens are bought on capability and returned on footprint. The Ninja SP101 measures 19.72 inches wide by 7.56 inches deep by 14.96 inches high and weighs 22.9 pounds, and the answer Ninja gives to the footprint problem is the reason this model exists: the whole oven flips up and back to stand vertically against the backsplash when it is not cooking. That turns a 19.72 inch wide occupation of the counter into something much closer to a 7.56 inch strip.
Decide whether that trade works in your kitchen before anything else. The flip requires clearance behind the unit and a backsplash it can lean against, so it suits a counter run against a wall and does not suit an island. It also means the oven is being moved regularly, which is a different relationship with a 22.9 pound appliance than leaving it in one place.
The capacity question is the other half. Ninja states the oven fits a 13 inch pizza or up to nine slices of toast, and that it air fries up to 4 pounds. That is genuinely family sized for a countertop unit, and it is the reason to consider this over a smaller basket style fryer. The specification table lists Number of Shelves as 1, so this is a single level oven: everything cooks on one rack or one pan, and a full sheet of vegetables and a tray of chicken are two sessions, not one.
The specification you must read before ordering: this is a Renewed listing
The product title includes the word Renewed, and that changes the purchase more than any cooking function on the page. A renewed unit is a refurbished one, sold after inspection and testing rather than as new stock. Cosmetic condition, packaging, accessory completeness and warranty terms all differ from a new unit, and they differ by seller rather than by a single published standard. The listing shows a rank of 163rd in Renewed Home and Kitchen alongside 241st in air fryers, confirming which shelf it sits on.
If you are comparing this against a new SP101 on price alone, the comparison is incomplete without the warranty terms. Read them on the live listing before ordering. This site also carries a review of the standard Ninja SP101 Foodi listing, which is the same oven under different sale conditions.
The wattage contradiction, stated plainly
The listing gives the power draw two different ways. The title says 1800w. The description and the feature bullets both say 1750 watts. Those cannot both be right, and there is nothing in the record that settles it. The difference does not matter for cooking, but it matters for circuit planning in an older kitchen where an oven, a kettle and a microwave may share a run. Plan for the higher figure and confirm on the manufacturer page.
Two more fields are simply wrong rather than ambiguous. Color is recorded as Ninja SP101-RED., which is a model code rather than a color. Power Source is recorded as AC adapter, which is not how a 1750 watt oven is powered; it plugs directly into a wall outlet on a 36 inch cord, as the description states. And one feature bullet contains a stray row of hyphens where text was stripped out during import.
Living with it: eight functions, one rack, and a crumb tray
The listed functions are air fry, air roast, air broil, bake, bagel, toast and dehydrate, plus a keep warm setting. That is seven cooking modes and one holding mode, which is where the 8 in 1 figure in the title comes from. Control is by knob rather than a touch panel, with a toast darkness selector, and Ninja quotes a 60 second preheat and family meals in as little as 20 minutes.
In practice the modes that change a weeknight are air fry and toast. Air fry at this capacity replaces a basket fryer without the batch limit, and a 9 slice toast capacity is more than most households need at once. Dehydrate is a slow, low temperature mode that ties the oven up for hours, so it is useful but not casual.
Cleaning centers on the crumb tray, which the listing describes as removable, and an accessible back panel. The included accessories are a wire rack, a 13 by 13 inch sheet pan, an air fry basket and a recipe book. A dropdown door in tempered glass and stainless steel means the door swings out toward you and needs clearance in front, which is another reason the flip up storage matters: parked upright, the door faces the wall.
One practical detail the listing does supply is the cord length, quoted at 36 inches. That is short by countertop appliance standards, so the outlet needs to be close to where the oven parks, and an extension cord is a poor idea on a heating appliance drawing this much power. Measure the distance from your intended spot to the nearest socket before ordering.
What wears on this class of oven is the nonstick on the basket and pan, and the door hinge on a unit that is moved daily. The listing records 129 customer ratings averaging 4.2 stars, which for a renewed listing is a small sample and a slightly lower average than the same model tends to carry when sold new.
What would send you elsewhere
If your counter has no wall to flip against, the storage advantage disappears and you should choose on capacity and controls instead. The Breville Smart Oven Air Fryer Pro is the larger, more configurable answer with multiple rack positions, at a much higher price and a permanent counter commitment. At the other end, the BELLA 7 in 1 air fry toaster oven covers similar functions in a smaller and simpler box.
If air frying is the only function you actually want, a dedicated fryer wastes less space and heats faster. The Kalorik MAXX dual zone oven is the two basket approach, which lets two foods cook at different settings at once, something a single rack oven cannot do. The air fryers category and the toaster ovens category separate those two ideas out.
Who should buy this listing, and who should not
Buy it if you want a family sized air fry and toast oven, you have a wall to flip it against, you are comfortable with a single cooking level, and you have read and accepted the renewed condition and its warranty terms. On those conditions it is a lot of oven for the counter space it eventually occupies.
Do not buy it if you need two independent cooking zones, if you need more than one rack level, if your counter is an island, or if you want the warranty and packaging of a new unit. And whichever way you go, settle the 1750 versus 1800 watt question against your kitchen circuit rather than assuming the lower figure.
