Ninja Flip SP151 Renewed Review: Worth It in 2026?
The Ninja Flip Toaster Oven & Air Fryer SP151 (Renewed) is an 8-in-1 countertop air fryer toaster oven built around a low-profile cooking chamber that flips upright for storage. Its strongest use case is a small or crowded kitchen where one appliance needs to handle toast, pizza, air frying, roasting, baking, broiling, bagels, and dehydrating without permanently occupying its full countertop footprint.
This Ninja Flip SP151 Renewed review focuses on the buying decision that changes with a refurbished unit: the cooking platform is well documented and independently tested, but condition, packaging, and included accessories deserve extra attention. The result is a capable space-saving oven with strong everyday performance, balanced by limited vertical cooking room and the need to inspect a renewed unit carefully on arrival.
Quick Verdict

Ninja Flip Toaster Oven & Air Fryer SP151 (Renewed)
A flip-up 8-in-1 air fryer toaster oven designed for broad everyday cooking in kitchens where counter space matters.
Rating: ★★★★☆4.0/5
Best For: Small households wanting one fast, versatile oven that can be flipped up after use.
Key Specs
1800W • 8 cooking functions • 85–450°F • fits a 12-inch pizza or up to 6 toast slices
Key Advantage
Flip-up storage cuts the appliance’s resting countertop footprint.
Main Trade-off
The shallow chamber gives less vertical room than full-size toaster ovens.
Bottom Line
The renewed SP151 is a sensible space-saving multi-cooker when the unit arrives complete and in the expected condition. Buyers needing tall-oven capacity or maximum refurbished-condition certainty should compare alternatives.
At a Glance
- Eight modes cover air fry, roast, broil, bake, pizza, toast, bagel, and dehydrate.
- The oven flips upright to reduce its countertop footprint by 50% when stored.
- Its listed capacity covers a 12-inch pizza, up to 6 toast slices, or up to 4 lb of food.
- Six infrared heating elements support a listed 85–450°F temperature range.
- The supplied set includes an air fry basket, sheet pan, wire rack, and removable crumb tray.
- The renewed condition adds a separate need to verify cosmetic condition, accessories, and return coverage.
Verified Specifications & Buyer Implications
| Attribute | Verified Detail | Why It Matters |
|---|---|---|
| Power | 1800W | This is a high-draw countertop appliance, so it should not be casually stacked on a heavily loaded circuit with other high-wattage devices. |
| Functions | 8 cooking modes | The mode set can replace several routine toaster-oven and air-fryer tasks without requiring separate appliances. |
| Temperature | 85–450°F | The broad range supports low-temperature dehydrating through higher-heat air frying, roasting, and pizza cooking. |
| Dimensions | 17.01″D × 15.75″W × 7.68″H | The low body fits wide foods but sacrifices vertical clearance, which matters for tall baking dishes and larger roasts. |
| Capacity | 12-inch pizza; 6 toast slices; up to 4 lb | Capacity is family-friendly for flat foods and one-layer batches, but it is not equivalent to a deep countertop oven cavity. |
Design & Build Quality
The SP151 uses a wide, low stainless-steel design with a drop-down door, digital controls, removable crumb tray, sheet pan, wire rack, and mesh-style air fry basket. The distinctive feature is the hinge system that lets the whole oven rotate upward against the backsplash after cooking, reducing the space it occupies while idle.
That design solves a real storage problem, but the low chamber is the compromise. It is better suited to pizza, toast, fries, vegetables, chicken breasts, and other flatter foods than to tall covered cookware or bulky roasts.
Setup & Ease of Use
- Confirm the renewed unit includes the basket, sheet pan, wire rack, and crumb tray before discarding packaging.
- Check the exterior, door, controls, cord, and accessories for damage before first use.
- Review the current Ninja instructions for rack position, cleaning, and safe flip-up storage.
- Give the oven enough surrounding space for safe operation rather than treating the stored position as the cooking position.
- Avoid running another high-wattage countertop appliance on the same overloaded circuit.
How This Review Was Researched
This review evaluates verified SP151 specifications, current retailer documentation, Amazon Renewed condition guidance, independent toaster-oven testing, and relevant comparison data. No personal hands-on testing is claimed.
Category-Specific Performance
Air Frying & Crisping
Independent RTINGS testing gives the SP151 a solid air-fry result rather than treating its air-fry mode as a label-only feature. In its fries test, 68.9% of the batch was classified as crispy, while 9.3% was overcooked and 21.8% undercooked.
For buyers, that means the wide basket and forced airflow can produce useful crisping, but batch arrangement still matters. It should not be assumed to match a dedicated basket air fryer on every food or load.
Toasting & Everyday Oven Work
The SP151 performs especially well with smaller toast loads: RTINGS measured a 96% evenly browned area in its four-slice test. That makes toast, bagels, reheating, and quick baked foods important strengths for buyers replacing a conventional toaster oven.
Preheat & Temperature Control
RTINGS measured about 1 minute 45 seconds to reach 350°F and strong temperature uniformity across the oven. Fast preheat is useful for weekday cooking because the appliance can become practical for small jobs that may not justify heating a full-size oven.
Capacity & Meal Fit
Ninja lists room for a 12-inch pizza, six slices of bread, six chicken breasts, or up to four pounds of ingredients. Those figures describe a broad cooking surface, but the 7.68-inch exterior height signals the main constraint: wide and shallow is not the same as deep and tall.
Expert Insight
The SP151’s strongest advantage is not simply having eight modes; it is combining a genuinely broad cooking surface with a storage mechanism that changes the idle footprint. That advantage matters most when counter space is the limiting resource.
Key Features Explained
Flip-Up Storage
Ninja states that the oven takes up 50% less counter space when flipped upright for storage. This is most valuable in apartments, RV-style kitchens, and busy counters where a large oven footprint would otherwise remain occupied all day.
OvenCrisp Heating System
The SP151 combines infrared heating with rapidly circulated hot air, using six heating elements across an 85–450°F range. For a broader explanation of why airflow matters, see our guide to how an air fryer cooks food.
Eight Cooking Functions
Air Fry, Roast, Broil, Bake, Pizza, Toast, Bagel, and Dehydrate cover most routine countertop-oven jobs. The practical benefit is appliance consolidation, not proof that every mode outperforms a dedicated specialty appliance.
Real-World Usability & Maintenance
The removable crumb tray and separate basket, pan, and rack simplify routine food-contact cleanup, while Ninja’s retailer support guidance recommends wiping the interior with warm, soapy water and a soft cloth after the unit is unplugged and cool. RTINGS scored the SP151’s cleaning performance at 7.0/10, suggesting maintenance is workable rather than effortless.
The renewed condition changes ownership slightly: Amazon says renewed products are inspected, tested, cleaned, and may arrive in generic packaging with compatible generic accessories. Inventory everything immediately, and use the official online manual if printed documentation is absent.
Pros & Cons
Pros
- Flip-up body reclaims useful counter space.
- Fast preheat for small everyday meals.
- Strong four-slice toasting performance.
- Wide 8-in-1 cooking flexibility.
Cons
- Shallow chamber limits tall foods.
- Interior cleaning is not effortless.
- Renewed units require arrival inspection.
Common Issues & Fixes
Grease or Crumb Buildup
Cause: Frequent high-heat cooking can leave residue inside the shallow oven and on the crumb tray.
Fix: Unplug, cool, remove loose crumbs, and wipe the interior using Ninja’s recommended soft-cloth cleaning approach.
Accessories Differ From New Retail Packaging
Cause: Amazon Renewed products may use generic packaging and compatible accessories depending on the supplier.
Fix: Check every listed accessory immediately and use the return or renewed-guarantee process if the delivered configuration is not as described.
What to Know Before You Buy
First, this is an 1800W appliance, so electrical load matters in older kitchens, RV setups, or circuits already powering another high-draw device. Second, the flip-up feature saves resting footprint but does not eliminate the need for safe clearance while the oven is operating.
Third, the renewed listing should be judged partly on condition and coverage, not only on the base SP151 design. Amazon’s current Renewed guidance says qualifying products are professionally inspected and tested, while many Excellent, Good, or Acceptable renewed purchases have a 90-day return or replacement window; always confirm the terms shown on the live listing.
If you want more context on the standard configuration rather than the refurbished buying decision, read our Ninja Flip SP151 review.

Trade-off: Substantially larger footprint
Is It Worth It?
The renewed SP151 offers its strongest value to buyers who specifically benefit from the flip-up design and broad everyday functions. The trade-off is accepting refurbished-condition variability and a shallow cavity in exchange for a fast, wide cooking surface that becomes less intrusive when stored.
A new conventional toaster oven may make more sense if condition certainty matters most, while the Cuisinart fits buyers wanting traditional oven proportions and the Breville fits buyers prioritizing significantly greater capacity.
Final Verdict
The Ninja Flip SP151 (Renewed) is best suited to small households and space-conscious kitchens that want air frying, toasting, pizza, baking, roasting, broiling, and dehydrating from one appliance. Its most meaningful strength is the combination of proven everyday performance and flip-up storage; its main limitation is the shallow cooking chamber plus the extra inspection step that comes with a renewed purchase.
Choose it when counter space is a high-priority constraint and the delivered condition matches the listing. Consider a larger conventional air fryer toaster oven when vertical capacity, easier access for cleaning, or a brand-new condition matters more.
Frequently Asked Questions
Is the Ninja Flip SP151 a true air fryer?
Yes, it uses forced hot-air circulation for air frying. Independent testing shows meaningful crisping performance, although results still depend on batch size and food arrangement.
How much food fits in the SP151?
Ninja lists capacity for a 12-inch pizza, up to six slices of toast, six chicken breasts, or up to four pounds of ingredients. The oven is wide but shallow, so tall foods are the limiting factor.
What cooking functions does it have?
It has eight modes: Air Fry, Roast, Broil, Bake, Pizza, Toast, Bagel, and Dehydrate. These cover most routine countertop-oven jobs without requiring separate appliances.
What should I check on a renewed SP151?
Check the physical condition, door, controls, cord, basket, sheet pan, wire rack, and crumb tray immediately. Renewed packaging or accessories can differ, so compare the delivered contents with the live listing.
Does the renewed version have the same manufacturer warranty as a new unit?
Do not assume that it does. Renewed coverage is governed by the live seller/Amazon Renewed terms, while new retail SP151 listings commonly show a one-year limited manufacturer warranty.
Is the SP151 good for a small kitchen?
Yes, that is one of its clearest use cases. The oven keeps a wide cooking surface while flipping upright after use to reduce its stored countertop footprint.
