If you’re comparing the Ninja SP101 and the Ninja ST101, you’re not alone—and you’re not wrong to be confused. Ninja uses the word “Flip” in both names, but these two appliances are built for completely different types of cooks and kitchens. I’ve cooked with both extensively, and once you understand what each one is actually designed to replace, the decision becomes much clearer.
Two Different Appliances Hiding Behind the Same “Flip” Name
The Ninja SP101 is a full-featured air fryer toaster oven designed to replace a traditional countertop oven. The Ninja ST101, on the other hand, is a premium slot toaster that happens to bake and broil small items. Treating them as direct competitors is what causes most buying mistakes.
The SP101 flips vertically to save counter space when it’s not being used. The ST101 flips horizontally to change modes—from toaster mode to oven mode. That single distinction affects capacity, cooking style, and who should actually buy each model.

How the “Flip” Feature Actually Works in Real Kitchens
This is the most misunderstood part of the comparison. The Ninja SP101 flips up vertically against the backsplash when you’re done cooking. This saves about half the counter depth, which is incredibly useful in tight kitchens—but it does require clearance above the unit.
The Ninja ST101 flips forward and down. You must flip it down to use bake or broil mode. That means it needs clearance in front, not above. In a narrow galley kitchen or dorm setup, that difference matters.
Ninja SP101 Digital Air Fry Countertop Oven: Real-World Use
The SP101 behaves like a compact oven that just happens to fold away. It includes a dedicated air fry basket, wire rack, sheet pan, and crumb tray. This is not a toaster—it’s a real cooking appliance.
I’ve cooked full sheet pan meals in it: chicken thighs with vegetables, salmon and asparagus, even reheating leftover pizza without soggy crusts. A 13-inch pizza fits comfortably. You can cook up to nine slices of toast at once, which immediately tells you who this machine is built for.
The air fry function is strong enough to replace a standalone basket air fryer for most households. Frozen fries, wings, and even breaded pork chops cook evenly thanks to strong airflow and the included air fry basket.
SP101 Strengths
- True air frying with dedicated basket
- Sheet pan meals are realistic
- Flips up to save counter depth
- High wattage for faster cooking
- Easy back-panel cleaning access
SP101 Limitations
- Needs vertical clearance to flip
- Overkill for single-slice toast needs
- Heavier than it looks
- DIGITAL CRISP CONTROL TECHNOLOGY: Precision-controlled temperature, heat source, and airflow for...

Ninja ST101 Foodi 2-in-1 Flip Toaster: What It Does Best
The ST101 is best thought of as the most advanced slot toaster you can buy. Toast quality is outstanding. Browning is even from front to back, and the extra-wide slots handle artisan bread without tearing or trimming.
When flipped down, the ST101 becomes a compact oven for small items. It’s perfect for reheating pizza slices, baking a single sandwich, or cooking a handful of nuggets. What it cannot do is cook full meals.
You cannot air fry in the traditional sense here. There is no air fry basket, and airflow is designed for small, quick items—not full trays.
ST101 Strengths
- Exceptional toast quality
- Minimal counter footprint
- Fast heat-up with no preheat
- Simple crumb tray cleaning
- Ideal for small kitchens
ST101 Limitations
- No true air fry mode
- Cannot cook sheet pan meals
- Very limited capacity
- 2-IN-1 FLIP FUNCTIONALITY: Toaster and Compact Toaster Oven in one small footprint. Flip up for...
- PERFECT TOAST: More even toasting vs. a traditional toaster based on front to back evenness, in one...
- VERSATILE FUNCTIONS: Choose from the Toast, Bagel, Defrost, Bake, Broil, and Reheat functions.
Capacity Comparison: This Is Where the Choice Is Decided
| Cooking Task | SP101 | ST101 |
|---|---|---|
| Frozen pizza | 13-inch | 8-inch max |
| Toast | Up to 9 slices | 2 slices |
| Chicken breasts | 6 at once | Not practical |
| Sheet pan meal | Yes | No |
Cleaning and Maintenance Differences
The SP101 opens from the back for deep cleaning. Grease buildup is easy to access if you air fry often. The ST101 relies on a traditional crumb tray system, which is faster but less thorough.
If you cook greasy foods frequently, the SP101 is easier to keep clean long-term. If you mostly toast and reheat, the ST101 is simpler.
Which One Should You Actually Buy?
Buy the Ninja SP101 if you want to air fry chicken, cook full meals, replace a toaster oven, or feed more than one person regularly.
Buy the Ninja ST101 if your priority is excellent toast, quick breakfasts, and compact size—and you don’t need to cook full dinners in it.
Final Thoughts
The Ninja SP101 and ST101 are not rivals—they’re solutions for different kitchens. Once you stop asking which one is “better” and start asking which one matches how you actually cook, the right choice becomes obvious.
