Ninja SP101 vs. SP151: Which Air Fryer Toaster Oven Wins for 2026?

Price — SP151 wins on budget

SP151 costs $75 less than SP101. With similar features and identical functions, the SP151 delivers most of the same capabilities at a significantly lower price. For budget-conscious shoppers, that makes it the clear value pick.

SP101's $235 price tag buys extra capacity. If you cook for a family or entertain often, the larger interior justifies the premium. The per-meal cost difference quickly narrows if you use it daily.

Capacity — SP101 wins for large meals

SP101 offers 45% more usable pan area. It fits a 13" pizza, up to 9 slices of toast, or 6 chicken breasts. The SP151 maxes out at a 12" pizza and 6 slices of toast.

For a single person or couple, SP151's capacity is enough. A 12" pizza and 4 chicken breasts still handle weeknight dinners. But if you frequently cook for four or more, the SP101's extra room prevents batch cooking.

Door Style — Side-swing vs Dropdown

SP151's side-swing door is easier in tight spaces. It opens to the right, so you can place it flush against a left wall. The SP101's dropdown door needs about 19 inches of clearance in front.

SP101's dropdown door doubles as a landing surface. When open, it can hold a hot pan temporarily. But it blocks access to lower cabinets. Choose based on your kitchen layout.

Wattage & Cooking Speed

SP151 has slightly more power (1800W vs 1750W). Both claim faster cooking than a traditional oven — up to 60% faster for SP101, 50% for SP151. In practice, preheat is under 60 seconds for both.

The 50W difference is negligible in real use. Both models heat up quickly and maintain temperature well. Neither will significantly outperform the other on cooking time.

Air Fry Quality

Both use infrared heat and rapid air circulation. The SP151 uses OvenCrisp Technology; the SP101 uses Digital Crisp Control. Both claim up to 75% less fat than deep frying. User reviews consistently praise the air fry performance of both models.

For crispy results, either model delivers. The SP101's larger basket handles more food at once — ideal for feeding a crowd. The SP151 is fine for 2-4 servings.

Ease of Cleaning

Both include a removable crumb tray. The SP101 also has an accessible back panel for deep cleaning. The SP151's tray slides out from the front. Both are non-stick coated for easy wipe-down.

SP101's larger interior means more surface area to clean. If you cook messy foods often, the SP151's smaller cavity is quicker to maintain.

Counter Space & Storage

Both flip up to save 50% counter space. When not in use, you can store them vertically against the backsplash. This is a standout feature shared by both models — rare among toaster ovens.

SP101 is deeper at 19.72" vs SP151's 17.01". The SP151 fits on shallower counters more easily. Measure your counter depth before choosing.

Energy Efficiency

SP151 claims 80% more efficient than a full-size oven. SP101 doesn't provide a percentage, but both use less energy than a conventional oven. For daily use, the SP151's lower wattage (150W less max) may save pennies per use — not a deciding factor.
