Ninja SP151 Flip Toaster Oven & Air Fryer

The kitchen appliance market is always growing, and companies are trying to create products that can solve several problems at once. Being also passionate about cooking but having scarce counter space. I have always been suspicious of the so-called ‘multi-function’ appliances that claim to be all things in one but are average in all of them. When I first heard about the Ninja SP151 Flip Toaster Oven & Air Fryer with its flipping mechanism, I was hooked but also leery.

Could one device actually work well as both a toaster and an air fryer oven? It’s been three months of testing it in my everyday cooking and I am prepared to give my final verdict on whether or not this innovative appliance deserves a place in your kitchen.

Design Innovation: The Flip That Changes Everything

Pros	Cons
Saves Counter Space – Flips up and stores away neatly. Cooks Meals Faster – Prepares food in just 20 minutes. Healthier Air Frying – Uses up to 75% less fat.	Limited Cooking Height – Doesn’t fit deep pans. Manual Cleaning Needed – No self-cleaning option. No Interior Lighting – Harder to monitor food.

The Ninja SP151 features a unique design that allows it to switch between two configurations. Unlike conventional toaster ovens, which have a fixed setup, this appliance can be positioned vertically in “toaster mode” to save counter space.

With a press of a button and a flip, it transitions to “oven mode”, unlocking its full capabilities for air frying, baking, and roasting. This smart design isn’t just clever engineering—it’s a practical solution for kitchen storage challenges. The stainless steel body gives it a sleek, professional look that complements most kitchens, while the digital display makes setting and monitoring cooking parameters effortless.

In toaster mode, it measures 19.7″ L × 15″ W × 7.5″ H, taking up no more space than a couple of small appliances while offering superior functionality.

Right out of the box, the Ninja Flip feels solid and well-built. Weighing around 22 pounds, it’s sturdy enough to prevent tipping. The door opens smoothly, and the clicky control buttons provide satisfying feedback.

The flip mechanism, which might seem like a potential weak point, is impressively durable and designed to last.

Eight Functions in One: Versatility Without Compromise

The SP151 isn’t just marketing hype—it truly delivers on its 8-in-1 functionality. Here’s how each feature performs in real-world cooking:

• Air Fry: This function rivals dedicated air fryers, producing crispy exteriors with minimal oil. Whether making fries, wings, or breaded veggies, results are consistently crisp with no sogginess.
• Air Roast: By combining intense heat and fast air circulation, this function roasts food up to 30% faster than a conventional oven. Small chickens, pork tenderloins, and roasted veggies turn out crispy outside and juicy inside.
• Bake: Unlike many countertop ovens, the SP151 bakes evenly, eliminating hot spots. Cookies, muffins, and small cakes come out with consistent results, and precise temperature control benefits delicate baking.
• Broil: Its top-down heat crisps and browns food effectively—ideal for finishing casseroles, melting cheese, or caramelizing proteins. The upper heating element ensures results comparable to full-sized ovens.
• Toast: With seven shade settings, it evenly toasts both sides at once, eliminating the need to flip and re-toast.
• Bagel: Specially designed to toast the cut side while gently warming the exterior. Wide slots accommodate even thick, artisanal bagels.
• Dehydrate: The low-temperature setting removes moisture efficiently, making fruit chips, jerky, and dried herbs with ease.
• Keep Warm: Keeps food at serving temperature (around 150°F) without overcooking—perfect for managing meal timing.

Beyond these individual functions, the SP151 allows creative cooking combinations, like air roasting followed by broiling, expanding its versatility even further.

Performance That Impresses

The Ninja SP151 is driven by a 1800 watt heating system that delivers good performance through out its functions. The digital thermostat controls the temperature between 150°F and 450°F with pretty good accuracy. I checked it with an oven thermometer and it stays within 5° of the set temperature which is better than some full sized ovens.

The rapid preheat feature can reach cooking temperature in approximately 60 seconds which is a lot faster than conventional ovens which can take 10-15 minutes to heat up. The only major drawback is the size. Although the oven can fit a 12-inch pizza, a 4 lb. chicken, or 6 slices of toast, it is obvious that it cannot replace a full sized oven for large family gatherings or for preparing large batches of food. But for households of 1-4 people, it is sufficient for everyday cooking.

User Experience: Thoughtful Controls and Features

The control interface is quite simple yet very easy to use and understand. The digital display is also very convenient as it shows the function, temperature and time remaining in the cook cycle. The buttons are well thought out and are clearly distinguished with dedicated presets for various foods that set the cooking parameters accordingly.

At first, the flip mechanism seemed complicated, but it turned out to be quite easy to use – a simple button release does the job. The motion becomes rather natural and easy after using it a few times. The unit stays locked firmly in both positions and there is no way it can be unstable during use.

The timer settings are quite versatile, with most functions being able to be set for up to 60 minutes and dehydrating having the ability to be set for up to 12 hours. It gives a beep when it is ready for preheating and when the cooking time is done, it turns itself off to avoid overcooking, a feature I value a lot when I am busy in the kitchen.

Some accessories come with the product which increase the productivity of the appliance. The air fryer basket is the perfect size for the cavity and has a non-stick coating so that the food will not stick. The sheet pan is solid and practical and can be used for everything from cookies to vegetables for roasting. Both accessories can be placed in the dishwasher, which makes the cleaning process much easier.

Cleanup: Surprisingly Effortless

One of the greatest advantages of the SP151 over many other products is the ease of cleaning. The non-stick interior is easy to wipe clean, and the crumb tray is removable, which collects any debris. All of the removable parts, such as the air fryer basket, sheet pan, and wire rack are coated with Teflon and are safe to wash in the dishwasher.

This is a huge improvement from traditional toaster ovens in which it can take a lot of scrubbing to remove baked on residue. The flip functionality is also useful for cleaning because you can arrange the unit so that you can get to various interior parts more easily. The door is not detachable but it opens quite wide to allow access to the inside without a hitch.

The maintenance is quite low. It is suggested to clean the product regularly and check the seal around the door to make sure that it is intact. Besides these two basic measures, there is no need for much maintenance, which is a big plus, given that many appliances have complicated filtration or many parts that are difficult to clean.

Value Consideration: Investment Analysis

With a retail price of approximately $280 (though sales and promotions can reduce this), the Ninja SP151 represents a significant investment compared to basic toaster ovens or standalone air fryers. However, when evaluated as a replacement for multiple appliances, a toaster, air fryer, and countertop oven, the value proposition becomes more compelling.

The construction quality suggests durability for years of regular use. The one-year warranty provides some reassurance regarding the investment, though given the build quality, I would expect the unit to function well beyond this period with proper care.

When analyzed on a cost-per-use basis, the SP151 proves economical for frequent cooks. I find myself using it multiple times daily, for morning toast, lunch preparation, and dinner components. It also consumes less energy than heating a full-sized oven for smaller cooking tasks, potentially providing ongoing utility savings.

For households with limited counter space, the space-saving design adds substantial value. The ability to flip between configurations means you’re not dedicating permanent counter real estate to appliances that might see only occasional use.

Practical Considerations and Limitations

While my experience with the SP151 has been predominantly positive, it’s important to acknowledge some limitations. The learning curve, while not steep, does require some adjustment, particularly when determining optimal cooking times and temperatures for favorite recipes.

The flip mechanism, though well-engineered, necessitates sufficient clearance above the unit when in toaster mode. This may present challenges in kitchens with low-hanging cabinets over countertops.

The capacity, while adequate for most everyday cooking needs, won’t replace a full-sized oven for large gatherings or extensive batch cooking. This is an inherent limitation of any countertop appliance and should be considered based on your typical cooking patterns.

The unit does generate some fan noise during air frying and air roasting functions, though it’s comparable to or quieter than standalone air fryers. The noise level isn’t disruptive in most kitchen environments but is worth noting.

Finally, the multi-functionality means that if one component fails, multiple cooking capabilities could be affected. However, the robust construction and quality components suggest this should not be a frequent concern.

Conclusion: A Versatile Kitchen Game-Changer

After three months of using it for extended periods, I have come to consider the Ninja SP151 Flip Toaster Oven & Air Fryer as a must-have appliance in my cooking routine. The flipping concept has been used to solve the problem of limited counter space and it has done so successfully without compromising on the functionality or efficiency of the appliance.

Although it does take some time to get used to how to use it to the fullest and the capacity is not enough to replace a full-sized oven for cooking in large quantities, these are relatively small issues when compared to the advantages of the device and the quality of the results it provides. For home cooks in search of ways to simplify their kitchen without diminishing the available cooking options, the SP151 is a well-conceived answer to that problem.

In a market full of kitchen gadgets that are useful in theory but not in practice, this appliance is a welcome addition – it is a genuinely innovative product that solves real problems and does it well when it comes to all the functions that it offers. From air frying your snacks, to baking cookies, to toasting your morning bread, the Ninja SP151 does everything efficiently, making it a worth investment for small and stylish kitchens that require appliances to fill different cooking needs.

Frequently Asked Questions

1. How much counter space does the Ninja SP151 actually save compared to having separate appliances?

The Ninja SP151 measures approximately 19.7″ × 15″ × 7.5″ in its toaster position. Compared to having separate toaster and air fryer units (which together might occupy around 22″ × 16″ of counter space), you’re saving roughly 25-30% of valuable counter area. The vertical orientation in toaster mode is particularly advantageous, utilizing height rather than horizontal counter space.

2. Can the Ninja SP151 replace my microwave for reheating leftovers?

For many foods, yes—and often with better results. The SP151 excels at reheating pizza, fried foods, and baked goods, maintaining crispness that microwaves destroy. However, it does take longer (3-4 minutes versus 30 seconds) and isn’t practical for liquids or very moist foods. I find myself using both appliances for different reheating scenarios, depending on the food type and time constraints.

3. How difficult is it to clean if something spills or splatters inside the oven?

The non-stick interior makes cleaning surprisingly straightforward. For most spills, waiting until the unit cools and then wiping with a damp cloth removes residue effectively. For stubborn spots, a paste of baking soda and water works well. The removable crumb tray catches most drips, preventing them from burning onto the heating elements. The most challenging areas are around the upper heating elements, but these can be carefully cleaned with a soft brush.

4. Is the flipping mechanism durable, or likely to become problematic with regular use?

After three months of flipping the unit multiple times daily, I haven’t noticed any degradation in the mechanism’s operation or stability. The components appear to be made of high-quality materials, and the locking system engages securely in both positions. While only extended use will reveal long-term durability, the design appears well-engineered for repeated operation over many years.

5. How does the energy consumption compare to using a full-sized oven?

The Ninja SP151 uses approximately 1800 watts during operation, compared to most full-sized electric ovens that consume between 2000-5000 watts. Beyond the lower wattage, the smaller cavity heats up much faster and requires less energy to maintain temperature. For small to medium cooking tasks, it’s significantly more energy-efficient. Based on my utility rates and usage patterns, I estimate saving approximately $15-20 monthly by using the SP151 instead of my full-sized oven for daily cooking needs.
