It also runs on 1,550 watts, making it quite energy efficient. The Ninja AF101 model’s temperature range (105 to 400 degrees Fahrenheit) is typical of most air fryers in our reviews. And like most others in our reviews, this model comes with dishwasher-safe accessories, a one-year warranty, and a recipe book. However, the capacity is only 4 liters, which is less than many other units in our reviews. It also only has four presets and functions and does not have a broil function. In addition, the two 4-quart air fryers that perform better than the Ninja model-the Cosori Smart Wi-Fi Air Fryer and the Instant Vortex Plus Air Fryer-are priced similarly to the Ninja model, which may make them a better choice for budget-conscious buyers. The Ninja AF101 hot air fryer circulates very hot air around food to remove moisture, giving the food a crispy, deep-fried texture. Because cooking uses very little oil, foods can contain up to 75% less fat than traditional frying methods. When cooking, you can choose from four one-touch cooking functions. You can also manually set the cooking time and temperature. The unit has a temperature range of 105 to 400 degrees Fahrenheit, so you can slowly remove moisture from foods or crisp them up with high heat. The Ninja AF101 can not only fry, but also roast, reheat and dehydrate. However, it cannot grill or be used as a pressure cooker. The Ninja AF101 air fryer features a 4-quart air fry basket and a crisping plate with ceramic-coated non-stick surface. The unit comes with an “inspiration guide” with 20 recipes. Preset buttons on the front of the unit include fry, broil, reheat and dehydrate functions. When you purchase this unit, you also get a 60-day money back guarantee and a one-year warranty.
