The Nutri Ninja Duo delivers the power of Ninja blenders but with the convenience of multiple pitchers, including a large traditional one and portable ones that you can drink right out of. The main pitcher is a whopping 72 ounces, more than the typical competitor. The portable ones in the BL642Z include two 24-ounce cups and one 32-ounce once, each with Sip & Seal Lids. Opting for the BL642 Nutri Ninja Duo instead swaps one of the 24-ounce cups for an 18-ounce one. TheĀ blenderĀ as a whole is 7 by 10 by 17.5 inches, surprisingly small considering the range of uses for this machine.

This blender costs about $245, which is a reasonable price given its power and the fact that you get a total of four pitchers/cups to blend using, eliminating the need to do dishes as often. The Nutri Ninja Blender Duo also comes with a few unique features to set it apart, including the Auto-iQ technology for smart blending programs.

Features of the Nutri Ninja Duo Blender

The Nutri Ninja Blender Duo comes with Total Crushing Stacked Blades, which Ninja designed to maximize the ability to crush any ingredient, particularly frozen items. To further its ability to chop and blend ingredients, the appliance also has a Pro Extractor Blades Assembly. Those blades break down full vegetables and fruits as well as seeds to maximize the extraction of vitamins and nutrients. The pitcher was designed with the same goal in mind and is officially called the 72-ounce Total Crushing Pitcher. This blender has a 1,200 motor, which is a very good amount of power, although some blenders do have more.

The Auto-iQ technology is one of the strong selling points of the Nutri Ninja Duo as it includes intelligent timed blending programs that let you just press a button instead of worrying about the ideal blending cycle. This feature can even automatically turn the blender back on. While Auto-iQ takes some getting used to, it is incredibly useful once mastered. The other big selling point is the Nutri Ninja Cups, the 24- and 32-ounce Tritan cups that you can blend drinks in. These come with Spout Lids and let you easily bring your drink with you wherever you go.

The electronic controls on the base of this Ninja blender are intuitive to use. There is even a dedicated button for ice. The controls are flat for easy cleaning as well. When using the blender, it is also quieter than many of the competitors, although it is not the quietest model available. The base of the Nutri Ninja Duo really helps it stand out as it is non-slip, allowing for convenience as well as safety. It even includes suction cups on the base so tipping over is not an issue. The cord wrap is perfect for storage.

The Nutri Ninja Blender Duo is particularly useful for those who enjoy smoothies on a regular basis and want to be able to blend them in the same container that they will drink out of. The additional cups that can be used for blending were specifically designed for this purpose and excel at it. Thanks to the size and other features of this Ninja blender, it also excels at most other tasks you would expect from a blender.

The Nutri Ninja Blender Duo is a bit expensive, but most people who own it agree that it offers a good value. Part of this comes from the numerous features, like Auto-iQ technology, while another aspect of its value is the range of blending cups plus the pitcher. The warranty is just a year, which is on the lower end of average, but still reasonable.


The Nutri Ninja Blender Duo provides an excellent value for those who regularly make smoothies and want to take advantage of the multiple Nutri Cups that come with it. Those are incredibly useful and since there are three included along with the main pitcher, you can prep smoothies ahead of time. The only thing hurting the value of this blender is its lackluster one-year warranty, which is just average. Otherwise, the 1,200 watts of power, Auto-iQ technology, and included cups make it certainly worth the price.

The technology of the blender also helps it stand out in terms of crushing ingredients. Between the Total Crushing Stacked Blades, the Pro Extractor Blades, and the Total Crushing Pitcher, the Nutri Ninja Duo makes it simple to blend smoothies that maintain the vitamins and nutrients and have your desired consistency. Overall, this is an excellent choice for those who cannot choose between a traditional blender with a large pitcher or one with a single-serving design. It should definitely be in your consideration if you want a powerful blender that offers both options.
