Equipped with a 1200-watt motor, this blender promises to crush ice, blend frozen fruits, and handle tough ingredients effortlessly. Its ability to make smoothies, frozen drinks, sauces, and more has earned it a reputation as a versatile and reliable appliance. In this review, we’ll dive into the Ninja BL642’s performance, design, ease of use, noise level, cleaning, and overall value to determine if it’s the right choice for your kitchen.
Performance and Power
One of the standout features of the Ninja BL642 Nutri Ninja is its impressive 1200-watt motor. This high-powered motor ensures that the blender can handle tough ingredients with ease, from whole fruits and vegetables to ice and seeds. Many customers are impressed by its ability to pulverize ice into snow-like consistency within seconds, creating smooth frozen drinks and smoothies.
The Pro Extractor Blades are designed to break down entire fruits and vegetables, including tough seeds and skins. This allows for maximum nutrient extraction, ensuring that you get the most out of your ingredients. Whether you’re blending leafy greens, frozen berries, or protein-packed smoothies, the Ninja BL642 makes sure you get smooth, well-blended results every time. Many customers report that the blender provides a creamy texture, which is often a challenge for other blenders, especially when blending ingredients like leafy greens or fibrous vegetables.
In addition to making smoothies and frozen drinks, the powerful motor allows for versatility in other recipes, such as sauces and soups. The blender’s performance is consistent across a variety of tasks, making it a reliable option for anyone looking for an all-in-one appliance.
Auto-IQ Technology

Another impressive feature of the Ninja BL642 Nutri Ninja is its Auto-IQ technology. This intelligent system takes the guesswork out of blending by using unique timed pulsing, blending, and pausing patterns. Auto-IQ combines these patterns to optimize blending results for various ingredients, making it incredibly easy to use. Whether you’re making smoothies, frozen drinks, or nutrient extractions, the blender automatically adjusts to the perfect speed and timing, providing the best results every time.
Customers find the Auto-IQ function extremely convenient. It eliminates the need for constant monitoring or adjusting settings, which is especially helpful for busy individuals who want quick, easy results. The preset programs, including those for smoothies, frozen drinks, and nutrient extraction, are tailored to specific tasks, making the process hands-off and simple.
Capacity and Versatility
The Ninja BL642 is built for both personal and family use. It comes with a 72-ounce Total Crushing Pitcher, which is perfect for making large batches of smoothies or frozen drinks for the whole family. The pitcher’s 64-ounce max liquid capacity means you can easily blend multiple servings at once without needing to do multiple rounds. Customers love the pitcher’s size and versatility, particularly when making large batches for family gatherings or meal prep.
For those who prefer single servings or want the convenience of blending on the go, the Ninja BL642 includes three different-sized To-Go cups: 18 oz, 24 oz, and 32 oz. These cups come with spout lids, making it easy to blend your ingredients, attach a lid, and take your drink with you. Whether you’re preparing a quick breakfast smoothie or an afternoon snack, these cups allow for a convenient, portable solution. The ability to blend directly into the cups is a big plus for many customers, as it eliminates the need to transfer your drink into another container.
The inclusion of multiple cup sizes also enhances the blender’s versatility, allowing it to cater to both large and small batch needs. This combination of a large pitcher and three single-serve cups makes the Ninja BL642 an ideal choice for individuals, families, and anyone in between.
Ease of Use
The Ninja BL642 is designed to be user-friendly, making it easy for anyone to use, regardless of experience. The controls are simple and intuitive, with a large power button and separate buttons for the Auto-IQ functions. Simply add your ingredients, choose your cup size, and press a button to let the Auto-IQ technology do the work. The blender’s straightforward design ensures that blending is quick and easy.
The blender’s versatility also extends to its different attachments. The Total Crushing Pitcher, food processor bowl, and To-Go cups are all easy to assemble and disassemble, allowing you to switch between tasks with minimal effort. The included recipe guide provides helpful inspiration for smoothies, frozen drinks, sauces, and more, so you can get the most out of your blender.
Cleaning and Maintenance
Cleaning the Ninja BL642 Nutri Ninja is easy, thanks to its dishwasher-safe parts. The Total Crushing Pitcher, To-Go cups, and lids are all BPA-free and can be placed on the top rack of your dishwasher for quick cleaning. Many customers appreciate how easy the blender is to clean, as the parts are designed to be taken apart easily without any hassle. After blending, you can simply rinse the cups and lids or toss them in the dishwasher, saving you time and effort.
For hand cleaning, the parts can be easily rinsed with warm water and dish soap. The Pro Extractor Blades, however, need to be handled with care, as they are sharp. Wiping down the motor base is all that’s needed to maintain its appearance and functionality. Overall, the cleaning process is simple and quick, making this blender a convenient option for regular use.
Noise Level
While the Ninja BL642 is a powerful blender, some customers have mentioned that it can be a bit loud, especially when blending frozen ingredients or crushing ice. The 1200-watt motor provides ample power, but the noise level can be noticeable during operation. This is common with high-powered blenders, and while the noise is not excessive, it may be a consideration for those who need a quieter appliance.
For most users, the noise level is manageable, particularly because the blender operates efficiently and quickly. However, if noise is a concern for you—especially if you need to blend early in the morning or in a shared living space—it’s something to keep in mind.
Value for Money
The Ninja BL642 Nutri Ninja is a great value for its price. It offers powerful performance with a 1200-watt motor, Auto-IQ technology, and multiple blending options, including a large pitcher and several To-Go cups. The fact that it includes all the accessories you need, such as spout lids, a recipe guide, and a food processor bowl, makes it an excellent all-in-one appliance for both blending and food prep.
At its price point, the Ninja BL642 provides excellent performance compared to other blenders on the market. It combines power, versatility, and ease of use, making it a solid investment for anyone in need of a high-quality blender for smoothies, frozen drinks, and more.
Customer Feedback and Satisfaction
Overall, customer feedback for the Ninja BL642 is positive. Many users rave about its power, performance, and ease of use. The Auto-IQ technology makes blending simple and efficient, while the versatility of the multiple To-Go cups and large pitcher adds great value. Customers particularly appreciate the blender’s ability to make smoothies and frozen drinks quickly and with smooth consistency.
However, some customers have mentioned concerns about the blender’s noise level and durability. While the noise is not extreme, it may be a concern for some users. Additionally, there are mixed reviews regarding the build quality, with some customers feeling that the plastic parts may not hold up well over time. Despite these issues, the overall feedback is overwhelmingly positive, and many users find the Ninja BL642 to be a reliable and effective blender.
