Some appliances quietly sit on the countertop and rarely get used, while others end up becoming the heart of the kitchen. For me, blenders fall into that second category. I rely on them for everything from morning smoothies to weekend frozen cocktails and even the occasional soup.
That’s why I recently tested two very similar models from Ninja—the BN751 Professional Plus DUO Blender and the DB751A Pro Plus DUO Blender. At first glance, they look nearly identical, but small differences in design, features, and performance make them worth comparing in detail.
Key Difference Between Ninja BN751 vs DB751A Blender
The Ninja BN751 emphasizes convenience with its recipe guide and slightly lighter design, making it perfect for families who want quick, fuss-free blending. On the other hand, the DB751A comes across as a sturdier, upgraded version with a stainless accent design and a more professional feel. While both share the same 1400-watt power base and Auto-iQ programs, the DB751A feels like it’s tuned for heavier, frequent use.

Detailed Comparative Review
Design and Build Quality
The BN751 has the modern Ninja look—sleek, all-black, with a slightly taller profile. It feels sturdy but does lean a little bulkier on the counter. The DB751A, however, immediately stands out with its black and stainless finish. It’s a touch more elegant, fitting better in a contemporary kitchen. While both are plastic at the core, the DB751A looks more premium, which matters if you like leaving appliances out on display.

Ease of Use
Operating either model is straightforward thanks to the Auto-iQ technology. With one button press, you can walk away while the blender handles pulsing, pausing, and blending on its own. In my tests, the BN751’s recipe guide made it easy to jump in with new drink ideas, while the DB751A skipped that but gave me the same intuitive controls.
The lids and locking mechanism on both models feel solid. Cleaning is equally simple—just rinse the blade assembly and toss the cups and pitcher into the dishwasher. The only thing I noticed is that the BN751 is slightly heavier to lift around, while the DB751A feels easier to maneuver.
Performance and Functions
Both blenders come with 1400 watts of peak power, which is more than enough for crushing ice, blending fibrous greens, or pulverizing frozen fruit. The Total Crushing Blades on the BN751 are aggressive, leaving me with smooth results in seconds. The DB751A’s Pro Stainless Blades performed just as well but felt slightly more efficient at handling denser mixtures like nut butters.
In terms of presets, both blenders give you 3 Auto-iQ modes—Smoothies, Frozen Drinks, and Nutrient Extractions. The performance was consistent across both, though I found the DB751A slightly less noisy during long blending sessions.

Capacity and Versatility
The 72-oz pitcher is identical on both and is perfect for family-sized batches. On mornings when I only wanted something for myself, I used the 24-oz single-serve cups—a lifesaver when heading out the door. If you’re someone who alternates between solo drinks and family batches, either model works perfectly.
Everyday Experience
Here’s where subtle differences matter. The BN751, with its recipe book and slightly heavier frame, feels like the “starter-friendly” option—it encourages experimentation. The DB751A, meanwhile, feels like the model you graduate to when you know what you want from your blender: power, sleekness, and reliability.

Conclusion and Recommendation:
After testing both models side by side, I realized this is less about performance and more about preference. Both the Ninja BN751 and DB751A deliver excellent blending power, versatile functions, and convenient on-the-go options.
If you’re looking for a beginner-friendly blender that encourages you to try new recipes and want that little bit of extra guidance, go with the BN751. On the other hand, if you already know your way around a blender and prefer a sleeker, more professional-looking appliance that handles frequent use with style, the DB751A is the better choice.
Personally, I’d lean toward the DB751A for its lighter build and premium finish. It feels like the more future-proof option, especially if your blender stays out on the counter all the time. But whichever you choose, both are powerful, versatile machines that can transform your kitchen routine.
