Are you trying to decide if you should buy the Ninja BL660 or the BL621? On the surface, both these blenders look alike, so it’s understandable if you’re uncertain.
However, we’re here to help you make your decision. In this comparison, we’ll be putting the BL660 and the BL621 against each other, digging into their similarities and differences. At the end, we’ll also discuss how you can decide between them.
Ninja BL660 vs BL621 Summary
The Ninja BL660 is representative of how high-quality the standard Ninja blender can be. It has a robust 1100-watt motor that can handle the hardest ingredients and a massive 72-ounce pitcher designed to handle your biggest batches. However, it also has the finesse and flexibility to make personal portions with its included to-go cups.
It seems as if the Ninja BL621 is sort of an earlier version of the BL660. As such, it has remarkably similar features. The greatest difference is its Nutrient Extraction mode, which is designed to pull the vitamins and nutrients out of fruits or veggies. Another thing worth noting is that you can pretty much only find it used or renewed these days.
While you can usually trust in the quality of a renewed blender like the BL621, we personally say you should go for the BL660. You get features that are pretty much identical to the BL621’s, with the added benefit that it’s brand-new.
Because it’s still actively produced, you’re also more likely to find replacement parts for the BL660 if you ever end up needing them.

If the bottom line for you when it comes to blenders is sheer blending power, you’ll be hard-pressed to choose between the BL621 and BL660. They both have 1100-watt motors.
This amount of power is more than enough for the average person. With either blender, you’ll find the capability to pulverize even notoriously tough things like ice.
Stacked Blade Assembly
The famous Ninja stacked blade design is used in the BL621 and BL660. You can tell just by looking at them; their blades circle a tower that goes up the middle of the jar.
These stacked blades are perfect for making short work of your ingredients. Because they reach further up into the jar, they can thoroughly blend your mixtures, leaving no stray pieces behind.
It’s not surprising that blenders can get a little bit messy. With all the foods being flung around inside them, ingredients tend to get stuck in the corners and under sharp blades.
If you’re worried about having to spend extended periods of time trying to clean them out, you can breathe a sigh of relief here because they’re simple to maintain. As the blending jars and cups are dishwasher-friendly, you can just put them in your dishwasher for a cycle to clean them.
To-Go Cups and Lids
You don’t always have enough time in the day to sit around at home sipping on a smoothie. For those times when you’re in a rush and need to take your drinks on the go, the BL660 and BL621 each have portable cups.
For either blender, you can blend a mixture directly into these cups and then screw a sip lid on them. This instantly turns your creation into a portable one so you can take it wherever you go.
The added benefit to this is that it could also prevent spills. Even if you’re not planning to go anywhere, you could use the cup simply as an extra measure of protection around the house.
Manual Blend Settings
While the labels on their buttons are different, the BL660 and BL621 have essentially the same manual functions: low, medium, high, and pulse.
On the BL621, they’re actually labelled that way. The BL660, on the other hand, has them labelled as one, two, three, and pulse respectively.
Regardless, the function is the same. You’ll get complete control over the intensity of the blend with either the BL660 or BL621.
Blending Pitcher Capacity
Both these Ninja blenders include an extra-large blending pitcher with a 72-ounce capacity. This is ideal for when you need to serve a group of people.
With the size of these blending jars, no one will ever be left out. You’ll be able to make enough frozen drinks, smoothies, or dip for everyone.
If you don’t have a lot of space on your counters, you’re probably planning on putting your blender away in between uses. On some electronics, this can be a nuisance, especially when their cords just get in the way.
The BL660 and BL621 both make storage a snap. With their built-in cord wraps, you can tuck the cords into the bases and put the whole thing away.
Ninja BL621 Nutrient Extraction Setting
There’s really only one difference between the Ninja BL660 and BL621: the BL621’s nutrient extraction setting. The setting is designed for use with the single-serve cups and extracts the nutrition from your fruits and veggies.
If you look at the BL660, you’ll see that this button is now called “Single Serve” instead. Ultimately, you can use them to achieve the same thing: pulling nutrients out of your healthy ingredients.
Which One Should You Buy?
With the BL660 and the BL621, the similarities are more than just superficial. Truthfully, there isn’t much of a difference between them.
In fact, the only real difference is the labelling on the Single-Serve button. The BL621 has it labeled as Nutrient and Vitamin Extraction, while the BL660 simply has it called Single Serve.
Of course, there’s also the difference between the manual setting labels; the BL660 uses numbers, while the BL621 calls them low, medium, and high. However, in all other aspects, these blenders are the same. What you can use one for, you can also easily use the other for.
Nonetheless, we do recommend the BL660 in this comparison. The reason we’re suggesting it is that it’s still in active production, while you can generally only get the BL621 renewed. With the BL660, you can easily get a new one if that’s what you want.
