Also, both the models come with two 16 oz. Nutri Ninja to-go cups so you can make smoothies or juices on the go.

But the bl660 has an advantage as it offers a food processing function so you can quickly chop, mince, blend, or grind ingredients depending on your recipes or the meals you want to make.

Weight And Cord Length:

The weight of the BL660 is 7.6 Pounds and the BL621 weighs about 8.07 Pounds making the bl660 blender a little lighter than the bl621 blender.

As for the cord length, the bl660 has a 2 ft length whereas the cord length of the bl621 was not given and I think it will be of the same size.


The voltage required to operate both the ninja blender is 120 volts and don't run these blenders on 220 volts as it will damage the blender.

In terms of construction both the blenders are made from plastic and are dishwasher safe so it is easy to clean and is also BPA-free.

Motor And Blade:

Now about the motor, the BL660 comes with a powerful 1100-watt motor base and the BL621 also has the same 1100-watt powerful motor so in terms of performance, there is no difference.

The total number of blades on both models is 6 and are stainless steel blades so they can crush ice or any other ingredients without any problems and you can make your favorite smoothies, drinks, sauces, etc.

Speed Settings And Other Features:

The Ninja Blender BL660 comes with 3 number of speed settings that are low, medium, or high, along with pulse along and the Bl621 also has 3-speed settings that are low, medium, high as well as a pulse but the bl660 has an upper hand here as it also comes with a single-serve function allowing you to quickly blend the ingredients directly into the cup so you can enjoy smoothies or drinks on the go.

Both also feature pour spouts along with a lock-on lid but the bl621 comes with a non-slip base so the blender doesn't move when you are using it.

Things Included With The Blenders:

The things that come with the BL660 blender are 72 Oz. (64 oz. maximum liquid capacity) Total Crushing Pitcher With Lid, Two 16 oz. To-Go Cups, 2 Spout Lids, 1100-Watt Motor Base, 28 Recipe Inspiration Guide, Pro Extractor Blades Assembly, And Stacked Blade Assembly.

The Ninja BL621 comes with a 72 Oz. Pitcher (maximum liquid capacity is 64 Oz), Two 16 Oz. Cups With Lids, and an 1100 Watt Motor Base.


Above is the complete comparison of both ninja blenders and I think you will be able to pick the right blender without any issues and if you still can't figure it out then I will recommend you to pick the BL660 as it is selling as new whereas the BL621 is sold as renewed so there could be some QC issues.

Also, when buying any one of them be sure to check their prices as the blender may have a price cut and if this article was helpful then kindly share it and have a great day.
