Nutri Ninja to-go cups on the other hand the bn751 comes with two single-serve cups having a capacity of 24 Oz with spout lids and with these to-go cups you can make smoothies as well as juices on the go.

But the bl660 has an upper hand here as it features a food processing function so you can quickly chop, mince, blend, or grind ingredients according to your recipes.


In order to operate both the blenders, you will need to provide them with 120 volts, and don't run this blender on higher voltage as it will damage these models.

Weight And Cord Length:

As for the weight, the ninja bl660 weighs about 7.6 pounds and I wasn't able to find the weight of the ninja bn751 but I think it will have the same weight or maybe a little heavier than the bl660.

The cord length of bl660 is 24 inches (2 Feet) whereas the cord length of bn751 was not found.

Both models have a plastic construction and both blender blades, single serve cups, and lids, are dishwasher safe so cleaning is easy to do and they are also BPA-free which is a nice thing.

Motor And Blade:

In terms of performance, the BL660 blenders come with an 1100-watt motor while the BN751 has a powerful 1400-watt motor so if you prefer more power then the bn751 is a nice choice.

As for the blade, both have the same 6 total crushing blades allowing you to blend different ingredients, juices, drinks, or crush ice easily.

Speed Settings And Other Features:

BL660 blender comes with 3-speed settings which are low, medium, or high, pulse along with an extra feature that is a single-serve function by which you can quickly blend the ingredients directly into the cup.

But BN751 has an edge over here as it not only comes with 3-speed settings that are low, medium, and high along with a pulse feature but it also comes with 3 Auto IQ Presets Function for smoothies, frozen drinks, and nutrient extractions which can be used by simply pressing the button.

Both the models have a lock-on lid along with a pour spout but the bn751 comes with an easy-to-use digital display.
