Functionality and Versatility

The Nin­ja (BN401) Nutri Pro Per­son­al Blender per­forms very well on many tasks. It pul­ver­izes most of the ingre­di­ents into a smooth con­sis­ten­cy, with no chunks and pieces.

Smooth­ie: This blender makes almost per­fect qual­i­ty smooth­ies from soft and hard food, though the car­rots will come out just a lit­tle tex­tured. It also works very well on many leafy ingre­di­ents such as raw spinach or kale and makes a good qual­i­ty, smooth drink with only small green bits. It dec­i­mates raw nuts and seeds very well in smooth­ies with­out any notice­able bits. The only prob­lem it has with rasp­ber­ry and black­ber­ry seeds is that this Nutri Nin­ja does not break them down well, and often a sec­ond cycle is need­ed to get the accept­able con­sis­ten­cy with the berry seeds.

Ice-crush­ing, frozen desserts: This gad­get han­dles crush­ing ice very well and any frozen ingre­di­ents, even with min­i­mal liq­uid. It quick­ly deliv­ers chunks of free smooth­ies from frozen food and shaved ice to make decent-qual­i­ty snow cones and oth­er frozen desserts using a pre-set pro­gram to process frozen food.

Juic­ing: This machine will not squeeze text­book juice that is sup­posed to sep­a­rate the liq­uid from the fiber. But it is per­fect­ly capa­ble of pro­duc­ing a rea­son­ably smooth smooth­ie, aka “whole juice.”

Puree­ing and chop­ping: Equipped with two pre-set pro­grams and a pulse mode, it purees raw or cooked food and chops veg­eta­bles and grat­ed cheese. It also makes per­fect-qual­i­ty sal­sas, dips, and sauces. How­ev­er, it is unable to make nut butter.

Hot ingre­di­ents: This machine can­not be used with hot ingre­di­ents and does not have heat­ing ele­ments, so it will not make any hot soups. The blender is not suit­able for prepar­ing bul­let­proof coffee.

Grinding/milling: This blender comes only with one set of blades that is intend­ed for liq­uid food pro­cess­ing, so it does not per­form very well when grind­ing and powdering.

This blender is a great entry-lev­el gad­get for peo­ple who want to make indi­vid­ual smooth­ies to take out with them in the sim­plest pos­si­ble way. It is a com­pact and easy-to-store machine that does not take up much room in your kitchen, and it is designed to serve one or two peo­ple at most. But it is not a ver­sa­tile machine that han­dles all of the func­tions a coun­ter­top blender does. As with all per­son­al blenders, it is also not flex­i­ble in terms of adding ingre­di­ents dur­ing blend­ing because the jar is posi­tioned in an upside-down fash­ion dur­ing food processing.

Base Unit and Motor Power

The Nin­ja (BN401) Nutri Pro Per­son­al Blender has a pow­er­ful 1100-watt at-peak motor and a 21,000 RPM blade that, as already men­tioned, blends each job very well. How­ev­er, some of the dri­ve gear parts are made of rub­ber and plas­tic rather than steel. This affects the dura­bil­i­ty of the motor construction.

The base unit is also made of plas­tic, but it looks very sol­id and pre­mi­um. It has real­ly nice suc­tion cups under­neath, so the machine does not trav­el or turn around dur­ing oper­a­tion. In addi­tion, the cord con­ve­nient­ly wraps away in stor­age under the base unit.

Speed Settings and Programs

ninja bn401 blender controlsThe Nin­ja (BN401) Nutri Pro Per­son­al Blender with Auto-iQ con­trol pan­el offers a count-up/­count-down time dis­play and 4 but­tons — START/STOP, CRUSH, SMOOTHIE, and PULSE.

The Auto-IQ fea­ture is rather a pro­mo­tion­al trick. In fact, it fea­tures two pre-set pro­grams — CRUSH and SMOOTHIES. These pre-pro­grammed timed cycles essen­tial­ly blend at dif­fer­ent speeds, paus­ing and puls­ing to make sure all ingre­di­ents are pushed down to the blade. In addi­tion, while pre-set pro­grams run, the time counter will count down the time left until the cycle end.

The SMOOTHIES pre-set lasts for 50 sec­onds and is typ­i­cal­ly used for nor­mal smoothies.

The CRUSH pro­gram lasts 60 sec­onds and is used to blend ice, frozen and hard ingredients.

If you want to stop the CRUSH or SMOOTHIES pro­gram before the end of the cycle, just press the action but­ton again or the START/STOP button.

The START/STOP but­ton and the already men­tioned func­tion to stop the pre-set cycle before the pro­grammed time can also be used for the man­u­al set­ting of the blender sin­gle-speed cycle that lasts 60 sec­onds. Dur­ing this sin­gle-speed cycle, the timer counts up the time from the start of the cycle.

The PULSE func­tion is intend­ed for man­u­al con­trol oper­a­tion, and it puls­es until you press it down and the timer count­ing-up by seconds.

Nev­er­the­less, these two Auto-iQ pre-set pro­grams are an advanced fea­ture for a sin­gle-serve blender, allow­ing more flex­i­bil­i­ty to the user than just blending.


The Nin­ja (BN401) Nutri Pro Per­son­al Blender comes with two (2) X 24 ounces BPA-free poly­car­bon­ate con­tain­ers and two sips and seal plas­tic lids ready to be tak­en out­side if need­ed. Both cups have a MAX line to ori­ent the user with the vol­ume of food need­ed to be filled. It also has black mea­sur­ing marks in ounces and ml that are easy to see.

The blend­ing cups are designed to fit eas­i­ly into stan­dard car cup holders.


ninja bn401 blender bladeir?t=kitchen0a03 20&language=en US&l=li3&o=1&a=B085L82ZDPThe Nin­ja (BN401) Nutri Pro Per­son­al Blender uses the stan­dard for all Nin­ja per­son­al blenders and attach­ments 4‑prong and 2 addi­tion­al spikes in the cen­ter Pro Extrac­tor Blades Assem­bly. The blade is made of stain­less steel and is very sharp. Nev­er­the­less, the blades tend to wear out with­in 1 year and need to be replaced, even though they are stain­less steel. The blade assem­bly gas­ket is not remov­able; it firm­ly fits around the blade base.

The blad­ed disc and the post are made of plas­tic and nylon. Unfor­tu­nate­ly, plas­tic parts also reduce the qual­i­ty and dura­bil­i­ty of the blades.

The old Nin­ja Bl480 mod­el had a prob­lem with seal­ing part of the blades that could start leak­ing with­in 1 year. This mod­el is new and has not been checked by the time, but we hope the Nin­ja improved the design and elim­i­nat­ed this problem.

Ease of Using and Cleaning

Set­ting up and oper­at­ing: Nin­ja (BN401) Nutri Pro Per­son­al Blender is very easy to set up for run­ning. Fill the cup with ingre­di­ents and liq­uid up to the MAX line. Screw in the blade assem­bly to the cup tight­ly enough to pre­vent leak­ing, but not too tight; oth­er­wise, you will have the pain of remov­ing it. Turn the cup upside down and turn it clock­wise until click to fix it to the base unit. Press the appro­pri­ate but­ton to run.

Once the Nin­ja Nutri Pro Blender is fin­ished blend­ing, you remove the blade cap, then pop on a sip­py lid, and it is ready to be tak­en away with you.

Clean­ing: The Nin­ja Nutri Pro Per­son­al Blender clean­ing rou­tine is also not dif­fi­cult. If you blend thick ingre­di­ents, soak the blade assem­bly imme­di­ate­ly after use and fol­low with a clean water rinse. Please do not allow the blade assem­bly to dry because it will be hard­er to clean. If you blend­ed watery ingre­di­ents, it would be fine to rinse them with water.

Although the blade assem­bly and con­tain­ers are top-rack dish­wash­er safe, you are rec­om­mend­ed to clean them man­u­al­ly to extend the blender’s durability.

Still, from time to time, you will need to dis­man­tle the blade assem­bly for prop­er clean­ing in order to pre­vent dirt build up between the blade and the plas­tic cap adden­dum. And it is a very chal­leng­ing task since you can only remove the blade from the plas­tic cap with a thin, dull knife or an awl.

Ninja (BN401) Nutri Pro Special Features

Col­ors: The Nin­ja (BN401) Nutri Pro Per­son­al Blender comes in one black and sil­ver color.

Cer­ti­fied Refur­bished: The Nin­ja (BN401) Nutri Pro Per­son­al Blender does not yet have cer­ti­fied refur­bished models.

Use in coun­tries out­side of USA/Canada: The Nin­ja (BN401) Nutri Pro Per­son­al Blender is sold in the USA and comes with a 110–120 volt­age sys­tem which could be used only in the USA, Cana­da, most Cen­tral and South Amer­i­can regions, Japan, Tai­wan, and Sau­di Ara­bia (coun­tries sup­port 11–12- volts sys­tem). The machine could be used through a volt­age adapter, prefer­ably for a short peri­od. How­ev­er, this machine is avail­able in many coun­tries around the world and is bet­ter to be bought via local retailers.



The Nutri Nin­ja Auto iQ with an 1100-watt motor pro­duces a lot of noise. It out­puts 100 dB (deci­bels). A hand drill pro­duces 98 noise lev­el deci­bels to under­stand bet­ter what that means, and a motor­cy­cle will out­put 100 dB. For those who can­not tol­er­ate this loud­ness for 45–60 sec­onds, I rec­om­mend that you place a rub­ber­ized table pad under­neath the blender, which should notice­ably reduce the noise output.

    Thank you for a good review — I only wish I would have seen it before I bought mine. All that you said is true. The real frus­tra­tion that I have is that the “O‑Ring” that goes inside the blade part has stretched so bad­ly that it rolls upward and will not secure the blade part to the cup. (MAJOR LEAKING). I have looked and looked online to find just anoth­er o‑ring and can­not find one any­where that will fit. I don’t need the blade part, just a sim­ple o‑ring! Unfor­tu­nate­ly, I tossed the old one so I don’t have the size even, to look for one at a hard­ware store. That’s my best bet I guess, unless some­one on this site has sug­ges­tions. Oth­er­wise, mine has been good for pro­tein shakes and chops up ice real well.
