Ninja BlendBoss review: Fun meets functional with this powerful personal blender

I know what you're thinking — Ninja saw the viral Stanley Cup tumblers and said "hold my smoothie." But there's a lot more than an on-trend aesthetic to like about the Ninja BlendBoss: it's stupidly powerful for a single-serve blender, blasting through ice, frozen fruit, and even dips with ease. In fact, the eye-catching design might be the least impressive thing about this single-serve blender.

First released in the U.S. in 2025, and now available to buy in the U.K., the BlendBoss is part of a new drive from Ninja to make kitchen gadgets that you not only need, but also want to have in your home. And if you ask me, the BlendBoss is an excellent example of how fun can meet functional.

I put the BlendBoss through its paces in the Tom's Guide test kitchen to see how it compares to the best blenders, and there's what happened.

Ninja BlendBoss: Specs

Ninja BlendBoss: First impressions

I was sent the BlendBoss in Lavender Lemonade, which combines a purple base with a purple and yellow pitcher. The pitcher is tinted, meaning all my drinks looked a little purple until I poured them out.

Each blender comes with one tumbler, so you'll need to buy extras if you want the whole family to take their blended drinks on the go. Except, there's a catch — they're currently all sold out at the SharkNinja website, and they retail for $39, which isn't cheap. With the likes of NutriBullet blenders, you'll usually get a minimum of two cups and a number of lids for sipping or simply covering in the fridge, so the BlendBoss is less versatile in this regard.

What it lacks in add-ons, the BlendBoss makes up for in features. It has three settings: Smoothie, Ice Crush and Blend, and an AutoIQ setting which will automatically tailor your blend cycle to the ingredients you add to your cup.

Its 1100-watt motor is well above what I'd expect for such a compact blender. It does make the base very weighty, but given its low profile it's still easily portable and will sit just about anywhere in your kitchen.

As for its Stanley Cup-esque design, the likeness doesn't end with the shape and handle. It also comes with a pop-up lid and a straw that can be inserted so it pops up when you open the cup. If, like me, you're so committed to drinking out of a silly little straw that the idea of using a normal cup does not appeal, this is a feature you'll enjoy using.

Ninja BlendBoss: Performance

If you were wondering if the BlendBoss is style over substance, I'll jump to the chase and say that it aced every single test I gave it. I was not only impressed, but also incredibly surprised. This is easily the most powerful single-serve blender I've tested —and I've tested a lot!

Smoothies

First up, I made a smoothie from frozen berries, oats, milk and honey. This is a classic in my house, and a good test of any blender's ice crush mode. Frozen cherries are a challenge for any blender, and if left un-blended oats and berry seeds can make the texture of the smoothie quite gritty.

I added the ingredients to my cup, screwed on the blending lid and switched to Ice Crush mode.

The BlendBoss is noisier than I was expecting. On my SoundMeter app it hit 92dB when crushing my frozen ingredients, which is as loud as the Vitamix Ascent X2 which currently sits in the top spot of my blender buying guide.

However, like the Vitamix, the end result is worth a bit of grief from your neighbors. My smoothie was thick and ice-cold, with no lumps or un-incorporated ingredients. The only thing that stopped it from hitting Vitamix-level creamy (and for reference, the Vitamix is six times the price) was some seeds and a little bit of oat grittiness, which is absolutely to be expected with a smaller blender.

Protein shakes

My partner makes a protein shake for breakfast every morning, so in my house, it's the number one reason for having a blender. Sure, you could use a shaker, but a blender will leave your drink well-mixed and lump-free.

I added a scoop of chocolate protein, some ice and some milk to my cup and turned the blender to Smoothie mode. The blender took just shy of a minute to finish blending, and the result was incredibly creamy.

This is the sort of drink I could feasibly throw straight in my bag and take into the office or to the gym, so I added my straw and popped on the to-go lid. The lid opens when you press a discrete button on the front of the lid, and there is a risk of something pressing against this button in your bag and flipping the lid clean open.

We ran some slightly unscientific tests in the kitchen to see if this could feasibly happen. Fortunately we found that unless you directly press against the button, there's no spill risk.

Brushing against it won't cause it to pop open as the button isn't overly sensitive, and when I shook the bottle upside-down nothing spilled from the sides or top. Still, I think it'd be good if Ninja added a lock feature to this lid, which is a feature you'll find on bottles from Owala and the like, to make sure there's no chance of accidental spills.

Hummus

I doubt Ninja made this blender with the expectation of people using it to make hummus, but it's one of the standard tests we do when testing blenders, and I wanted to give the BlendBoss a proper challenge.

To my cup I added a tin of drained chickpeas, tahini, olive oil, garlic, seasoning and a couple of ice cubes (which I'm told give a smooth and creamy result) and twisted the cup into place.

This seemed like the perfect test for the IQ setting, which detects the strength and timings needed and adjusts accordingly.

When I've made hummus in personal blenders before, I've needed to take my cup off and give the contents a stir to make sure they're all blended evenly, so it was a real surprise when the BlendBoss automatically pulsed to evenly mix in my drier mix and the hummus started to swirl around inside the blending cup, no assistance needed.

Texturally, the finished result was easily as good as the hummus I've eaten at my favorite Lebanese restaurant. With some fine-tuning, I could happily never buy a tub in the supermarket again! It was incredibly creamy with no lumps or grittiness, the dip scooped easily out of the cup and into my serving bowl.

Ninja BlendBoss: Cleaning

Blenders are some of the most annoying appliances to clean, but fortunately the BlendBoss cup, lid and straw can all go in the dishwasher. Hooray! If you're cleaning by hand, this is also easy enough. I used a scrubbing brush to get the caked-on patches of protein powder away from the base of the cup, and due to the relative lack of grooves compared to something like the Beast blender, there weren't any fiddly areas I struggled to clean.

Should you buy the Ninja BlendBoss?

I'd buy this blender, and I'd recommend you do too. It's hard to fault its performance, and I also think it's very competitively priced for such a powerful option. While I'd never score it bonus points just for looking cute, let's be honest, it's easy on the eyes and that's never a bad thing!

The only real reasons not to buy the BlendBoss are if you want to use more than one blending cup, given the (at time of writing) lack of extras available at the SharkNinja website, and if the 24oz capacity would be too small for you. But if you're in the market for a super cute and capable personal blender, this is the one I'd recommend.
