Ninja BlendBOSS vs Ninja Blast: Which Blender Should You Buy?

If you're looking for a compact Ninja blender for smoothies, protein shakes and frozen drinks, two models you're likely to come across are the Ninja Blast and the Ninja BlendBOSS.

At first glance, they may seem quite similar. Both are compact personal blenders, both allow you to blend drinks directly in a cup you can take with you, and both are designed to tackle everything from smoothies to frozen ingredients.

But there are two very important differences: power and portability.

The Ninja Blast is a genuinely cordless portable blender that can be used almost anywhere. The Ninja BlendBOSS, on the other hand, is a much more powerful 1100W mains-powered blender with a portable travel tumbler.

There's also a significant difference in price. At Foy's Electrical, the Ninja Blast is €65, while the Ninja BlendBOSS is €149.95.

So is it worth spending the extra €84.95 on the BlendBOSS?

In this guide, we'll compare the Ninja Blast and Ninja BlendBOSS side by side to help you decide which one is right for you.

Ninja BlendBOSS vs Ninja Blast at a Glance

The easiest way to choose between them is to ask yourself one question:

Do you need the blender itself to be portable, or do you simply want the drink to be portable?

Ninja Blast – Best for Portability & Value

The Ninja Blast BC151UK is designed for people who want to be able to blend without needing access to a plug socket.

Its rechargeable battery and compact design mean you can use it at home, at work, at the gym or while travelling.

Simply charge the motor base using USB-C, add your ingredients and blend directly in the 530ml cup. The leak-resistant sip lid and carry handle then make it easy to take your drink with you.

Despite its compact size, the Blast is designed to tackle frozen fruit and ice as well as everyday smoothies, protein shakes, frozen drinks, iced coffees, dips and dressings.

At €65, it's also the considerably more affordable of the two. The Ninja Blast is available in black or Forest Green.

Why Choose the Ninja Blast?

The biggest advantage is straightforward: you don't need a plug socket.

You can make a protein shake at the gym, blend a smoothie at work or take the Blast away for the weekend.

It's also extremely simple to operate, making it a great choice if you don't need lots of programmes or settings and simply want a convenient personal blender.

Best for:

• The gym
• Work
• Travel
• Protein shakes
• Everyday smoothies
• Smaller kitchens
• Students
• Anyone looking for an affordable personal blender
• Anyone who genuinely wants to blend away from home

Ninja BlendBOSS – Best for Power & Performance

The Ninja BlendBOSS DB351UK takes a very different approach.

Although its tumbler is designed to travel, the blender itself uses a powerful 1100W mains-powered motor.

That gives the BlendBOSS considerably more blending power than a small rechargeable portable blender.

Its CrushBlade system is designed to tackle tougher ingredients and crush ice, while three Auto-iQ programmes – Smoothie, Blend and Crush – automatically control the blending pattern for you.

You blend directly inside the large 710ml tumbler. Once you're finished, remove it from the motor base, fit the leak-proof lid and straw and take your drink with you.

Why Choose the Ninja BlendBOSS?

The BlendBOSS makes sense if you like the convenience of a portable tumbler but don't actually need to operate the blender away from home.

You're getting the performance of a much more powerful personal blender combined with a cup designed to leave the house with you.

Best for:

• Frozen-fruit smoothies
• Ice-heavy drinks
• Thick smoothies
• Protein shakes
• Green smoothies
• Frequent blending
• Everyday home use
• Anyone prioritising blending performance over cordless portability

Which Is More Powerful?

The Ninja BlendBOSS wins easily.

Its 1100W motor is designed to provide substantial crushing power, with Ninja's CrushBlade system capable of tackling ice and frozen ingredients.

The Blast is impressive for a cordless blender and can handle ice and frozen fruit, but it's powered by a rechargeable 7.4V battery.

That's the trade-off for portability.

If your typical smoothie contains plenty of frozen fruit, ice or other tougher ingredients and you intend to make it in your kitchen anyway, we'd choose the BlendBOSS.

If your priority is being able to blend wherever you happen to be, the Blast has the advantage.

Winner: Ninja BlendBOSS

Which Is Better for Smoothies?

Both are excellent options for everyday smoothies.

For straightforward fruit smoothies, protein shakes and breakfast drinks, the Ninja Blast provides plenty of versatility – particularly considering its €65 price.

However, if you regularly make thicker smoothies containing lots of frozen ingredients, we'd favour the BlendBOSS because of its more powerful motor and dedicated Smoothie Auto-iQ programme.

The BlendBOSS also has the larger usable capacity, which may be useful if you prefer a more substantial morning smoothie.

Winner for everyday smoothies & value: Ninja Blast

Winner for thicker/frozen smoothies: Ninja BlendBOSS

Which Is Better for Protein Shakes?

For straightforward protein shakes, we'd actually choose the Ninja Blast.

If you're simply combining protein powder with milk, water, fruit or other relatively easy-to-blend ingredients, you don't necessarily need the additional power of the BlendBOSS.

And this is exactly where the Blast's cordless design becomes particularly useful.

You can take the blender to the gym or work and make your shake when you're ready to drink it.

At €65 compared with €149.95 for the BlendBOSS, it's also difficult to justify paying the additional €84.95 if protein shakes are your main reason for buying a blender.

Winner: Ninja Blast

Which Is Better for Ice & Frozen Fruit?

Both are designed to handle frozen ingredients, but the BlendBOSS is the stronger choice if this will be a regular part of your routine.

The 1100W motor drives Ninja's CrushBlade system to tackle ice and frozen ingredients, while the dedicated Crush Auto-iQ programme takes care of the blending pattern automatically.

The Blast uses Ninja Blast Technology and a ribbed cup design to create a vortex that draws ingredients towards its stainless-steel blades. It's impressively capable for a compact cordless machine, but the BlendBOSS provides considerably more power.

Winner: Ninja BlendBOSS

Which Is Better for Work?

This depends on when you want to blend.

If you want to make your smoothie at home and take it to work, the BlendBOSS works beautifully because its tumbler becomes your travel cup.

If you want to take the ingredients with you and make your drink at work, the cordless Blast is more convenient.

There's no need to find a plug socket – assuming the battery is charged, you can blend wherever you are.

Winner for blending at work: Ninja Blast

Which Is Better for the Gym?

The Ninja Blast.

Its cordless rechargeable design is exactly what makes it so useful for this type of situation.

You can take the blender itself with you and prepare your shake when you actually want to drink it rather than making it before leaving home.

The BlendBOSS tumbler is perfectly suitable for carrying a pre-made drink to the gym, but the blender itself needs mains power.

At €65, the Blast also makes a lot of sense for someone buying specifically for fitness and protein shakes.

Winner: Ninja Blast

Which Has the Bigger Cup?

The BlendBOSS.

The Ninja Blast comes with a 530ml blending vessel with a 470ml maximum fill capacity.

The BlendBOSS comes with a 710ml travel tumbler with a 650ml maximum fill capacity.

So if you prefer larger smoothies or shakes, the BlendBOSS gives you considerably more room.

Winner: Ninja BlendBOSS

Which Is Easier to Use?

The Blast wins for sheer simplicity.

Add your ingredients and use the straightforward controls to blend or pulse.

The BlendBOSS gives you more automation, however.

Its three Auto-iQ programmes are:

• Smoothie
• Blend
• Crush

There's also a manual Pulse function.

The Auto-iQ programmes automatically control the blending pattern, so although the machine offers more options, it can take some of the guesswork out of getting the consistency you want.

Simplest: Ninja Blast

Best automatic programmes: Ninja BlendBOSS

Which Is Easier to Clean?

Both have been designed with everyday convenience in mind.

The Ninja Blast's cup and lid are dishwasher safe, and you can also add water and a small amount of washing-up liquid and run a blending cycle for quick cleaning.

On the BlendBOSS, the removable parts are dishwasher safe.

For most users, there isn't enough difference here to make cleaning the deciding factor.

Winner: Tie

Which Is Better for a Small Kitchen?

Both are considerably smaller than a traditional full-size blender, but the Ninja Blast is the more compact option.

Because the Blast combines the blending vessel and rechargeable motor into a portable design, there's no separate mains-powered blender base taking up permanent space on your worktop.

If counter or cupboard space is limited, the Blast is an attractive option.

Winner: Ninja Blast

Is the Ninja BlendBOSS Worth the Extra €84.95?

This is perhaps the most important question in the comparison.

At Foy's Electrical, the Ninja Blast costs €65, while the Ninja BlendBOSS costs €149.95.

That's a significant difference, so we wouldn't recommend automatically choosing the BlendBOSS simply because it's the more powerful machine.

For €65, the Ninja Blast offers a lot. You get a genuinely cordless rechargeable blender that can handle smoothies, protein shakes, frozen fruit and ice – and you can use it almost anywhere.

The BlendBOSS costs €84.95 more, but you're paying for a very different level of blending performance.

Its 1100W mains-powered motor, CrushBlade system, larger tumbler and Auto-iQ programmes make it better suited to people who blend frequently and regularly use tougher or frozen ingredients.

So is it worth paying more?

For occasional smoothies, protein shakes and blending on the go: probably not. Choose the Ninja Blast.

For frequent home blending, thicker smoothies, frozen ingredients and ice-heavy drinks: the additional power of the BlendBOSS can justify the higher price.

Rather than thinking of the BlendBOSS as simply a better version of the Blast, we'd think of them as two different products at very different price points.

Which Makes the Better Gift?

The Ninja Blast is an excellent gift option.

At €65, it sits at a much more accessible gift price while still feeling like a substantial branded present.

Its cordless design also gives it broad appeal. It could make a great gift for someone who:

• Goes to the gym
• Loves smoothies
• Makes protein shakes
• Takes breakfast to work
• Travels regularly
• Is heading to college
• Has recently moved into a new home

At Foy's Electrical, the Ninja Blast is available in Black and Forest Green, giving you a choice of finish too.

The €149.95 BlendBOSS is more of a premium gift. We'd choose it for someone you know is really into smoothies, fitness, frozen drinks or home blending and will appreciate the additional power.

Best affordable gift: Ninja Blast

Best premium gift: Ninja BlendBOSS

Ninja Blast or BlendBOSS: Which Should You Buy?

Our recommendation comes down to budget, portability and power.

Choose the Ninja Blast if...

You want a genuinely portable cordless blender at an affordable price.

At €65, it's a particularly good choice for everyday smoothies, protein shakes, the gym, work and travel.

It's also our pick if you're buying a portable blender as a gift.

Choose the Ninja BlendBOSS if...

You want a much more powerful personal blender with a portable tumbler and you're prepared to pay more for that performance.

At €149.95, it's a considerably bigger investment, but the 1100W motor, CrushBlade system, larger tumbler and Auto-iQ programmes make it the better option for frequent blending, frozen ingredients and more demanding recipes.

Final Verdict

The Ninja Blast and Ninja BlendBOSS may look like two versions of the same idea, but they're actually designed for quite different customers – and their prices reflect that.

At €65, the Ninja Blast is our choice for portability and value. Its rechargeable cordless design means you can blend almost anywhere, making it particularly appealing for work, the gym, travel and everyday protein shakes and smoothies. It also makes a great gift without moving into premium-appliance territory.

At €149.95, the Ninja BlendBOSS is our choice for power and performance. It sacrifices cordless operation in favour of a considerably more powerful 1100W motor, larger tumbler and intelligent Auto-iQ programmes.

So don't simply ask which Ninja blender is better.

Ask yourself where you want to blend, what you want to blend and how much you want to spend.

If you want affordable cordless convenience, choose the Ninja Blast.

If you want considerably more power for blending at home, choose the Ninja BlendBOSS.

At Foy's Electrical, you'll find both the our Ninja Blenders in a choice of colours, making it easy to find the right Ninja personal blender for your routine and budget.
