Ninja SS151 vs SS150 Blender: Which One Should You Buy?

Blenders aren’t just kitchen gadgets anymore; they’re an everyday essential for smoothies, sauces, frozen drinks, and even meal prep. Recently, I had the chance to put the Ninja SS151 TWISTi Blender DUO and the Ninja SS150 through their paces.

At first glance, these two machines look almost identical—same design, same 1600-watt motor, and the same smartTORQUE technology. But after spending time with both, I noticed subtle differences that may affect your decision, depending on how you plan to use your blender.

Quick Verdict: Ninja SS151 vs SS150 Blender

The Ninja SS151 and SS150 deliver essentially the same blending performance. Both use Ninja’s 1600-watt smartTORQUE motor, both include the built-in Twist Tamper, and both excel at thick smoothies, frozen drinks, spreads, and nutrient extractions without stalling. In terms of raw power and results, there is no meaningful difference.

The Ninja SS151 TWISTi Blender DUO is the more complete package. It usually includes extra to-go cups (24 oz + 18 oz), making it more convenient for households that prepare multiple smoothies or like flexibility for portion sizes. It’s marketed more widely, comes with broader accessory bundles, and is better suited for users who want everything included out of the box. That convenience typically comes at a slightly higher price, around $139.

The Ninja SS150, on the other hand, is essentially the same blender in a leaner bundle. Performance is identical, but it often includes fewer cups and accessories. Because of that, it’s usually priced a bit lower and commonly found through select retailers. If you already have compatible cups or don’t need the extras, it offers excellent value without sacrificing power.

Bottom line:

• Ninja SS151 = Same performance, more accessories, higher price
• Ninja SS150 = Same performance, fewer extras, better value

Key Difference at a Glance: Ninja SS151 vs SS150 Blender

The SS151 and SS150 share most of their core features, but the main difference usually lies in bundled accessories and retail availability. The SS151 is widely marketed as the “DUO” with more cup options and tends to be slightly more versatile, while the SS150 is often seen as a streamlined version, sometimes available at specific retailers like Costco.

If you’re looking for more included cups and recipe inspiration, the SS151 edges out. But if you want the same powerful motor and blending performance at a potentially lower price, the SS150 is a worthy contender.

My Experience with the Design

Both blenders are virtually twins in design. Compact, sleek in platinum gray, and surprisingly lightweight for the power they pack. I really appreciated the built-in twist tamper—this feature alone eliminates the usual “stop and scrape down the sides” problem I’ve faced with older blenders.

Where the SS151 stood out for me was in the accessories. Having both a 24 oz. and 18 oz. cup meant I could prep a large smoothie in the morning and still have a smaller cup for sauces or dressings later in the day. The SS150, on the other hand, felt a little limited with fewer cup options.

Ease of Use

Honestly, both models are incredibly straightforward. The Auto-iQ programs really do take the guesswork out of blending. For smoothies, I just pressed the button, and it alternated between pulsing, blending, and pausing to get everything smooth.

Cleanup was equally hassle-free. All removable parts went straight into the dishwasher, and the base wiped down in seconds. For someone like me who hates long cleanups, that’s a huge win.

Performance and Functions

This is where both models shine. With 1600 watts and smartTORQUE, I never once experienced stalling or struggling, even with frozen fruit or nuts. I made almond butter in the SS151, and it came out silky smooth in under two minutes. The SS150 performed just as well with frozen strawberries and ice, turning them into a creamy smoothie without any chunks.

The five functions—smoothies, extractions, frozen drinks, spreads, and bowls—are the same across both models. If you’re big into smoothie bowls like me, the tamper plus hybrid-edge blades combo makes a noticeable difference. The texture came out thick and spoonable every time.

Ninja Twisti SS150 High-Speed Blender Duo

• Performs identically in blending power
• Perfect for those who only need one cup size
• Compact and easy to store

Cons:

• Fewer accessories included

Conclusion: Which One Should You Buy?

After testing both, I can say there’s no real performance gap between the Ninja SS151 and SS150. Both crush ice, blend smoothies, and make spreads with the same efficiency.

If you’re someone who values extra accessories and flexibility, the Ninja SS151 DUO is the smarter pick. I found myself reaching for the smaller cup often, and having both sizes made life easier.

But if you’re on a tighter budget and don’t mind fewer accessories, the Ninja SS150 delivers the same blending power without compromise.

My Recommendation:
Go for the SS151 if you want the complete experience and multiple cups. Pick the SS150 if you just want power, simplicity, and a slightly lower price. Either way, you’re getting one of the best compact high-performance blenders on the market today.
