After personally testing both, I can tell you the devil is in the details. Here’s a detailed, hands-on review that dives into their strengths, weaknesses, and which one deserves a spot in your kitchen.
Key Difference Between Ninja SS151 Vs SS150 Blender
At a glance, both the SS151 and SS150 are compact, powerful, and designed for smoothie bowls, spreads, and nutrient extractions. But here’s the standout difference:

Ninja SS151 Vs SS150 Blender: Detailed Comparative Review
Design & Build Quality
Both models share the sleek TWISTi design, which means they’re compact, modern-looking, and have the signature built-in Twist Tamper. This feature is a game-changer. Instead of stopping mid-blend to scrape down the sides, you simply twist the tamper and push ingredients toward the blades for a smoother, more consistent blend.
The SS151 feels slightly more premium, with a sturdier base that reflects its slightly higher power. Both are dishwasher safe, and the plastic jars and cups are BPA-free. Size-wise, they won’t hog your countertop, making them perfect for smaller kitchens.

Ease of Use
Both machines excel in user-friendliness. You simply load ingredients, secure the lid, and press one of the Auto-iQ buttons. The SS151 has five programs, offering more precision if you like experimenting with spreads, smoothie bowls, and frozen drinks. The SS150 is simpler, with only three presets, but this simplicity might appeal to those who don’t need bells and whistles.
I found setup and cleaning to be a breeze. All parts pop right into the dishwasher, and the drizzle cap allows for ingredient additions mid-blend – something I used often when adding protein powder or honey.
Performance and Power
Here’s where the SS151 pulls ahead. That 1600-watt motor gives it an edge when blending thicker mixtures like frozen acai bowls or nut butters. It powers through dense ingredients without any sign of struggle, thanks to SmartTORQUE technology.

The SS150’s 1500-watt motor is no slouch either. It blends smoothies, frozen fruit, and soft spreads with ease. However, during my tests, I noticed it needed slightly more liquid for ultra-thick blends, whereas the SS151 powered through with less.
Functionality & Versatility
Both models are incredibly versatile for their size. The SS151 offers:
- Smoothies
- Frozen Drinks
- Bowls
- Spreads
- Extractions
The SS150 simplifies things with fewer presets, which is fine for standard smoothies and frozen treats. If you’re a culinary experimenter, the SS151 gives you more room to play.
Noise Levels
Both blenders are loud, this is common with high-speed blenders. That said, the SS151’s sound seemed slightly deeper rather than shrill, which made it less jarring during early morning blends.
