Smoothies and shakes have become a daily ritual for many of us, and having a reliable portable blender makes the whole process effortless. Recently, I had the chance to test both the Ninja Blast (BC151) and the Ninja Blast Max (BC251)—two cordless, on-the-go blenders from Ninja designed for those of us who want blending freedom without being tied to the kitchen counter.
While they might look similar at first glance, there are some clear differences in performance, features, and convenience. If you’re wondering which one is the better fit for you, let’s dive into a side-by-side breakdown based on my real experience with both models.
Key Difference Between Ninja Blast vs Blast Max Portable Blender
The main difference between Ninja Blast and Blast Max lies in power, capacity, and smart functionality.
- Ninja Blast (BC151) is lighter, has an 18oz blending vessel, and uses simple controls, making it perfect for basic smoothies, shakes, and quick blends.
- Ninja Blast Max (BC251), on the other hand, is more powerful with a larger 22oz capacity, 3 Auto IQ blending programs, a detachable “Twist & Go” design, and longer runtime, which makes it a better choice if you want versatility and consistent results even with ice and frozen fruits.

Design and Build Quality
The first thing I noticed is that both blenders are built with portability in mind, but they take different approaches.
- Ninja Blast feels more like a compact travel bottle with a built-in motor base. It’s lightweight at under 2 pounds, easy to carry with the hinged handle, and fits well in my car’s cupholder. However, since the base is permanently attached, you always carry the motor along with the vessel.
- Ninja Blast Max introduces the Twist & Go detachable vessel, which is a game-changer. Once you finish blending, you just twist the bottle off the base and go. It feels more like a traditional water bottle and is 50% lighter when carried this way. This makes a noticeable difference if you’re carrying it to the gym or work.
Verdict: For pure convenience, the Blast Max takes the lead with its detachable design, but the Blast is slightly more compact.

Ease of Use
Using both models is pretty straightforward, but the controls differ.
- On the Ninja Blast, you simply press the power and blend buttons. I liked the separate power and blend controls because it prevents accidental blending while handling it. It’s very beginner-friendly and perfect if you don’t want to fuss with settings.
- The Ninja Blast Max feels more advanced thanks to its three Auto IQ programs (Smoothie, Crush, and Blend). Instead of guessing blend time, the programs automatically adjust the blending cycle for consistent results. I particularly enjoyed the Crush mode when making frozen margaritas—something the regular Blast struggled with.
Verdict: If you like one-touch simplicity, go for the Blast. If you want precision and preset versatility, the Blast Max is worth the upgrade.

Performance and Blending Power
This is where I felt the biggest difference.
- The Ninja Blast handles bananas, soft fruits, yogurt, and protein powder without any issue. It made decent smoothies, but when I added ice cubes or tougher frozen fruits, it sometimes left small chunks behind.
- The Ninja Blast Max, however, feels closer to a full-sized blender. Thanks to its Ninja PowerBlast Technology and stronger 11.1V motor, it crushed ice, frozen strawberries, and spinach much more smoothly. The texture of the smoothies was creamier, and I didn’t find leftover chunks.
Verdict: For power and smoother blends, the Blast Max is the clear winner.

Capacity and Portability
- The Ninja Blast has an 18oz vessel, which is fine for a single serving. It feels compact and travel-friendly, especially if you just need a morning shake or post-workout drink.
- The Blast Max gives you a larger 22oz capacity, which worked great for when I wanted a slightly bigger smoothie to last me through a long work session. Of course, the extra size makes it a bit bulkier, and it weighs almost a pound more than the standard Blast.
Verdict: If portability is your top priority, the Blast wins. If you want bigger smoothies, the Blast Max is better.

Battery and Charging
Both models are USB-C rechargeable and can self-clean with water and dish soap, which is super convenient.
- Ninja Blast charges in about 2 hours, and I could get around 10-12 blends on a single charge.
- Ninja Blast Max takes closer to 3 hours for a full charge, but the battery life indicator was very helpful. Instead of guessing when I’d run out of power, I always knew how much juice was left. It also lasted longer overall, which was reassuring during trips.
Verdict: Both are good, but the Blast Max battery life indicator makes it more user-friendly.
