The Ninja Blast Max BC251 is a battery-powered personal blender intended for blending single-serve drinks like smoothies. It's the brand's second portable blender, and compared to the original Ninja Blast, it has a bigger 22oz jar and features a couple of blending programs, 'Crush' and 'Smoothie,' along with a manual blending option. Its blades are fixed inside the jar instead of on the motor base, which means you can carry the jar around without the motor base attached, and it also makes the blades easier to clean. The lid has a spout with a flip-up cover and a handle for better portability.
Our Verdict
The Ninja Blast Max isn't good for multi-purpose use, but it's not really designed for that. It works best for single-serve smoothies, as it makes a smooth blend with fibrous ingredients like fruit and leafy greens. It can also make snow-like crushed ice in small batches. However, it's not meant for blending dry ingredients without liquid in the jar, can't hot blend, and is generally slow at processing ingredients.

The Ninja Blast Max is great for single-serve smoothies. It does an excellent job of processing small batches of fibrous ingredients, so it makes very well-blended smoothies with fruit or kale. It can make snow-like crushed ice and has a resealable drinking lid for its jar. However, it's slow at processing smoothies, and its battery can be depleted after blending just one, depending on the amount of liquid and how fibrous your ingredients are.

The Ninja Blast Max is mediocre for multiple servings of smoothies. It's a portable personal blender mainly intended for blending for one, and its jar has a maximum capacity of 18oz. If your smoothie includes fibrous ingredients like fruit or leafy greens, it makes a smoother blend if you work with smaller batches instead of filling it to full capacity. Its battery is also likely to die after blending just one smoothie, depending on the consistency of your recipe. It's an excellent ice crusher, which is rare for portable blenders.

18oz blending capacity.
The Ninja Blast Max is adequate for crushing ice. Its jar has an 18oz blending capacity, so like most personal blenders, you have to work with small batches of around four ice cubes at once. However, using its 'Crush' program, it quickly makes uniform, snow-like crushed ice, so unlike most battery-powered benders, it's suitable for blending crushed ice for cocktails.

The Ninja Blast Max isn't suitable for soups. Like most personal blenders, you can't use it for hot blending, and its 18oz capacity means it won't fit most soup recipes in one batch. You can use it to make a mostly smooth blend with fibrous ingredients like kale or broccoli. However, using it for difficult ingredients depletes its battery quite quickly, so it's only really suitable for blending single-serve portions.

The Ninja Blast Max isn't good for professional use. It's a portable personal blender and isn't intended for heavy-duty use. It's good for blending single-serve smoothies and small batches of ice, but you can deplete its battery after blending just one smoothie, depending on your ingredients. It has a maximum blending capacity of 18oz and can't hot blend or process dry ingredients like nuts without liquid in the jar.

The Ninja Blast Max BC251 is significantly better than the nutribullet Flex overall, but the Flex does have some advantages. Get the Ninja if you often make single-serve smoothies or crush ice for drinks; it excels in these categories and will produce much smoother drinks and finer ice. Consider the nutribullet if ease of use is your primary concern. It's much quieter and features removable blades that make it easier to clean, which is a rare addition for personal blenders.
The nutribullet Flip is a better portable blender than the Ninja Blast Max BC251. The nutribullet blends fibrous ingredients faster and makes a smoother blend at full capacity, which is important for well-blended smoothies. It's a little quieter and includes a straw lid, which you might prefer. However, the Ninja is much easier to clean and is much better at crushing small batches of ice.
The Ninja Blast Max BC251 is a little better than the Ninja Blast. The Max can make better-blended smoothies with kale or fruit, as long as you don't fill it to full capacity. It's also much better at crushing ice. Its design, with blades fixed in the jar, makes it easier to clean and carry around. That said, you might prefer the Blast's more compact design.
