The power of the NutriBullet Portable Blender (14.80 W) is primarily designed for light to medium blending tasks, such as blending smoothies, protein shakes and fresh fruit.

- Nuts: While the blender's blades are sturdy, blending nuts can be a bit challenging as nuts are harder to blend than fruits or vegetables. However, it is possible to blend nuts if they are in close contact with the blades.
- Frozen fruit: Frozen fruit can be processed, but it is advisable not to leave it too hard as this could strain the performance of the blender. Frozen fruit can normally be blended without additional ice.
- Ice: Blending ice is not ideal with this blender as the power and blades are not specifically designed for crushing ice. The motor may be overloaded or the consistency of the smoothie may not be ideal.

Overall, the NutriBullet Portable Blender is better suited for softer ingredients, but with care and proper preparation of the ingredients, nuts and frozen fruit can also be processed. However, ice should be avoided.
