It is made of food-grade materials, holds 380 ml, and is powered by a 2000 mAh battery. For best results, fully charge the battery before first use, securely close the cup and base, chop fruit into small pieces, add water or milk as needed, and turn the blender on upside down while gently shaking it for a smooth, perfect blend every time.
