The Fresh Juice Portable Blender isn’t bad for single-serve smoothies. It can’t smoothly blend any recipe since it struggles to fully process fibrous ingredients like fruit skin and leafy greens. However, its battery-powered design makes it portable, so you can bring it with you and blend a post-workout shake or smoothie. It’s light and quiet when running, which is nice for a portable blender, and it’s decently easy to clean by hand.
