The 4 Best Compact, Single-Serve Blenders

NutriBullet has always been a top dog in the small blender game, but its latest personal blender is a step up in terms of portability and ease of use. For your daily basic smoothie, juice, or shake (with or without protein), the NutriBullet Flex is a life—and space—saver.

The core innovation here is the removable base, lightening up your load when you need to take your smoothie on the go. The blending vessel detaches and voila, you have a portable bottle full of cold, blended goodness, ready to be drank on the way to gym or after signing on at work. When you bring it home at the end of the day, cleaning is as easy as removing the blade and throwing it in the dishwasher.

Of the options here, this is the easiest to use (and lightest to carry around with you), but it's the least powerful. There is only one blend setting and it's likely going to run into trouble with big ice chunks or especially frozen pieces of berry. The harder you run it, the more likely you are going to need to recharge after two, maybe three, rounds of blending. And a full charge can take up to two hours. So truly, emphasis on the personal with this one. You won't be making kale drinks for the whole family with this tiny motor. At $70 though, they do come in enough colors for every member of the household.
