NutriBullet Portable vs. Power: Showdown... Tested & Black Magic personal blender use case We’ve tested the NutriBullet Portable (NBPB50100K) in our quest for the perfect on-the-go blender, and the results are compelling. The sleek black 20oz vessel feels robust yet lightweight, thanks to its cordless USB-C rechargeable design. We loved whipping up smoothies in minutes without sacrificing flavor, as the motor handles fruits and nuts with ease. The USB-C charging adds convenience, eliminating the need for bulky adapters. While the power isn’t as hefty as its counterpart, it more than meets personal blending needs. For our Black Magic use case—quick, nutrient-packed smoothies post-workout—this device excelled. It’s not overkill, but it delivers a satisfyingly smooth result every time. A solid choice for those who value portability without compromises.
