Shaker Cup USB Charging Shaker Cup for Protein Shaker Meal Replacement Shake Portable Gym Water Bottle Mixing Cup 450Ml

This shaker cup builds motorized mixing directly into the base of a 450ml protein shaker, so instead of relying on a mixing ball and vigorous shaking, you press a button and let the built-in mechanism blend powder and liquid together. That makes it a convenient option for protein shakes and meal replacement drinks, where clumping can be more of an issue than with a simple pre-workout mix.

It's available in two finishes — Black at $43.99 and Ivory at $44.99 — and is designed to be charged or powered so the motor is ready whenever you need it, rather than requiring a fresh battery each time. The 450ml capacity is sized for a single serving, and the parts are designed to come apart for cleaning after use.

Because the mixing mechanism sits in the base, this cup is meant for cold or room-temperature drinks rather than hot liquids. It's a straightforward upgrade for anyone who mixes shakes often and is tired of dealing with a mixing ball rattling around or powder that doesn't fully dissolve with regular shaking.
