This electric shaker bottle is designed for anyone who wants a quick and consistent way to mix protein shakes or other powdered drinks. The container is made from Tritan, a material that offers good clarity and impact resistance, and it contains no BPA. Instead of manual shaking, the bottle uses a vortex mixing system that creates a lively swirling motion inside, which helps break up clumps and blend ingredients smoothly. This action also provides an engaging visual effect. The bottle is powered by a rechargeable battery that holds enough energy for many mixing sessions. A full charge takes approximately two hours, and under typical use of a few times per week, the battery can last about a month before needing another charge. The motor runs with enough power to handle most protein powders, though users may notice slightly less mixing efficiency when the battery level becomes low. Cleaning the bottle is straightforward. After finishing a drink, pour in some warm water with a drop of dish soap, then activate the mixer. The vortex action will rinse the interior, making it easy to clean without taking apart any parts. Color: Blue. Material: Plastic.
