This stainless steel shaker bottle combines vacuum insulation with a rechargeable electric mixer to help prepare protein shakes and meal replacements with ease. The double-wall insulation keeps drinks cold for extended periods, making it a practical choice for workouts, travel, or daily hydration needs. Instead of shaking manually or using a separate blender, a simple press of a button activates the built‑in mixer, which blends protein powders, supplements, or meal replacement mixes with water or milk. In about 30 seconds, the drink becomes smooth and free of clumps. The bottle works well with thicker additions like peanut butter, though it is not meant for crushing ice or juicing fruits. The electric mixer is powered by a rechargeable battery that charges through a USB‑C port. A full charge takes roughly two hours, and the battery can support daily use for up to a month when used twice per day. This makes the bottle convenient for regular users who do not want to recharge often. Cleaning is straightforward. The bottle body and lid are dishwasher‑safe, which saves time and effort. The silicone rings inside the lid can be removed for thorough cleaning, while the base that contains the electric parts is best wiped by hand to maintain its function. Color: Black.
