ThermoSwirl Self-Stirring Mug

ThermoSwirl Self-Stirring Mug uses contactless magnetic induction rather than an exposed propeller rod. A quiet motor sealed beneath the solid 304 stainless-steel cup floor rotates a magnetic field that spins a small, smooth food-safe magnetic rotor capsule resting at the center of the base—creating a silky whirlpool with zero pierced rubber gaskets to wear out or leak.

During normal everyday sipping, the center magnetic spot beneath the stainless floor holds the smooth rotor capsule seated against the bottom of the mug, and sipping through the included clear press-in lid provides a physical barrier as well. Even so, never tip an open cup upside down rapidly while gulping, and always keep the small detachable rotor away from young children.

It performs best with hot or chilled liquid beverages combined with soluble drink powders or light syrups—including coffee creamer, instant espresso, collagen peptides, matcha, hot cocoa, electrolyte packets, greens blends, and warm honey. Always pour your liquid into the mug first before adding powder; it is not meant for ice cubes, whole fruit, or thick smoothie purees.

ThermoSwirl features a total interior chamber capacity of 380 ml (approximately 12.8 fl oz). That everyday desktop size comfortably holds a standard 8 to 10 oz single-serve brew or kettle pour while leaving sensible headroom near the brushed stainless rim for milk, collagen scoops, and active vortex motion without splashing onto your desk.

No. Because the mug body houses a sealed rechargeable motor assembly alongside a metal 304 stainless-steel chamber, never place ThermoSwirl inside a microwave oven or an automatic dishwasher, and avoid submerging the outer shell in standing sink water. Simply lift out the magnetic rotor pill and hand-rinse the smooth interior cup with warm soapy water.

No disposable batteries are required at all. ThermoSwirl incorporates a built-in rechargeable battery topped up easily with the included USB charging cable. Because blending a cup of coffee, cocoa, or electrolytes only takes 15 to 25 seconds per press, a single charge comfortably powers many daily beverage routines before needing a quick recharge.

ThermoSwirl is a double-wall insulated self-stirring mug, not an active electric heating element or plug-in kettle. Its double-wall matte-white shell combined with the clear press-in sip lid helps slow heat loss from hot coffee or tea while keeping the outside cool to hold, so pour your drink in at the temperature you enjoy.
