The electric stirring cup you mentioned, with full-automatic magnetic rotating functionality, seems to be a coffee mug designed to mix beverages automatically. These cups typically use a built-in magnetic stirrer to create a swirling motion within the cup, ensuring that your drink is thoroughly mixed without the need for manual stirring.

The magnetic rotating mechanism is powered by a rechargeable battery and is activated by a button or switch on the cup. When activated, the magnetic stirrer located at the bottom of the cup starts to rotate, creating a swirling effect that helps blend the contents of the cup.

These types of cups are commonly used for mixing hot beverages such as coffee, tea, hot chocolate, or even powdered drinks. They can be convenient for individuals who prefer their drinks to be consistently mixed or who want to dissolve powdered additives evenly without clumping.

When considering purchasing an electric stirring cup, it's essential to consider factors such as capacity, material quality, ease of cleaning, battery life, and overall customer reviews. Checking reviews and ratings from other customers can provide valuable insights into the cup's performance, durability, and user experience.
