Mi Vacuum Flask

The Mi Vacuum Flask is equipped with a unique vacuum insulation technology to keep beverages hot or cold for up to 12 hours. Its stainless steel construction is lightweight and offers a leak-proof design, making it an ideal companion for outdoor activities.

1. Material: Vacuum flasks are often made of stainless steel, which is durable and provides good insulation. Some may also have outer layers made of plastic or other materials for additional protection.

2. Insulation: The key feature of a vacuum flask is its double-wall construction with a vacuum between the walls. This helps to prevent heat transfer through conduction and convection, maintaining the temperature of the contents.

3. Lid and Stopper: The lid of the vacuum flask is typically a screw-on design with a sealing gasket to prevent heat exchange. The stopper or cap is also designed to minimize heat loss and often includes a pouring mechanism.

4. Capacity: Vacuum flasks come in various sizes, ranging from small, single-serving flasks to larger containers suitable for multiple servings.

5. Temperature Retention: The ability to retain temperature varies among different vacuum flasks. High-quality flasks can keep liquids hot or cold for an extended period.

6. Design and Style: Xiaomi products often have a sleek and modern design. The vacuum flask may include features like a non-slip base, ergonomic shape, and easy-to-use mechanisms.
