Best Xiaomi Mijia Thermos Flask Vacuum Insulated Stainless Steel 1.5L  1.8L Long Lasting Hot & Cold Thermal Kettle

The Xiaomi Mijia Thermos Flask 1.5L  1.8L is a large-capacity vacuum-insulated thermal flask designed to keep your favorite beverages hot or cold for extended periods. Built with a 316L stainless-steel inner liner and multi-layer vacuum insulation, it combines thermal performance with a practical design for home, office, meetings, travel and outdoor use.

Available in 1.5L and 1.8L capacity options, this Xiaomi Mijia thermos is suitable for individual users, families and group serving. Depending on the variant, the flask can maintain beverages at 75°C or above for approximately 6 hours and keep cold beverages at below 9°C for approximately 6 hours under specified test conditions.

Its wide opening, controlled-pour design, pressure-relief system and durable stainless-steel construction make it convenient for everyday beverage storage.

Common Problems with Ordinary Bottles and Flasks

Ordinary bottles may not provide the thermal performance, capacity or pouring convenience needed for everyday use.

Common problems include:

• Drinks becoming cold too quickly
• Cold beverages warming up quickly
• Frequent refilling
• Difficult cleaning
• Spilling during pouring
• Poor sealing
• Limited capacity
• Uncomfortable handling with hot beverages

For users who regularly prepare tea, coffee or cold drinks in larger quantities, a properly insulated thermal flask can be a more practical solution.

Smart Solution for Long-Lasting Hot & Cold Drinks

The Xiaomi Mijia Thermos Flask uses vacuum insulation to reduce heat transfer between the beverage and the surrounding environment.

This allows hot and cold beverages to maintain their temperature for considerably longer than ordinary bottles. Its large capacity also makes it useful when you need to serve multiple people without repeatedly returning to the kitchen for refills.

Key Features

1. Available in 1.5L & 1.8L Capacities

Choose the capacity that best fits your requirements.

1.5L

The 1.5L version is suitable for everyday home use, office desks, small gatherings and travel.

1.8L

The larger 1.8L version provides additional capacity for families, meetings, group outings and longer days away from home.

Current listings identify multiple Mijia thermos variants, so the exact model number should be checked against the selected capacity.

2. 316L Food-Grade Stainless Steel Inner Liner

The inner liner uses 316L stainless steel, providing a durable and corrosion-resistant surface for beverage storage. It is designed to help preserve the natural taste of drinks without easily absorbing beverage odors.

3. Advanced Vacuum Insulation

The flask uses a high-vacuum insulation structure to reduce heat exchange.

This helps maintain the temperature of:

• Tea
• Coffee
• Hot water
• Herbal drinks
• Cold water
• Iced beverages

The available specifications indicate hot retention of ≥75°C after approximately 6 hours and cold retention of ≤9°C after approximately 6 hours under specified conditions.

4. Long-Lasting Hot & Cold Temperature Retention

Whether you want hot tea during a workday or chilled water during outdoor activities, the Xiaomi Mijia Thermos Flask is designed for both hot and cold beverage storage.

Hot: ≥75°C after approximately 6 hours
Cold: ≤9°C after approximately 6 hours

Actual performance can vary depending on initial beverage temperature, ambient temperature, filling level and how frequently the flask is opened.

5. Anti-Backflow Leak-Resistant Pouring Design

The specialized outlet is designed to provide smoother pouring while helping reduce liquid backflow and accidental splashing.

This makes serving hot drinks more controlled and convenient.

6. Convenient Press-to-Open Lid

The lid uses a press/open mechanism designed for quick access.

The handle-mounted outlet control also makes pouring more convenient when serving beverages.

7. Wide Mouth Opening

The wide opening makes it easier to:

• Fill the flask
• Add ice cubes
• Pour beverages
• Clean the interior
• Remove remaining beverage residue

Some listings specify approximately a 71mm mouth opening for the 1.5L/1.8L versions.

8. Double Pressure-Relief Safety System

The flask incorporates pressure-relief features designed to help manage internal pressure when handling hot beverages.

This helps make opening and pouring more controlled when the flask contains hot liquid.

9. Durable Stainless-Steel Outer Shell

The outer shell is listed as 304 stainless steel, while the inner liner uses 316L stainless steel.

This combination provides a durable exterior while maintaining a food-contact-oriented inner surface.

10. Non-Slip Base

The bottom includes a silicone cushion designed to provide additional grip and help protect the surface underneath the flask.

Why Choose Xiaomi Mijia Thermos Flask?

A small travel bottle may be convenient, but it often requires frequent refilling.

The Xiaomi Mijia Thermos Flask provides a much larger capacity while combining vacuum insulation, stainless-steel construction and controlled pouring.

For users who regularly prepare several cups of tea, coffee or chilled beverages at once, its 1.5L / 1.8L capacity can reduce the need for repeated refilling.
