Xiaomi Mijia Portable Electric Cup 2 Vacuum Flask 350ML  – Smart Heating Travel Mug

The Xiaomi Mijia Portable Electric Cup 2 350ML MJDRB02PL is a compact 2-in-1 electric heating cup and insulated travel mug designed for people who want hot water wherever they go. With a 300W heating system, 350ml capacity, 316L stainless-steel inner liner and intelligent temperature control, it combines the convenience of a portable kettle with the functionality of a thermal cup.

Unlike an ordinary travel mug, this model can heat water directly when connected to power, display the current temperature through its LED screen and maintain selected temperatures for extended periods. Its compact size makes it suitable for offices, dormitories, hotels, travel and personal everyday use.

The MJDRB02PL offers 6 temperature settings across approximately 45°C–99°C, while its 300W heating system can bring 350ml of water to boiling temperature in roughly 8 minutes under specified conditions.

Common Problems with Ordinary Travel Mugs

A conventional travel mug can keep a drink warm, but it cannot normally heat water by itself.

Common problems include:

• No built-in heating
• Having to find a separate kettle
• Drinks becoming cold during travel
• No precise temperature control
• No real-time temperature display
• Bulky electric kettles
• Limited portability
• Difficulty preparing hot water in hotels or offices

For people who frequently need hot water away from a traditional kitchen, a portable electric heating cup can provide a much more convenient solution.

Smart Solution for Hot Water Anywhere

The Xiaomi Mijia Portable Electric Cup 2 combines an electric heating system with insulated cup functionality in one compact body.

Simply connect the cup to a suitable power source, add water and select the desired temperature. The integrated heating system can heat the water, while the digital display lets you monitor the temperature. Once heated, the cup can also maintain a selected temperature when powered according to its supported operating modes.

This makes it especially useful when a full-size electric kettle is inconvenient or unnecessary.

Key Features

1. Compact 350ML Capacity

The 350ml capacity is designed for personal use rather than large-batch boiling. It is suitable for:

• Drinking water
• Tea
• Coffee
• Warm beverages
• Hot water for personal use

Its compact capacity also helps keep the overall product portable.

2. 300W Rapid Heating

The cup uses a 300W heating element designed to heat water efficiently in a compact form.

Under specified conditions, 350ml of water can reach boiling temperature in approximately 8 minutes, although actual heating time can vary depending on starting water temperature and power conditions.

3. 6-Level Temperature Control

One of the main advantages of the MJDRB02PL is its multi-level temperature control.

The product supports temperature settings across approximately 45°C to 99°C, giving users greater flexibility than a basic boil-only travel kettle.

This can be useful for:

• Warm water
• Tea
• Coffee
• Hot beverages
• Different drinking preferences

4. Real-Time LED Temperature Display

The integrated LED display allows you to monitor the current water temperature.

Instead of guessing whether the water is warm, hot or close to boiling, you can check the displayed temperature while the cup is operating.

5. 316L Stainless-Steel Inner Liner

The inner liner is made from 316L stainless steel, providing a durable material for direct contact with water.

This is particularly useful for a portable heating appliance that is regularly exposed to hot water.

6. Double-Layer Vacuum Insulation

The product uses a double-layer vacuum-insulated structure designed to reduce heat transfer and help retain temperature after heating.

This allows the cup to function not only as a heating appliance but also as an insulated beverage container.

7. Up to 12-Hour Constant Temperature

When connected to power, the product supports intelligent constant-temperature operation for up to 12 hours, depending on the selected temperature and operating mode.

This is useful when you want warm water available throughout a workday or during extended periods in one location.

8. Heat Retention After Unplugging

The cup can also retain heat after power is disconnected.

Product documentation lists approximately 6 hours of heat preservation, with one specification citing around 42°C after 6 hours under specified conditions. Actual retention varies according to initial temperature and environmental conditions.

9. Boil Water with the Lid Closed

The MJDRB02PL is designed to support heating with the lid closed, with pressure-management features intended to make this operation safer.

This helps reduce splashing and makes the product more convenient for portable use.

10. Dual Pressure-Relief Safety System

The heating cup uses a dual pressure-relief design, including a breathable membrane and pressure-relief valve, to help manage internal pressure during heating.

This is an important feature when heating water inside a sealed portable container.

11. Automatic Safety Protection

The product documentation lists multiple safety mechanisms, including:

• Overheat protection
• Dry-boil protection
• Fuse protection
• Pressure relief
• Sealing protection
• Automatic temperature management

These features are designed to improve safety during everyday heating.

12. Portable & Compact Design

The cup measures approximately 77 × 77 × 211.5mm, making it significantly more compact than a conventional electric kettle.

Its approximately 350ml capacity is particularly suited to personal use, travel and compact workspaces.

13. Universal Voltage Support

Product documentation and listings report support for 110V/220V input, making the model suitable for multiple electrical markets. However, the supplied plug can still vary by regional version, so buyers should confirm the plug configuration before use.

Why Choose Xiaomi Mijia Portable Electric Cup 2?

Its 350ml capacity, 300W heating system, LED temperature display and 316L stainless-steel liner make it particularly suitable for individual use.
