Key Features of Ember Temperature Control Smart Mug 2

The Ember Temperature Control Smart Mug 2 is a sophisticated and innovative product designed to enhance the experience of enjoying hot beverages. Here are its key features and unique aspects:

  1. Temperature Control: The Ember Mug 2 allows you to set an exact drinking temperature for your coffee or tea, ensuring it’s never too hot or too cold. You can select your preferred temperature range between 120°F – 145°F (50°C – 62.5°C) through the Ember app​​​​.
  2. Battery Life and Capacity: The mug comes in two sizes, 10 oz and 14 oz. The 10 oz version maintains your chosen temperature for up to 1.5 hours, while the 14 oz version can do so for up to 80 minutes. When placed on the charging coaster, it can maintain the temperature all day. The battery life is influenced by various factors, including external temperature, liquid temperature at pour, speed of liquid consumption, and the set temperature​​​​.
  3. Smart Features: The mug intelligently senses when to turn on and off. It features a smart LED that indicates when the beverage has reached the perfect temperature. Additionally, the mug can function without the app, remembering the last-used temperature (135°F out of the box)​​​​.
  4. App Connectivity: By pairing the mug with the Ember app via Bluetooth, you can set the temperature, customize presets, receive notifications when the desired temperature is reached, and personalize your mug. However, using the mug independently limits certain customizations available through the app, like setting a specific preferred temperature or adding a custom LED color​​​​​​.
  5. Design and Build: The Ember Mug 2 is designed for use in both home and office settings. It’s made of ceramic and has a comfortable handle. The dimensions of the 10 oz version are 4.2 inches x 4.3 inches. It comes with its own charging coaster, a cable, and a power adapter for plugging into an outlet. The mug is available in black or white​​​​.
  6. Safety and Care: The mug is safe to hand wash and is submersible up to 1 meter in water. However, it should not be placed in a microwave, as it’s an electronic device and can cause a fire hazard or damage the mug permanently​​​​.
  7. Additional Features: The mug also includes a brew timer for tea, adding convenience for tea drinkers​​.

In summary, the Ember Temperature Control Smart Mug 2 stands out for its ability to maintain a consistent temperature for hot beverages, smart connectivity features, and thoughtful design. However, it’s important to consider its limited battery life, the need for hand washing, and its price, which might be higher than traditional mugs.
