Not Your Average Mug
The Ember Smart Mug 2 (14 oz) takes the humble coffee mug to a whole new level, packed with innovative and thoughtful features. Let’s explore these in detail:
Precise Temperature Control
Gone are the days of guessing the temperature of your coffee or tea. With the Ember Smart Mug 2, you can set your drink’s temperature anywhere between 120°F and 145°F (50°C to 62.5°C). This range allows for flexibility depending on your drink of choice—whether you prefer piping hot coffee or gently warmed herbal tea.
Using the Ember app, setting the temperature is as easy as sliding your finger on the screen. The app provides precision and remembers your preferences, ensuring every cup is exactly how you like it.
Even if you don’t use the app, the mug operates intelligently, defaulting to 135°F—a sweet spot for most beverages. Plus, the mug remembers your last setting, so it’s always ready to deliver your perfect sip.
Built-In Battery Power
This battery-powered mug isn’t just smart—it’s portable. The 14 oz version boasts up to 80 minutes of battery life.

When placed on its charging coaster, the Ember Mug provides all-day warmth, making it ideal for desk use or extended relaxation. The coaster is compact and minimalist, blending seamlessly into any space.
Smart LED Indicator
The LED indicator is a surprisingly delightful feature. This small light at the bottom of the mug serves multiple purposes:
- It lights up to notify you when your beverage has reached the perfect temperature.
- It flashes when the mug is low on battery or when charging is needed.
- You can personalize the LED color through the app for a touch of personality.
This feature ensures you’re always in the loop, making your coffee or tea experience even smoother.
Auto Sleep & Motion Detection
The Ember Smart Mug 2 isn’t just smart—it’s intuitive. Thanks to its built-in motion sensors, the mug knows when to turn on or off.
- It wakes up automatically when you pour hot liquid into it.
- It enters sleep mode when empty or idle for a prolonged period.
This feature not only saves battery life but also eliminates the hassle of manually turning the mug on or off. It’s a “set it and forget it” level of convenience.
Hand Wash Safe & Submersible
Cleaning the Ember Smart Mug 2 is straightforward. While it isn’t dishwasher-safe, it’s designed to be fully submersible up to 1 meter, making hand washing simple and efficient. Its scratch-resistant coating ensures the mug stays looking brand-new even after frequent use.
This durability makes the Ember Mug 2 a practical choice for daily use, whether you’re enjoying coffee at your desk or tea on the couch.
Ember App Integration
The Ember app is the hub of your smart mug experience, offering a range of features for customization and control.

The Ember‘s 120°F to 145°F range is thoughtfully designed to cater to various preferences on the set temperature:
- 120°F: Ideal for delicate beverages like herbal teas or hot water with lemon.
- 135°F: The default temperature, perfect for most coffees and teas, offering warmth without being too hot to enjoy.
- 145°F: Great for those who love piping hot drinks or need their beverages to stay hot longer in cooler environments.
This versatility of the heating element ensures the mug suits a wide variety of users, from casual tea drinkers to coffee connoisseurs.
Compatibility Across Drinks
While it’s easy to focus on coffee, the Ember Smart Mug 2 excels with any hot beverage:
- Coffee: Keeps your morning brew steaming until the last sip.
- Tea: Offers precision control for delicate green teas, robust black teas, or herbal infusions.

The Ember Smart Mug 2 (14 oz) redefines what a mug can be. Its robust features cater to convenience, personalization, and performance, making it a standout product for anyone seeking the perfect sip every time.

The 80-minute battery life is generous, especially for portable use. When placed on its coaster, which doubles as a charging pad, the mug keeps drinks hot all day without interruptions. The mug’s ceramic coating feels durable and resists scratches, maintaining its polished look after repeated use.
Overall, the build quality and performance are exceptional. Ember clearly prioritized durability and functionality.
Coffee Meets Convenience
Using the Ember Smart Mug 2 is as simple or as high-tech as you want. The default temperature is set to 135°F, perfect for most hot beverages. You can customize this using the app, which is intuitive and packed with useful features.
The app allows you to:

- Receive notifications when your beverage reaches the desired temperature.
- Personalize the LED light color for a touch of fun.
Not a fan of apps? No problem! The mug remembers your last temperature setting, making it a great standalone device. And unlike basic mug warmers, which only heat standard ceramic mugs, the Ember temperature control mug keeps warming on-the-go. It’s a great option for slow sippers that prefer flexibility and ease of use in a modern design.
Is It Worth the Price?
At a premium price point, the Ember Smart Mug 2 is an investment in your daily routine. If you value consistently hot beverages and love gadgets, it’s worth every penny.

Nextmug vs. Ember Smart Mug 2
When compared to the Ember Smart Mug 2, the Nextmug focuses on straightforward usability. While Ember offers app connectivity and precise temperature control, it can feel overly complex for some users. In contrast, the Nextmug eliminates the need for apps, prioritizing simplicity with its intuitive button controls.
The Ember Smart Mug 2 also allows finer temperature customization (120°F to 145°F), whereas the Nextmug’s preset options may appeal more to users who prefer quick adjustments. Both mugs offer sleek designs, durable builds, and charging coasters for all-day warmth. However, the Nextmug’s spill-resistant lid is a bonus feature not included with the Ember mug, making it more travel-friendly.

The Nextmug is perfect for users who want a reliable, stylish, and easy-to-use self-heating mug. It’s especially appealing to those who prefer simplicity over extensive tech features.
