Frequently Asked Questions


The difference between the Ember Mug² and a normal mug is that, anything can keep something “Hot”, but only the Ember Mug² can keep your favorite hot beverage at your perfect drinking temperature. Whether you call it an electric mug or battery heated coffee mug, your Ember Mug² allows you to control your ideal temperature from our app

Simply pour in your favorite hot beverage and let the Ember Mug² do the rest! The LED light will indicate when your Ember is trying to reach the perfect temperature and when it’s ready for you to enjoy. You can also connect the Ember to your smartphone via Bluetooth, by downloading the Ember app. The Ember app will allow you to adjust your preferred temperature, add preset temperatures, and notify you when your beverage has hit your perfect drinking temperature.

Do not microwave the Ember Mug! The Ember Mug is an electronic device, which should never go in a microwave. As with all electronics and metals, it may result in a fire when heated up in the microwave. Doing so will result in permanent damage to your Ember Mug or Ember Mug².

No! Every Ember Mug² is preset to 57°C for you enjoy right out of the box.

Using the mug independently will limit you from customizing specific feature from the Ember mobile app such as adding a custom LED color or setting a specific preferred temperature between 50°C - 62.5°C.

The Ember Mug², 10 oz was designed to last for up to 1.5 hours and up to 80 min for the Ember Mug², 14 oz when poured in hot at a set temperature of 57°C.

The battery life of your hot mug depends on a number of factors including but not limited to: external temperature, liquid temperature at pour, speed of liquid consumption, and your set temperature.

In addition to Ember.com, The World’s First Temperature Control Mug is available in retailers across the globe such as Apple, Best Buy, Target, Starbucks, Harrod’s, and Bloomingdale’s. Whether you like coffee, tea, or a hot-tail we want you to enjoy your beverage at the perfect temperature and just the way you like it.
