How does the Ember Tumbler work?

The difference between the Ember Tumbler and a normal mug is that, anything can keep something “Hot”, but only the Ember Tumbler 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 Tumbler allows you to control your ideal temperature from our app.

How do I use the Ember Tumbler?

Simply pour in your favorite hot beverage and let the Ember Tumbler 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.

Can I put the Ember Tumbler in the microwave?

Do not microwave the Ember Tumbler! The Ember Tumbler 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 Tumbler.

Do I have to have a smart phone for the Ember Tumbler to work?

No! Every Ember Tumbler is preset to 135°F for you to 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 120°F - 145°F.

How long does the Ember Tumbler battery last?

The Ember Tumbler was designed to last an average of three hours on the go. The three-hour battery life is expected when pouring in liquid hot, and a set temperature of 135°F. If you like it cooler, your battery will last longer, and if you like it hotter, battery will decrease slightly.The battery life will also vary based on a number of external factors such as: external temperature, liquid temperature at pour, speed of liquid consumption, set temperature, whether the lid is on or off, and much more.

In addition to Ember.com, our products are 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.
