How does the Ember Cup work?

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

How do I use the Ember Cup?

Simply pour in your favorite hot beverage and let the Ember Cup 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 Cup in the microwave?

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

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

No! Every Ember Cup 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.
