Frequently Asked Questions

What is Ember? How does it work?

The difference between the Ember Mug and a normal ceramic mug is that, anything can keep something “Hot”, but only the Ember Mug can keep something at your perfect drinking temperature.

How do I use Ember?

Simply pour in your favorite hot beverage and let the Ember Mug 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 I have to have a smart phone for the Ember to work?

No! Every Ember Mug is preset to 54°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.

How long does the battery last?

The Ember Mug was designed to last for one hour when poured in hot at a set temperature of 54°C.

The battery life 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.
