Frequently Asked Questions


What is Ember? How does it work?

The difference between the Ember Mug and a normal 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 130°F for you to enjoy right out of the box. Your Ember Travel Mug can be used completely independent of the phone by rotating the dial on the bottom of the mug to select your temperature.

Using the mug independently will limit you from customizing specific features from the Ember mobile app such as adding a name on thee Travel Mug or LED color on the Ember Mug, or assigning presets to different drinks.

How long does the battery last?

The Ember Mug, 10 oz and 14oz were designed to last for 1 hour and 2 hours for the Ember Travel Mug, when poured in hot at a set temperature of 135°F.

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.
