Ember Mug
The first generation Ember Mug has an expected battery life of little over one hour when in use without the charging coaster at a target temperature of about 130°F (54.4°C).
*Please note, battery life for both the Ember Mug and Ember Mug² can vary dramatically depending on a few factors such as pour temperature (we recommend at least 165°F (74°C) for best results), ambient temperature, desired temperature, and if there are any additions to your beverage.
