If you are keeping your beverage hot while using the coaster, it can maintain your perfect temperature all day! * When Ember is on the charging coaster the battery will stay at a constant level and will not charge any higher until your Ember is empty or is powered off. Please note, you may see the battery percentage drop slightly in between sips.

* The Ember has a 2-hour inactivity auto shutoff feature. Picking the Ember up to move the accelerometer will reset the 2-hour timer.
