Brand New Ember Mug 2 offers up to 90 minutes of heat (120°F to 145°F) or all-day warmth on its charging coaster. Ideal for keeping drinks at the perfect temperature, perfect for desk use or as a thoughtful gift. Smart or Standalone: Use the Ember app to set precise temperatures and get notifications. Without the app, the mug defaults to 135°F and remembers the last setting for a consistent experience.
