Ember Coffee Mug LONG LASTING BATTERY: Our upgraded smart coffee mug has extended battery life and keeps your drink between ideal temperatures (48.9 °C - 62.8 °C) (100 °F - 140 °F) for up to 80 minutes
App smart or not: pair the temperature controlled mug with the Ember app, set the temperature, customize presets, and more; our self-heating coffee mug also has a feature that remembers the last temperature used without the app (57.2°C out of the box).
AUTO-SLEEP: Our heated coffee mug intelligently senses when it's turned on and off; the mug goes into sleep mode when empty or after 2 hours of inactivity; Ember wakes up when it senses motion or liquid.
Hand Wash Only: Upgraded scratch-resistant coating is hand wash safe; Ember Mug 2 is IPX7 rated, fully submerged up to 1 meter
PERFECT LIFE GIFT: Whether for your own use or as a gift to others, there is no better way than your favorite drink to share warmth at the right temperature
