Ember Coffee Mug with Longer Lasting Battery: Our updated smart coffee mug's extended battery life keeps your drink at your preferred temperature (between 120°F - 145°F) maintaining your chosen temperature for up to 80 minutes with the Ember Mug 2, 14 oz, or all day when paired with the included charging coaster.

Smart With or Without App: Pair this temperature control mug with the Ember app to set the temperature, customize presets and more; Our self-heating coffee mug is also functional without the app and remembers your last-used temperature (135°F out of box)

Smart LED: LED light at the base of the mug will inform you when your beverage is heating up or cooling off, when it is ready to drink and when your battery needs to be charged. Personalize your mug by changing the LED to your favorite color.

Auto Sleep: Our heated coffee mug intelligently senses when to turn on and off; The mug enters sleep mode when empty or after 2 hours of inactivity; Ember wakes up when it senses movement or liquid

Hand Wash Only: An updated scratch-resistant coating is safe to hand wash; Ember Mug 2 is IPX7 rated and fully submersible up to 1 meter deep. Please do not put Ember in the dishwasher.

Do not microwave Ember! Ember is an electronic device, which should never go in a microwave.

Perfect Gift for a Life Well Sipped: Whether self-gifted or given to another, there's no better way to share warmth than a favorite drink at just the right temperature every time

Included with your Ember Coffee Mug: Charging coaster, adapter, and quick start guide.
