Designed to go wherever you go, the Ember Travel Mug 2 and its companion app on your iPhone or Apple Watch allow you to set your precise drinking temperature for hot beverages, track caffeine consumption, save presets for your favourite drinks, name your mug and more. Or you can adjust the temperature by tapping the touch display on the mug. Ember also maintains your chosen temperature for approximately three hours, so your warm beverage stays perfect from the first sip to the last drop anywhere you are.
