Designed to go wherever you go, the Ember Travel Mug and its companion smartphone app allow you to set your precise drinking temperature for hot beverages, track caffeine consumption, save presets for your favorite drinks, name your mug and more. The temperature can also be adjusted with a touch display on the mug. Ember 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.
