Designed for home or office, the Ember Mug 2 does more than simply keep your coffee hot. Our smart mug allows you to set an exact drinking temperature, so your coffee is never too hot, or too cold. Ember then maintains your chosen temperature for up to 80 minutes with the 14-ounce Ember Mug 2 - so your hot beverage stays perfect. Easy to clean, the mug is safe to hand wash and submersible up to 1 meter in water. Includes new, redesigned charging coaster.
