Designed to be used on-the-go, the new Ember Travel Mug (Generation 2) does more than simply keep your coffee hot. Our smart heated travel mug allows you to set an exact drinking temperature and keeps it there for up to 3 hours, so your coffee is never too hot, or too cold. Easy to clean. The mug is safe to hand-wash and submersible up to 1 meter in water. The leak-proof lid is dishwasher safe. Includes a new, redesigned charging coaster. 12 fl. oz (355 ml).
