Designed to be used wherever life takes you, the Ember Tumbler does more than simply keep your coffee hot. Our largest mug yet, the 16 oz Tumbler 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. It features our most advanced chip ever for improved Bluetooth reliability and a simplified pairing process. All Tumblers come with two lids, letting you choose between the leakproof Handle Lid or spillproof Sliding Lid. Made with a durable stainless steel construction, Ember Tumbler is easy to clean and is safe to submerge up to 1 meter in water. Both lids are dishwasher safe.

Ideal for espresso-based drinks such as cappuccinos, cortados, and flat whites, the new Ember Cup, 6 oz, offers a premium coffee experience that does more than keep your coffee hot. Our smart mug allows you to set your preferred drinking temperature, so you can enjoy your expertly crafted hot drink —just the way you like it— from the first sip to the last drop. Ember Cup’s built-in battery maintains your precise drinking temperature for up to 1.5 hours or all day with the included charging coaster.

We never understood why to-go tumblers made design decisions that compromised the coffee drinking experience. The senses–taste, smell, and touch–were ignored, while durability and extreme heat retention were prioritized. Why not both? Introducing Carter Wide Mug, a travel tumbler finally worthy of the coffee inside. Designed to amplify the senses and engineered to fit manual brewing devices, you can now enjoy coffee at its fullest, everywhere.
