Can I put the Tumbler in the microwave?

Do not microwave the Tumbler. As with all electronics and metals, it may result in a fire when heated up in the microwave. Doing so will result in permanent damage to your Tumbler.

Can it be used to warm up drinks from room temperature?

The Tumbler was designed to bring a hot beverage to a resting set temperature and maintain that set temperature for a period of time. Pouring in a colder beverage may result in the mug not heating or reading as empty.

What is the Charging Coaster Voltage?

The charging coaster can accept anything between 100VAC and 240VAC and is safe to use with an international converter that supports the appropriate amount of voltage.

What is the temperature range?

With the Ember App, we allow the precision temperature control between 120°F (50°C) and 145°F (62.5°C), covering a wide range of preferred hot beverage drinking temperatures.
