## Questions & Answers

**Q: Can I put the Tumbler in the microwave?**
A: 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.

**Q: Can it be used to warm up drinks from room temperature?**
A: 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.

**Q: What is the Charging Coaster Voltage?**
A: 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.

**Q: What is the temperature range?**
A: 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.
