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.

3 Hour Battery Life: Our Tumbler’s extended battery life keeps your drink at your preferred temperature (between 120°F – 145°F) for up to 3 hours on a full charge or all day on its charging coaster.
Beyond Insulation: Feel the warmth of your drink through the Ember Tumbler’s durable stainless steel construction and premium textured finish. Tumbler features all the benefits of insulation with none of the drawbacks.
Adventure Ready: Tumbler comes with two lids and is IPX7 rated for full underwater submersion up to 1 meter deep making it easy to hand wash, rinse or soak.
Perfect Temperature Every Time: Multiple sensors throughout the Tumbler ensure accurate temperature control and liquid level detection. Set the temperature down to the degree in the Ember App.
Our Biggest Mug Yet: At 16 oz this is the largest heated temperature control mug we have released to date.
