Frequently Bought Together

Frequently Asked Questions

What is Ember? How does it work?

The difference between the Ember Travel Mug, and a normal travel mug is that, anything can keep something "Hot" for hours, but only the Ember Travel Mug can keep something at your perfect drinking temperature.

The Ember Travel Mug uses seven temperature sensors, a rapid cooling system, a microprocessor-controlled heating system, and temperature presets to easily dial in your perfect temperature.

How do I use Ember?

It's easy! Simply pour in your favorite hot beverage, tap the "Ember" logo, and rotate the dial on the base of the mug to choose the temperature that tastes right for you. You can also connect Ember to your smartphone via Bluetooth, by downloading the Ember app. The Ember app will notify you when your beverage has hit the perfect drinking temperature.

Can I use Ember without pairing to a phone?

Yes! Your Ember Travel Mug can be used completely independent of the phone by rotating the dial on the bottom of the mug to select your temperature. Using the mug independently will limit you from customizing specific features from the Ember mobile app such as adding a name or assigning presets to different drinks.

How long does the battery last?

The Ember Travel Mug was designed to last an average of two hours on the go. The two hour battery life is expected when pouring in liquid hot, and a set temperature of 130°F. If you like it cooler, your battery will last longer, and if you like it hotter, battery will decrease slightly.

The battery life will also vary based on a number of external factors such as: external temperature, liquid temperature at pour, speed of liquid consumption, set temperature, whether the lid is on or off, and much more.
