    Frequently Bought Together

    Frequently Asked Questions

    How do I use the Ember Tumbler?

    Simply pour in your favorite hot beverage and let the Ember Tumbler do the rest! The LED light will indicate when your Ember is trying to reach the perfect temperature and when it’s ready for you to enjoy. You can also connect the Ember to your smartphone via Bluetooth, by downloading the Ember app. The Ember app will allow you to adjust your preferred temperature, add preset temperatures, and notify you when your beverage has hit your perfect drinking temperature.

    How does the Ember Tumbler work?

    The difference between the Ember Tumbler and a typical vacuum-insulated tumbler is that the Ember Tumbler can keep your favorite hot beverage at your exact drinking temperature down to the degree. With Ember's patented technology, multiple precision sensors are able to ensure accurate temperature and liquid levels. Without the need for double walled insulation, you can feel the warmth of your drink through the Tumbler for that extra cozy sensation.

    Is the Ember Tumbler compatible with my phone? (Android or Apple)

    Due to IOS and Android bluetooth updates, not all phones may be compatible with the Ember App.

    We're continually adding more devices and improving our compatibility. See our full list of compatible devices.

    How long does the Ember Tumbler battery last?

    The Ember Tumbler was designed to last for up to 3 hours when poured in hot at a set temperature of 57°C.

    The battery life of your hot mug depends on a number of factors including but not limited to: external temperature, liquid temperature at pour, speed of liquid consumption, and your set temperature.

    Do I have to have a smart phone for the Ember Tumbler to work?

    No! Every Ember Tumbler is preset to 57°C for you enjoy right out of the box.

    Using the Tumbler independently will limit you from customizing specific feature from the Ember mobile app such as adding a custom LED color or setting a specific preferred temperature between 50°C - 62.5°C.

    Can I put the Ember Tumbler in the microwave?

    Do not microwave the Ember Tumbler! The Ember Tumbler is an electronic device, which should never go in a microwave. 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 Ember Tumbler.
