Frequently asked questions

How do I use the Ember Mug 2?
Simply pour in your favorite hot beverage and let the Ember Mug 2 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.

Can I put the Ember Mug 2 in the microwave?
Do NOT microwave the Ember Mug 2! The Ember Mug 2 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 Mug 2.

Do I have to have a smart phone for the Ember Mug 2 to work?
No! Every Ember Mug 2 is preset to 135°F for you to enjoy right out of the box. Using the mug 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 120°F - 145°F.

Is Ember Mug 2 dishwasher-safe?
No. The Ember Mug 2 is NOT dishwasher safe. It is specifically designed to be hand-washed. The mug has a scratch-resistant coating and is IPX7 rated, meaning it can be submerged up to 1 meter for 30 minutes or less. 

What Does “Open Box” Mean?

They usually have assorted stickers on the packaging and have been exposed to customer contact.
