• No, you’ll want to have a hot liquid added to this mug and the battery will keep it warm/hot. It will not heat up cold liquids.

• Hi Lauren, thank you for reaching out! The Ember is not intended to heat up colder beverages but is actually meant to stabilize an already hot drink down to your set temperature. For best results, we recommend pouring in hotter that your set temp (around 165°F and above)!
