The 14-ounce Ember Mug 2 holds a larger serving while maintaining a steady drinking temperature through a full homeschool morning. Parents can choose a setting between 120°F and 145°F in the Ember app, save presets for different drinks, and receive a notification when the drink reaches temperature. The mug heats for roughly 80 to 90 minutes away from its coaster under typical conditions, then continues all day when placed on the included charging base.

The soft Sandstone finish suits a calm, natural homeschool workspace. Smart sleep reduces unnecessary battery use, and the water-resistant mug needs hand washing rather than dishwasher cleaning.

The larger-size Ember Mug for homeschool parents who need more than a few sips.
