The 10-ounce Ember Mug 2 keeps coffee or tea at a chosen temperature while a homeschool parent moves between lessons, snacks, read-alouds, and household tasks. Set the temperature from 120°F to 145°F through the Ember app, or let the mug remember the last setting. It maintains heat for up to about 80 to 90 minutes away from the coaster, depending on conditions, and stays warm throughout the day while resting on the included charging coaster.

Smart sleep conserves the battery when the mug sits empty. Hand-wash the mug rather than placing it in the dishwasher.

A small daily comfort for homeschool parents who never get to finish a hot cup of coffee.
