The Ember Mug 2 is a 10 oz heated mug that holds coffee or tea at a set temperature between 120°F and 145°F, controlled from a phone app. Its built-in battery keeps the drink warm for up to 1.5 hours off the charging coaster, or indefinitely while the mug sits on the coaster. It suits desk workers and slow sippers who dislike reheating or finishing a drink cold. Against plain insulated mugs, which only slow heat loss, it actively heats; against cheaper heated-mug copies, the app presets and temperature accuracy are its edge, though owners report the battery fades over time and the mug is not dishwasher safe.
