Ember finally caters to espresso drinkers with its new heated cup. The smaller, 6-ounce mug is sized perfectly for cappuccinos, Cortados, and flat whites, keeping them warm to your ideal dinking temperature. The range can be selected from 120°F to 145°F in the Ember app, and a smart LED light notifies you when it's reached your desired temperature. Its built-in battery keeps espresso-based drinks hot for up to 90 minutes or all day when using the charging coasters, while an Auto Sleep function knows when to turn the cup on and off. Available in black and copper.
