What it does well
Ember makes temperature control drinkware for home and travel. The Mug 3 comes in desk friendly and smaller sizes plus an espresso cup, while the Tumbler 2 uses a slimmer shape that fits car cupholders. Heaters and sensors inside each vessel maintain the temperature selected on the mug or tumbler or through the optional app. Indicator lights display temperature and battery status during use and charging. Each heated piece pairs with a charging coaster for longer desk sessions and includes a sliding lid that extends warmth. The mugs and tumblers are top rack dishwasher safe after drying before charging.
Our full take
Maker of temperature controlled drinkware, including the self heating Ember Mug 3 and Tumbler 2.
