The Ember Mug2 is a 10 oz stainless steel mug with a built-in battery that holds your drink at a set temperature instead of letting it cool. A smart LED on the mug shows when it is heating and when your target is reached, and the companion app sets the temperature and tracks the charge. It suits desk workers, slow coffee drinkers and tea drinkers who want the last sip as warm as the first. Against a plain insulated mug it adds active heating and app control, but it costs far more, needs charging, and the 10 oz capacity is small for heavy coffee drinkers.
