Smart mugs are innovative drinking vessels designed to maintain the temperature of beverages like coffee or tea. They often come with built-in heating elements and can be controlled via a smartphone app, allowing users to set their preferred temperature. Some models even feature notifications to remind users when their drink is at the desired warmth. In addition to temperature control, many smart mugs are equipped with features such as spill-proof lids and rechargeable batteries. Brands like Ember and Cauldryn have popularized these products, making it easier for people to enjoy their drinks at the perfect temperature throughout the day.
