The intelligent self-heating mug is made from durable materials, combining PC and 316 stainless steel. It boasts the ability to maintain the temperature within the range of 50 to 62.5 degrees Celsius for up to 3 hours without requiring a charging coaster. With the coaster, the mug can sustain this temperature all day long. The package includes a charging coaster, allowing users to recharge the mug once its battery power runs low.
