Nobody likes their coffee or tea lukewarm. Ember Travel Mug 2 can solve the problem by actively maintaining the drink temperature thanks to its heating element. The tumbler can keep the beverage warm as long as possible when attached to its charging coaster. Or you may use it independently, and the battery has enough power to operate for up to 3 hours. Quickly control the temperature level from your phone or use the capacity buttons on the mug. Spill-proof design to safely keep the hot beverage from spilling while on the go.
