Self-heating mugs are innovative drinkware designed to keep beverages warm without the need for a microwave or stove. These mugs typically use built-in heating elements powered by batteries or USB connections, allowing users to enjoy hot drinks like coffee or tea at their preferred temperature for extended periods. Many self-heating mugs come with temperature control features, enabling users to adjust the heat settings according to their preferences. Some models even include smart technology that can be controlled via a smartphone app, making it easy to maintain the ideal warmth for drinks while on the go or at home.
