Our portable dynamic molecular heaters include relay groups and high voltage groups. It creates a pleasant stream of warmth that melts ice and snow on the surface. Its use method is very simple: 1. Place the instrument in a safe and stable position, 2. Open the switch to adjust the temperature, 3. The heat released by Musical Instruments keeps people warm and melts snow and ice. And the double ring structure causes the molecular U to rotate, thereby releasing kinetic energy.
