Detailed Description: The thermal energy of the carbon fiber does not pass through the medium, but the far-infrared light waves are irradiated into the human body , and the thermal energy is directly transmitted to the tissues and organs of the human body. The greatest feature of carbon fiber heater is that the amount of electromagnetic radiation is extremely small, which is harmful to the human body. p Harmless. The heat transfer rate is about 60% higher than traditional heating materials. Long service life: Due to the properties of carbon fiber, it is corrosion-resistant and durable Product Size: 24 x 30 cm Cable length: 1.8 meters 5V2A power supply Three-level temperature setting can be timed be, super soft short plush fabric, durable and not easy to deform, heating cloth can be washed, sewn, folded, rubbed, fast E warming, long life will be
