Feature:1. 3 Temp Levels: Adjustable three gears temperature, to meet the needs of temperature use, and the heat conversion rate is about 60% higher than that of general heating materials.2. Function: The carbon fiber heating cloth radiates far infrared light waves into the human body, and the heat energy is directly transmitted to the tissues and organs of the human body.3. Long Life: The electric cloth heater is made of carbon fiber material, which makes it wear resistant and durable, and has a long service life.4. Fabric: The heating pad has a waterproof layer, a thickened thermal layer, an infrared heating layer, a thickened thermal insulation layer, and a bottom waterproof layer.5. Safe and Reliable: Carbon fiber generates heat, has minimal electromagnetic radiation, and is harmless to the human body. It is safe and secure to use.Specification:Item Type: Electric Heating PadMaterial: Carbon Fiber Heating ClothUse Voltage: DC5VTemperature:High: 35-40Medium: 30-35Low Temperature: 25-30.Package List:1 xElectric Heating PadNote:Please supply power according to the voltage used, using other voltages may cause fire and product damage!
