The principle of heat generation is not the same.
The pi heating sheet adopts the surface heating method, and the allowable surface power density is extremely large, and the maximum can reach 7.8W/cm2. Therefore, this product series has the characteristics of better heating uniformity and faster heating rate.
Graphene heating film is JB original, they are made graphene heating application products, the graphene far infrared produced is faceted heating, higher density penetrates the skin, relieve pain.
