This auxiliary heating belt is a flexible heating device that converts electrical energy into thermal energy. Its design power is 150W, and at the same time it has its own PTC feature, the temperature becomes higher and the power becomes lower automatically, even if it is continuously heated, it will only be slightly higher than the ambient temperature, it will not overheat, and it is safer to use. The built-in protector will automatically power off when the temperature exceeds 75.
