Graphene hand warmer is relatively safe. Graphene hand warming treasure is to heat through graphene. The heating speed will be faster. Basically, the temperature can be raised in about 5-10 seconds. Moreover, the temperature is relatively mild, which is close to the temperature of the human body and will not burn people too much; In addition, graphene hand warmer also has three different gear temperature control buttons, which can be selected according to the surrounding environment and personal temperature. ABS flame-retardant material is added to the inner shell, and all aluminum alloy material is used for the outer shell. It has the ability to protect against excessive temperature, overpressure and overcurrent, and its safety is relatively high.
