How to use

This device needs to be used with a power bank with an output of 5V 2.1A and 5V 2A. If the voltage and current are too high, the circuit will burn out, and if the voltage and current are too low, the heating device cannot be started.
To start the machine, you need to press and hold the power button on your chest for 3 seconds. The button slowly turns red before the heating device can be started normally. After the heating is completed, the red light turns white and enters the 55℃ medium temperature heating maintenance state.
The moment this device is inserted into the power bank, the red, white and blue lights of the button will flash once in sequence. If the button light does not turn red after pressing the button for 3 seconds, or the red, white and blue lights of the button flash once in sequence, it means that the power bank used is a power bank with non-standard voltage and current output. Please replace the power bank with non-standard voltage and current output before using.
