1. Standby state (sleep state): In standby mode, briefly press the button once, and the nixie tube will display the current percentage of electricity. At the same time, the boost circuit will work and the output will be turned on. If there is no load for 40 seconds Turn off the left and right digital tubes and turn off the output, and the entire machine enters standby mode; 2. Charging status (display current battery percentage) A. When the TYPE-C port is connected to an external power source, the digital tube displays the current battery level and flashes to indicate charging. After fully charging, the digital tube displays 100%. 3. Power on status (display current battery percentage, start boost output): A. After pressing the button, the nixie tube displays the current percentage of battery power. If there is no load or the load is less than the maintenance current of 50mA (+/-30mA), at a certain time After the boost is turned off, the digital tube goes out and enters a sleep state. If the load is greater than 50mA (+/-30mA) or above, please refer to "Discharge Status" for details. 4. Discharge state, load greater than 50 mA (+/-30mA): A. Single port output supports fast charging. B. Simultaneous output from multiple ports, does not support fast charging
