Characteristic Parameters

  • Power on/off:
    Press the button 5 times to power on/off. The screen will enter standby mode after 10 seconds of inactivity.

  • Connecting:

    • When the atomizer is connected in standby mode, the green light flashes 1 second to wake the screen.

    • In no-load mode, the white light flashes 3 times.

    • In short circuit mode, the red light flashes 3 times.

    • Screen display: Current power and gear are shown when powered on. If idle for 10 seconds, the screen turns off and enters standby.

  • Preheat:
    Press 2 times within 1.5 seconds to start automatic mode and preheating.

    • 1.8V preheat lasts 15 seconds.

    • Screen shows “preheating” and flame mark flashing.

    • After preheating, normal display resumes.

  • Smoking (use):
    Press the button to smoke, gear lights up.

    • Screen display: Current power level, gear, puff count.

    • Turns off if idle for 10 seconds.

  • Stepless voltage:
    Adjustable range: 1.8–4.2V.

    • Flip the switch upward: increases by 0.1V per step.

    • Flip downward: decreases by 0.1V per step.

    • Holds to adjust continuously.

    • Cycles back to 1.8V after max.

    • Ambient light flashes when adjusting.

  • Battery indicator:

    • Short press (when off): wakes the screen but not the light.

    • Long press: lights up display.

    • 5 bars = battery level (each bar = 20%).

    • Screen display: Short press shows current power/gear briefly, then turns off.

  • Puff count function: Yes.

  • Clear puff:
    Press the button twice, then hold down the third time to clear puffs.

Charging Specifications

  • Low battery voltage:
    Below 3.2V → red light flashes 10 times + 2 vibrations.

    • Screen display: Power shows 0.

  • USB charging current:
    5V/0.5A with overvoltage protection.

    • Power off to charge.

    • Does not support fast charging.

  • Charging:

    • Red = charging

    • Green = fully charged

    • Screen display: 5 bars cycle until full, charging mark stays lit when full.

  • Charging time: ~60 minutes

  • Charging high-voltage protection:
    5V/0.5A = normal.
    7V–28V → protection triggers, stops charging current.

Protection Features

  • Smoking timeout:

    10s puff → red light flashes 4 times, device stops.

  • Switch memory:
    Screen display does not change.

  • Overload:
    PCBA with overvoltage protection.

  • Short-circuit protection:
    Red light flashes 3 times, output cut off.

  • No load:
    White light flashes 3 times.

  • Overload (low resistance):
    If resistance < 0.8 Ω → white light flashes 3 times, standby.
