How to use?
5-Click on-off Protection: Generally, the battery is shipped in the off position. In off position,
it will be without function even when pressing the button.
To turn on battery, press manually button 5 times within 2 seconds.
You will see white LED flash.
To turn off battery, press manual button 5 times within 2 second as well, the white LED will flash!
 "5-clickon-off protection" can protect the battery from being activated when you do not want or do not use it.
Cut off Time: If the button is pressed for 10 seconds, the battery will be shutoff until the button is released.
Short Circuit Protection: When a short is detected, the battery will shutdown until the short is removed.
Low Voltage Protection: When the battery voltage is lower than 3.3v, the battery will shut down.
Over-Discharge Protection: The device will monitor the battery voltage and automatically turn off when the battery is discharged,
preventing damage to the battery by overly charging it. The LED will blink 5 times indicating that a charge is need.
 
How to adjust output voltage?
There are 16 grids on the knob at the bottom,
and each represents 0.1v. Spin the knob in a clockwise direction to increase output voltage and spin the knob in anti-clockwise direction to decrease output voltage.
High output voltage gives more vapor. You can adjust the output voltage so easily and enjoy the whole vapor time.
 
Using the battery at a higher voltage output will drain the battery faster than at a lower voltage.
We suggest you to start with a low voltage and increase the voltage gradually until you find the right voltage for your atomizer/cartomizer.
