We designed the Simple2 Squared to be the easiest to use vape pen on the market.  

Instructions for Simple2 Squared batteries

 

Power on or off: Click the button 2 times quickly (2 times within 3 seconds).
Preheat your cartridge: The pen automatically goes into preheat mode for 10 seconds every time you turn the device on.
Change power level: The Simple2 Squared is optimized for use with all oil cartridges and has only 1 power setting.
Charging: Plug the included micro usb cord into the slot at the end of the pen.  Charge the battery with a wall charger (not in your car or with a computer).  When it is charging, the power light will be red.  When it is fully charged, the red light will turn off.

 

To use: Screw your favorite oil cartridge onto the threaded end of the pen.  Click the power button 2 times.  You can activate the pen by inhaling on your cartridge (breath activation) or pressing the button and inhaling on your cartridge.

 

Troubleshooting: The green power light will turn red when you have 20% or less power left in the pen.  2 blinking white lights indicates that you have a short in your cartridge. Most cartridges will work with the breath activation feature.  If your cartridge has low airflow or adjustable airflow it will not work with breath activation.  If this is the case, simply press the button and inhale.
