The M3B Plus was built bigger than the rest of the M3 family to fit all sizes of cartridges. It is compatible with 0.5ml, 1ml, 2ml, or even larger volumes, ensuring access is always at your fingertips regardless of your cartridge size. 

Select between the battery’s three voltage settings (2.8/3.2/3.6V) to your liking for flavor, vapor, or for a happy medium by tapping the button 3 times in quick succession. The LED lights will tell you instantly which voltage you’ve chosen, ensuring a seamless and simple experience every time. 

By tapping the button 2 times in quick succession, the preheat functionality programmed into the battery will be activated for 10 seconds, immediately freeing up any potential cartridge clogs. 

The button was designed with extra safety in mind. You can turn the device on or off with 5 button taps and activate the battery when it is on with a single press and hold. Both button operations ensure a high level of safety, preventing unintended activation in pockets or use by minors.
