The CCELL M4B Pro is the M4 with a button: three voltage levels (2.8 / 3.2 / 3.6 V), a ten-second preheat, a child-resistant power lock, 290 mAh and USB-C in a 91 mm stainless steel pen.
Use the button to select 2.8, 3.2 or 3.6 volts – low for flavor, high for dense vapor. Two clicks start a ten-second preheat cycle, making viscous oil in cold cartridges flow before the first draw. You can still draw without pressing the button afterwards, as draw activation remains available.
Power Lock instead of accidental activation
The M4B Pro can be locked completely. Neither the draw sensor nor the button can then activate the heater in your pocket – a sensible safeguard for a device used with oil cartridges, preventing drained cartridges and protecting children. CCELL calls the function Child-Resistant Power Lock.
When to choose the M4 and when to choose the M4B Pro
Both share the same battery, thread and stainless-steel housing. The M4 is shorter and has no controls, while the M4B Pro provides voltage control and preheating and usually costs only a few euros more. Anyone who uses different cartridges or is out and about in winter will be better served by the Pro version.
