I have never heard of smobot but quickly said "Want dat!" Added to the buy soon list.
If you have the newer “Reggulator” it will not fit. It will fit the older “Daisy Wheel” cap. Or they make an aftermarket cap for it.
I had the daisy wheel cap as I had purchased a floor model. But bought their cap anyhow. You also might want a small usb charge pack to run it. A cheaper one that had power to the usb all the time. It draws very little power and mine will easily last 12-14 hour smokes only consuming less than 1/4 the battery.
