Vape

I use titanium dual coil atomizers.  Most vape pens do not allow you to leave the power on for ever. I have one that holds 4 AA batteries and one that holds 3.  It can melt the rubber insulator near the threads on the atomizer.

I also blow glass.  These pipes are the best.  the have a flat bottom so they dont roll around.  They have an air hole pushed inward so it wont spill from the air hole.  They have a mouthpiece also designed to prevent spilling.
