Luckily I'm a vape guy as well as an electrical engineer, so i know what your referencing - but this is definetitly not how it's done. Typically VW devices will be requlated to some voltage using a switching network; buck, boost or something even fancier. Often times, as in the case of the vamo and provari, they are boosted up then PWMd down to the desired power level. This circuit is essentially a liner regulator - which dissipates all excess energy as heat
