Name: Mini-go/min-ego (or something of that sort)
Purpose/item: Small ego-style battery, 3.x volt battery w/ ego and 510 connections. Could possibly be used for stealth vaping, but would be better served when someone needs a pocket-sized e-cig to fit in their coat or suit pocket when they are out for a dressy night out. Something small and compact. Would also fit clutch purses well, and would still give true 3.x vaping experience w/ the ego-style experience we've come to know and love.
(Not to argue the point, but this is all one guess under name (both are the same thing in general, just two diff spellings), and purpose (i.e. "small for concealment or compactness, and it's a battery for ego-style and 510"))
