Above is a "true hybrid" mech mod. The
dedicated atty has 20x1 threads which attaches directly to the body of the mod; there is no top cap with a 510 connector.
Above is an example of a "faux hybrid" or direct battery mech mod. There is no center pin in the 510 connector. The atomizer attachment used MUST have an
extended center pin to make contact with the battery. Without the extended center pin the battery will make contact with the atomizer's 510 and create a short circuit.
Some mechs come with a choice of top caps: either with a normal 510 center pin or without (faux hybrid).
