Can't get a name for this connector.
It looks like a miniature version of an ancient signal socket, last seen on signal generators from the 50s.
In this case it seems to carry simple DC reg supply from USB
For those who aren't familiar with the larger ancient implementation ( pre-PL259 ):
Well, that is an olde timey microphone/audio connector. I dont have any model number for you right at hand.
BUT, is that a USB-A connector I see at the other end in coax_noid_01.JPG?

Sure appears to be! Although from apperances the mic connector seems to be a miniature version.
The old timey microphone connector is on the output of an FM signal generator (100MHz).
The new miniature instance's use seems to be a simple USB to DC regulator.

That looks very much like the 510 connector on many of the cartridge-based and smaller tank based e-cigarettes. Your device looks like and from the description very much sounds like a charger for such batteries. See e.g.
Spot on.
