My mod is stuck in the "v" setting. I did not do this and it will not let me vape. I have the Aspire Archon mod.

You broke it. Put some white plumber's tape around the thread of the tank before twisting it.

You cannot use that adapter to charge ecigs!
The batteries will hit up & explode because high voltage.
First of all it provides 6V which is too much and all ecigarettes that i know use a MicroUSB port for charging (or firmware update on mods)
Usually any ecig battery or mod will use the default USB voltage which is 5V and max 2.4 Amps.
Do NOT use over 5 volts on ecigs unless you got a special model that asks specifically for that power (very unlikely)
As a side effect from vaping ecigs...all i can recommend is to use more or only VG (Vegetable Glycerine) instead of too much PG (Propilen Glycol) on the liquids.
PG can give some side effects to sensible persons as dry throat, strong coughing, some throat bitterness.
Unfortunately most eliquids use plenty PG because it boosts the flavor!
