Anyone else experiencing this or have any ideas?
I also have an early one.
I know you said it is not the cartridge, but...
Any time I have an issue with no vapor coming, it is always the cartridge connection.
Sometimes just lifting it out and putting it back is enough, but usually, I give the contacts a quick cleaning. The connection can get fouled with minute amounts of oil.
I clean with a quick iso-on-a-swab or an alcohol wipe. Remove the mag adapter so you can wipe those threads, and wipe the contact point down inside the Vault's cartride well. This has always worked for me.
Unrelated:
I just got some live rosin carts (my first, very excited) but they are too fat to fit in the Vault SE (or any Vivant).
I think these are a little over 11mm.
Any suggestions for a battery that will take fatter carts, still having a fire button and multiple temp options? Without breaking the bank...
These carts recommend very low temp/power (for best flavor), like 2.2 watts. I am not finding one that will go that low, don't want to re-program an old box mod. The ones that I see that take wider carts are in the $50 range, seems like a lot...
