My white TW mega cartomiser/cartomizer shows orange flashing/pulsating light inside it when I vape. It doesn't have to be used very long, the last one started after a very few puffs.
It's this model:
I started out using it on my Screwdriver MkI with a long adapter - not a pretty sight
... and didn't notice anything amiss (except it's a nuisance to fill and juice tends to run right thru
),
I think I only get the internal "flames" since I've been using it on my Garry Dibley Passthru with a 2A hub which gives 5v vaping.
Could it be that the mega carto must not be used at more than 3.7v?
