Rather than just right out welcome you, I'm going to help you.
Hell, I'll do both.
WELCOME!
Now hunker down with me for a bit, get your pen and copybook ready!
E-cigs run on electricity, and as with any device, the way it runs and the efficiency sort of matters. Your current setup isn't likely to be too efficient at burning your juice with enough amperage, and as such, is more than likely giving you weak drags, minimal vapor and poor flavor.
What you can do to eliviate this issue, is to pick yourself up some low resistance gear and by gear I mean cartomizers or atomizers, of any resistance below 2.5-3ohms.
They are available on most websites. Consider Madvapes, Crystal-Clear-Vaping and Electronicstix. Consider Boge Cartomizers as well as Smoktek 1.5-1.8ohm single coil cartomizers. They should provide your ego, even with its limited voltage, a very satisfying vaping experience.
You can also consider getting 18mg e-juice to see if it gives your head more of a spin and satisfies your cravings.
