I stopped smoking like a little over a week ago using e-cigs, and now i cant go without them. I'd like to continue using e-cigs for now, whilst lowering the nicotine (im at 12mg, and going to 6 mg very soon), until i no longer crave nictone. I just ordered an Aspire Nautilus tank. This tank works for the cheap E-cigs. They come with a 510 threading i believe. I will be more sure when it gets here. I want ONE vaporizer that can let me use my Nautilus tank AND use my homemade QWISO shatter (not the best quality/pureness so id like something that can handle that). Most of the time for oil. I go for the small puffs, hold it in for 5 secs, but every once in a while I like to get some big ass hits. So i just bought a 3.7V Ti Kiss Cart to use with the G-Pen (i hope it works). I need help deciding what to buy. I want one device to power the Nautilus tank, Kiss Cart, and those extract cartidges that i can fill and use for small hits. I NEED it to be portable, and either it has a good battery that can last a lot, or I can carry another battery. 1) Which one of the Omicron lite, Persie, O-PHOS, Omicron 2.5 should I get? 2) Which cartidges should I get? 3) Would these cartidges work with other Variable Voltage E-cigs? Like the Innokins and such? Im looking at Omicron v2.5+ 2.4 ohms right now. Note: Im an amateur when it comes to oil, and I do not have access to anything better than what I make.
