What resistance do you normally run?
So you are asking expert level questions of a novice vaper, but I'm going to try and answer as best I can. I bought the Origin - it's my very first mechanical... mainly I bought it because I have been wanting a Caravela since the day I started vaping, and can't get one (real tears), and it was the closest thing I could find aesthetically.
As soon as I got it, I tried my various tanks on it and soon discovered that mechanical mods don't work well with carto tanks and Protanks, etc - they need low resistance tanks like rebuildables to produce good vapor because they don't deliver as much voltage as say, a Provari (which was my first real vaping purchase). Luckily for me, although I do not own a rebuildable (yet), I happened to have a carto tank that was hand-blown - it's only like 1.8 ohms. That works great on the Origin - produces wonderful clouds.
But again, this is all brand new to me. What I like about mechanicals is that they are pretty, and I'm an aesthetics hound. As far as function goes, I love my Provari because it can handle anything I want to put on it. But let's face it - it's not that attractive to look at.
So that's where I'm at - I know my future lies in RBA's but I can't pull the trigger yet. Kinda nervous about doing the whole "build it yourself" thing without someone here to show me the ropes.
I just want to set up my Origin at it's smallest size with an 18350 and be sure I've got the highest quality battery possible in it for the price. That's because I want it tiny. I like tiny.
As for the cheap purple crappy mechanical, looks like it only takes 18500's or 18650's. And I hate it already. But still, if I'm, going to vape on it, I want something safe.
