Ahh, good info. Are the other brand's tanks/mouthpieces/etc. that are compatible with the halo triton? Also, how effective would simply using my 400 mah battery with some cartomizers/the cone halo provides be for a bit of a portable kit?
The thing you need to know about the Triton is that it is 808/eGo thread. This means that you can use eGo tanks on it so long as they don't have 510 threading.
Basically that means that they have a wide threaded base to screw into the wider threads on the Triton, all while pressing the center pin on the tank into the top center of the battery. I can't actually say if this is true or not since I simply do not own a Triton. The more common phrasing is "510 with eGo threading". Thus it has a 510 post on the tank, but uses eGo threading to attach to the battery. I'd imagine that those will work on a 808 with eGo threading like the Triton, but I can't say for sure since I've never had a Triton.
But if you wanted to be perfectly safe, I would simply stick with the Triton tanks, or 808 threaded cartomizers/clearomizers, preferably ones that will fit with the eGo cone attached.
