So what your asking is for help with picking a good cig-alike e-cig for travel?
Since, I'm guessing you have 510 cartos, the volt is an 808. thats what we normally recommend.
So the volt is kind of out of the question unless you wanna buy new cartomizers for it.
The volt is interesting because as far as I know, it is actually regulated at 3.x volts.
So you do get a consistent vape throughout the battery. I forget what it is regulated at though.
the eRoll is a tiny, very light, cig alike, that is actually regulated at 3.7 volts. Awesome right!?
The only problems are the battery is only 90 mah, so when it goes in your pocket, it NEEDS to go in its PCC.
the PCC is 1300 mah I believe, so with 2 eRoll batteries, your good in most situations outside the house.
And the eRoll uses proprietary atomizers with the 510 tanks, that do not hold a lot of
juice.
So you may need to carry around a small bottle of
juice in your pocket if your a heavy vaper.
Both are great cig alikes though. Just make sure you do bring an eGo for when you really want a no hassle vape.
