Yup, what they all said. Not too much more I can add. And no "punching."
I find the regular 78mm Volt
batteries will usually last me 2 to 3 hours of standard use before recharging (ritual, pick it up/put it down, come back after a bit, rinse/repeat). If one vapes the marathon, not putting it down, maybe an hour. The life expectancy is reported at approximately 300 charges. With as many of the
batteries as I have, I don't think I'll reach the individual 300 charges per battery any time soon. Oh, and a minimum of 3
batteries on hand, as CatLady and Cindy indicated. Me, I have at least one of each color, in each size.
I like just about all the prefilled carts from SI, and I top them off with their liquids as I go for about the aforementioned 8 to 10 fills before needing a new cart.
The X2 is nice, has more power, will last longer between charges and will use either the carts or the clearomizers. It will burn through carts a little faster than normal, but I actually prefer the carts over the clearomizers. I have used both.
