I truthfully have no clue, I don't own the device, I think it would depend on lots of things including what type of juice you put in there. But, every coil is different, depending on design. I suppose theoretically one could suppose a slightly sub0hm device might last a little longer, but it depends on so many other factors (chain-vaping, juice type, satisfaction with the coil, length of puffs) I wouldn't really want to hazard a guess.
There is a very easy way to find out, I'd think?
