I just got a 510 to cartomizer adapter for my riva today. I tried it out with a couple dif flavors and it just wasn't hitting right. The I put the cartos on my little PSAce and I am getting monster hits. Why am I getting more vapor and more flavor from a battery that small? Is the adapter creating more resistance? Does the riva batt put out smaller voltage. This is blowing my mind because now I'm just angry that my riva which last me 12 hours isn't performing up to par with my little PSAce that I have to switch out for a good hit every 2 hours
