I've been using the "vv" ego batteries for years, thinking they were the best of both worlds
until last week when I picked up a Smoktech vv twist. This thing is perfect for what I need, the problem is that with the amount I vape even the 1000mah battery doesn't last me all day. I need this same battery but with a passthrough so that when I get home from work I can just plug my tank into my passthrough at my desk and keep on working and vaping. I've checked all my usual vendors and google but I haven't found one, hoping one of you knows something that I don't.
