Hello everyone, so I've reached a point I'm sure most of you can relate to, I've been trying to quit smoking and really been trying to give vaping a whole hearted effort. I started with the ego pens, then went to mechanical with an rba, and finally found my way into the regulated mod category. I like the ease of use and features that go with this style mod which led me to purchase a Innokin Cool Fire 4, with a Kanger Sub Tank . While its a great little devise, my only gripe is the limited battery life. I'm a pretty heavy vapor and only get 5 or 6 hours of sub ohm vaping out of her before i have to plug it in, I partially think the internal battery is starting to go from being used so much, so lucky me I get to buy another mod but which to chose? I'm not a stickler about brand but I would like something higher than 40w and with enough battery life to quench my vaping thirst, I plan to start looking into a nice dripper RBA in the not so distant future also. I had my eye on the Sigelei 75W TC or the iPV4S 120W but Innokin also has the Cool Fire 4 Plus. So what do you guys think? I'm looking for input on these devises or suggestions for something else.
