Hello all, I've been vaping for a year coming up this month and have sworn by mods with internal batteries and I'm noticing that through out the day that as the charge lessens I have to turn up the watts or have to take a way deeper drag to get the effect I get when it's newly charged. So what I've heard is that a regulated box mid that takes removable and rechargeable batteries give you the same freshly charged hit until it needs recharging, is this true? And if it is what would be a good affordable choice, I don't really sub ohm yet so I'm looking for something around 30-50 watts that can run a clearo or dropped, affodable in case I do. Sorrry for the long post
