Yeah, the istick is a great little device for what it is: a small, inexpensive step up from egos that can hold a charge for a while! But I purchased a VTR as my step up (15watt max), and abandoned it as quickly as possible. Again, nice device, but not for rebuilding, after a certain point, for me. To power dual 28ga coils, it really takes 25+ watts, so the istick would be quite limiting after a certain point.
But 40 watts is quite nice! That's all I'm getting from my mechs, if even 40 watts, and it's enough to fog up a car with a couple good blasts. I realize clouds aren't an endgame, but it does make the vape much more satisfying, for me.
You may well find yourself wanting more than 40 watts at some point, but it would be plenty for a great many tanks (as opposed to drippers).
I don't want to sell you on the DNA40, but if i were in your position, I'd look into it. Wish I could provide options, but hopefully others continue to. I just know USA-based Evolv is being rock solid with customer service at the moment, which is good for a device you plan on using for a while.
yeah I agree there is no growth with the iStick. 40 watts is pretty nice. But for me less than 50 watts is a deal breaker. Just not enough power to build some more complex rda stuff. Wish more companies would dive into the 50 watt boxes instead of seeing if they can jump start a buick.
