man the boost circuitry on these things sucks....its more like a mech!!

How so? It doesn't seem to be outputting the expected/shown voltage?
I think it s a feature of the chiNA40 chips that the boost circuit is less than impressive. The drop off in hit is notable as the batt charge gets low. Its particulalry noticable in TP mode. Not a biggy. I generally swap out the batt at mid charge anyway where it isnt so acute a problem. It will be interesting to see what busardo makes of it actually. It will be the first DNA40 'clone' he reviews I think...
Ah interesting, I'll have to see if I can spot that with my VF.
Yeah that will be an interesting review. I'm subbed to him on Facebook, and he was first sent something called the LVT-E or something like that, then he was contacted by Heatvape to tell him that this LVT thing is a clone of their Invader Mini, so he swapped them out.
I commented on that post on Facebook to muse philosophically along the lines of: "what is too much of a clone? The LVT is a full clone of the Heatvape. But the Heatvape, while an original design, does use a Chinese clone of the DNA 40. Where does one draw the line?" He didn't respond
But yeah I'd love to see scope readings for the ChiDNA 40 and the Heatvape is likely the only chance we'll have of that, for now at least. Shame in a way it's the 50 watt device as things might have changed a bit since the 40 watt iterations (though perhaps not much, based on what you said.)
i havent seen it jump into T mode but I have seen the reverse on wake up. The auto recognition of Ni vs kanthal is a bit flaky i think. I wish they hadn't bothered including it really. So I think you device is ok, just have be vigilant!Ok, just purchased this device on Thursday, keep in mind, this is my first external battery mod ( used to MVP 2, Istick 20w) I've noticed the off and on waking issue, and failure to remember settings, but last night, I was letting the battery run down to see if a single battery would last me all day, and it had been laying down and gone to sleep, when I woke it up, without checking the screen, fired it, and it had gone from my saved 7.5W in Kanthal to 10w and showing temp instead of voltage. Obviously this toasted my freshly built ( that morning) 1.4ohm coil is this behavior typical of this device? Did I do something wrong?
Thanks,

I saw this on Vapor Tek this morning and ordered it based on it being super rugged. Then, I read this thread. I probably still would have ordered it despite the glitches that have been mentioned. I have two iSticks, an original and a 30, and like them, but they always seem to need a charge at the same time.
This will also be my first experience with Ni200 and temp control. I've got tempered Ni200 on 28 and 30 gauge and will start out with an ElrK clone to keep it simple.
The chinese dna40 clonerd boards do not in general dispaly a TP message like the evolv-based devices do so fear not!!I've been using this for about 2 days now. Once I found out the manual was wrong (mentioned earlier re: entering Temp Control mode is NOT Fire + "-"), things have been relatively smooth sailing. I have noticed a couple times that it has reset to factory defaults (back to 10w and resistance shows "--", then asks if it's a new coil). I haven't had it switch between Voltage and Temp modes on wake up.
One thing I haven't noticed yet is the over temp message. Does it show up only while firing, and disappear as soon as you're done? I turned the temp down to 250 to try and see the message, but I didn't. It definitely brought the vapor production way down, so I know it was regulating, just didn't see the message.
Also, does anyone have a recommendation on where to set the temp? Or point me towards a better thread that I haven't been able to track down yet?
Rayon, being pure cellulose, has no "flavor" like cotton does. To me it seems to have superior wicking abilities and switching liquids happens very easily because of the fast wicking ability.
A lot of people say it is easier, more forgiving, to work with than cotton. If you have used cotton there is an adjustment to make in that more rayon is needed than cotton. That is a result of rayon contracting, slightly, when it gets wet versus cotton expanding.
Rayon seems to last far longer than cotton. I, typically, get 60 to 100ml from a build and some folks have gone past 250ml in a pinch.
This thread is kind of long, but it covers everything you'd ever need or want to know about using rayon wick -
