The DNA 200 does not leave anyone in the dark. Its a regulated mod. The max voltage output is 9 volts. It has an extremely low minimum resistance before it pops up the short error. I don't remember what it was, I think it was Pbasardo that tested it but it was lower then .05.
From a purely technical aspect, as long as it fires and does not display the shorted message it will fire up to a max of 9 volts or 200 watts whichever limit is hit first.
Forget about what anyone has said about this chip and read the specs. Its all there. It is a little vague about the minimum resistance. otherwise all other info is clear.

Not sure why there's a trend to build to MAX out your device, all this equates to is VERY bad battery life.
If your cloud chasing then your trying to brute force it. There is an art to tweeking your builds. seek balance in all things in the set up for maximizing cloud production.
The same thing goes for the vapor that just likes a hot vape. 150+ watts and a Dangerously low resistance build is not required and is terribly inefficient.
