Great with a full battery at .5 with a dual build crown. Until the battery gets to the halfway mark. I am certain that the performance drains right along with the battery : ) The voltage is not capable of increasing above 3.2V at .5 Ohms and 50% battery left. 21 watts to 36 all indicated 3.2VDC. They get an A for cloning the form AND making it 18650!!! Its great for a nautilus all day long and hopefully the circuitry protects better than it amplifies. Time will tell but I finally got my ZNA, lol The Cloupor Chip is much better but thankfully I did not upgrade (T5). When it reads zero on the battery it will still give you 5 - 10 full strength vapes. Vapor Shark rDNA40 will be my next choice and I should be set, perfectly temped vaping ; )

Just a follow up on this device. Maybe I received a lemon but the performance (amplification) just plain old sucks! If you unthread and rethread the battery cap it will reset and you get a few more full power vapes. I looked for the product on the Tobeco website but was unable to find it. I wanted to send them an email inquiring about the horrid performance issues. I bought mine from Cignot but have not reached out to them as they are just selling what they were sold. I am becoming less and less of a Tobeco fan i must say based on other products as well. This zGripper ZNA36 definitely takes the cake though!!!
I've had the same exact issues. Going to replace the chip with a genuine DNA chip at some point. Maybe that will make it work properly.
I was about to do the same, but my father (which is an electronician) did some test on the device and it seems that the way the device is made, there's way too much voltage drop. There's too much threading and their poorly made. It also seems that Tobecco decided to use some really low grade material.
I wouldn't recommend you to do it.
I ended selling my black zgripper.

Oh wow...thanks for the heads up.
