I'm aware of that being an Electronic Test Tech for a number of years.

But as far as the settings are concerned when going back and forth between wattage and voltage modes you find yourself back where you left one setting like still set for 3.9v in the voltage mode after switching to the wattage mod and going up and down there without effect on the other setting. If you have a tank that is 2ohms at 12w you would be looking at roughly 4.9v on a tank that maxes between 4.2-4.4v.
One example is keeping the Vamo or other APV like the VTR set at 3.8v I can run at 10-12w max on the Smok Tumbler with the 2ohm coil in use while not constantly maintained either since that will cook the single coils used on those. Yet if I run the same tank on an eGo vv/vw type battery I can vape all day at 10w with a particular flavor. How do you figure unless the eGo battery is seeing a smaller current value. The max on those is usually about 2.5amps compared to the 10A on a high drain 18650 used in the VTR.
This is why I had to find out just what the H is going on in actual terms by ordeirng the Eleaf Ohm and Power meter to get the reading independently not by just the lcd display on battery or mod. Those generally provide just the basic info not the actual under load you are seeing.Smoktech has a new ohm/power meter gadget out now as well.

I noticed that while there but was also looking at the Innokin product page as well as checking around for any pre[order pages and naturally running into all the wholesale sites! I would say whatever does actually come out from Innokin will prove itself as being a bit more durable since I've had the 2.0 now for over a year without one glitch! The same has been seen for the four VV v3.0 700mah batteries while I still prefer more mAh power especially for the larger tanks!
Hey ScandalLeX I won't needing that one since I have another 30watter due in soon also seeing a flashlight as well.

That one is 18650 powered however which I still tend to prefer while the iStick other then the flimsy locking method on the Bending Adapter as it turns out has been a great little brother mod!
