Hi pbxbelmar, Just because you can turn it up doesnt mean you have to. Thats a nice looking device and I see it goes as low as 5W which is very low, I usually run around 8W when using a VW device with a 3.2ohm cartomizer though I tend to vape pretty low with long slow draws.
Yes you will burn up a cartomizer if you apply too much power to it, this is the same as with any coil though in that you have to match the power/resistance and liquid flow to create a satisfying vape.
