Thanks for the reply guys! The temperature thing is really just for added flexibility, and because I don't want to be artificially limited. While it totally makes sense to make the vape "n00b proof" I think its important that it also have a little more flexibility in its capabilities (the flexibility of the extreme is what drew me to it in the first place). I really respect a company that makes a product that allows their end users to make some very poor choices with their equipment, and until I hear about some way of cranking the Extreme up to somewhat absurd temps, I think I'm gonna have to hold off. Honestly I expect its a limitation of the heating element, but I may be wrong. And thanks for the info on the power adaptor. The inverter I keep in my car should be able to handle that fine, as it handles 200W, above the about 180W the Extreme is indicated as capable of drawing, but I suspect rarely does ( Watts = Volts * Amps). I suppose a more efficient method would be to just amplify the car's 12V up to the required 19V for the vape. While I know how to do this in lower power situations, I'm not sure if something I could build now would be able to handle the kind of power need by the Extreme.
