I am not a user and the Jury is still out on whether I am a fan...I have never used one that was made properly I guess. I did see one the other day that worked REALLY good, but Im pretty sure I dont have the patience to build one that requires that much fiddling...I also don't think that you need to vape anything at 20 watts.
As I was explaining to a guy the other day...When someone calculates the watts on their device and thinks they are vaping 15 watts (because thats what the theoretical math tells them) that doesn't necessarily mean that they they are actually getting 15 watts to the atty. When you have a Power regulated deevice giving you 15 watts instantaneously you may find that things are different.
So if you set up a Genesis properly you dont need anything but a standard 3.7 battery. The ones I was using the other day were using 18350' and 18500 batteries and they were working FABULOUSLY!
Yeah I agree, but I still want a Darwin! I like the form factor. And it would seem the form factor of being able to keep the genny upright while not used and not worrying that the pv itself won't tip over if bumped or anything.
