Well, I went looking for another advert that expresses the resistance of the atomizer and found it here:
JOMO Tech E-lite 40w Kit
It says it has a .5 ohm atomizer head. Firing at 40w, no matter what, it will need charging fairly quickly. If you are drawing ONLY once or twice an hour, it may last... If you are using it as a replacement for smoking, I hope your juice has enough nic to satisfy you when only vaping that few draws.
Like my smoking, I tend to vape more if I am doing certain things. I vaped more when drinking, socializing, sitting...things to think about.
For me, I see it as a minimal and inflexible answer. It works one way and gives no options.
I would consider a variable wattage kit that has a replaceable battery. When one battery is recharging, another is used. OR, buy two kits.
Hope helps you find what is best for you...
