ok, i found nicotine nirvana. the difference between the skinny 250mAh batteries with prefilled cartridges and the higher voltage machines with a liquid tank is night and day, a whole 'nother world. i should've listened to jth, frixxxx, and other friends who told me right at the start. instead i had to figure it out for myself, but figure it out i did! this setup rocks!
a 650mAh or better joye tech battery with a kanger tank and some eliquid is all you need. instead of trying to suck molasses through a straw, you can get a hit that will knock you on your a** and make your eyes water. woo hoo! heaven!
from an engineering perspective, what an elegant solution. 4 simple parts: tank, tip, screw on base, and atomizer. only the atomizer is a consumable, they are cheap, and there is a variety of ohms to help dial in your preference. kanger evod2 or evod glass is the way to go for me. so simple and robust, brilliant!
i got the 1000mAh battery which is about 1" longer than the 650mAh battery. also the twist variable voltage option adds another inch, the unit is over 7" long. that is overkill, but i didn't understand from the internet pictures without the benefit of expert help in person. the extra mAh adds time to length of use charge but uneccessary and unwieldy and don't add any more kick. just get 2 650's, each is plenty to get through a work day. the bigger ones are perfect for car commute or home, they just go and go. the variable voltage from 3.2 to 4.8 does increase kick, but not really needed.
different voltage settings change the flavor profile of different flavors. i had been switching between a mellow 'red' flavor and a harsher 'sahara' flavor but they taste different through the tanks. the sahara at 4.0 made me choke and cough like cheech and chong. the red at 3.6 is great, almost an exact match for what i was trying to replace, but just fine at 3.2 volts also. if you want to quit smoking take $125 and get 2 650mAh batteries, a usb charger, 4 kanger evod tanks, 8 spare atomizers, and a bottle each of an american and a turkish tobacco mix liquid. you will never look back.
i got them in black and stainless colors. the black one looks like a magic wand with silver tips. it is big, so is the stainless one. i only use them in the car or home because i don't want to be seen sucking on a big black or shiny unit out front at work. i feel like john holmes but look like harry potter. i always wondered what john holmes felt like. wait, that didn't sound right. i always wondered what it would feel like to be john holmes. yeah, that sounds better.
who cares, i'm all nic'd up, this ecig setup is da bomb.
