when it comes to ordering your first kit, i have one simple piece of advice... keep it simple. Yes the eGo twist batteries are nice, but if you have never vaped before or you dont know what voltage you want to vape at you may get frustrated with either burnt juice and wick, or not enough vapor to be enjoyable. its simple to adjust but could get frustrating to someone who has never vaped before.
The eGo C is a great system, i have never used them myself (still working on using up all of my eGo T atties first). i would suggest to go with the eGo T to start with, its more streamlined in that when the attomizer dies, you just throw the whole thing out and you dont have to worry about if you have put the new atty head in and is seated correctly. the tank feeding system is the same concept between the two though, and the T should be a bit cheaper to start out with as well.
There are other starter systems out there such as the iTaste by innokin (
Products / iTaste VV - Best Electronic Cigarette | New Ecig Starter Kit| E Cig Manufacturer), it is variable voltage like the 'twist' and is designed to 'hide' in your shirt pocket by looking like a capped pen. There are also systems that look like a traditional cigarette in size like this one (
AltSmoke.com | Personal Vaporizers | Electronic Cigarette | Ecigs | Volt - Standard Starter Kit - Starter Kits) but ones that have this form factor suffer from poor battery life and will need charged much more often than kits such as the iTaste and the eGo
As far as where to get your kit from there are more sites out there offering them than you can shake a used car mega lot at. its truly mind boggling how many vendors there are out there right now. I would say to not take one persons word as gospel and do your own due diligence and google search 'e-cigarette' and go from there finding vendors. they are not all created equal and over time you (and we all have) will have good and bad experiences just like any other online service. If you find a vendor you are thinking about, look in the threads here to see what others think about them and go from there.
The short and dirty rule of battereis is the larger the mAh (milli amp hour) rating is the longer the charge will last. in e-cigs they generally range from ~150mAh all the way up to and beyond 3000mAh. with this larger capacity the battery itself will obviously get much larger...
I dont know what the "Upgrade" model is, but the color is obvious and the twist allows you to twist the bottom of the battery to increase or decrease your vaping voltage (higher voltage shorter battery life... lower, longer)...
the head resistance is how much current the coil allows through the wire that is your 'head'. the lower the Ohm resistance, i.e. 1.8 Ohm, the more current the wire will have passing through it and the hotter it will get. this has a direct effect on how much juice you will go through, the lower the resistance the faster you will go through it and the higher the resistance the longer it will take to go through a tank. ultimately the choice is up to you, but most people i have talked to prefer the lower resistances below 2.0...
the tank color is simply the color of the plastic that makes up the tank, and the filling is your e-liquid or juice. you have the option with the kit you linked to of getting them empty or having them filled with either regular (tobacco) or menthol flavor at 18mg (18mg is the 'average' strength of a full flavor analogue cigarette such as a Marlboro Red or a Camel regular. 12mg is considered a light and 8 and below is considered ultra light. it is important to order the right strength for what you smoked because you dont want to get too much nicotine, its not pleasant to be sick off of. just keep in mind that you will generally get more nic out of an e-cig at the same level as you would an analogue since your e-cig doesn't burn out like an analogue would...
Yes, you can refill your eGo T and C cartridges with whatever flavor or strength of juice you like. you can buy pre-mixed flavors from 0mg up to 36mg. or you can buy your nicotine, dilutent and flavors seperately and mix it yourself. if you mix your own, the initial cost can be daunting but is cheaper than pre-mixed in the long run, and you can mix it up in whatever flavors you have if you decide you dont like the one you just finished instead of going through a full bottle of whatever flavor you ordered. just about every site that offers kits, batteries and atties will sell juice in one way or another.
a bit longer than i was intending. But I hope it helped you out some all the same.
