It also has to do with the size threads too, as to what you can get to put on the battery. The thinner 808 series, like the volt are rather limited in after market attys/ cartos/ tanks. Tbe Ego (Riva/ Kgo) all use a 501 series thread and is probably the most popular size. It certainly has many more options as to what type of things you can add to it.
An atty (atomizer) is the part that gets hot. They also require a cartridge to hold the liquid. A cartomizer has both in one unit and are easier, less messy to fill. I don't have any tanks yet so I can't really say much about them except what I've heard about them leaking, not giving good vapor or a strong throat hit. I prefer cartomizers since they usually hold more liquid and are easier to fill and less messy.
To not confuse you, the eGo/kGo/Riva etc has 510 threading, not 501. Its is the most popular and like stephpd said, has many options for attys and cartos.
I also have gotten the E-Power and like it for the same reasons. Also picked up a variable voltage mod from Madvapes for a fair price. It also uses standard 14500 batteries (E-Power using 14650) and they all charge on the same charger. All using, for the most part, the same attys and cartos.
Still experimenting with juices and hope to be able to come close to a few of my favorites DIYing the liquids. Got some PG, VG coming in the mail next week and have a few flavors to add to them. Until then I got a delivery today of my favorites from Vapor Station to hold me through the holidays.
Best thing though is less analogs. I haven't quit yet but down to 1-2 cigs a day verses 1-2 packs. Probably could quit totally now but still have 4 packs left and can't see just trowing them away. I wasn't sure if these E-cigs would actually work. I've tried many of the other methods of quitting and they never worked. E-cigs giving me lots more psychological reinforcers that the others lacked. (vapor, something to hold, put to my lips, deep inhale, etc) Eventually cutting back on the nicotine.
Congrats Bambie! Dont beat yourself up if you have a cig or 2. Just cause you got your PV doesnt mean you will stop right away. Most people will wean off. The less cigs you smoke the more your tastebuds will come back and after alittle thats when most people really start to think cigs taste like crap and stop completely. So keep going your making awesome progress!!
I would refill your cartos when the flavor and vapor starts to drop off some. You dont want them to get too dry so its never a bad idea to just keep topping them off. For how long they will last it all depends. They are made to be disposible. The juice your using will affect how long they last. Some people only get a few days out of one and some a few weeks. I use the Ressurectors and get on avg 2-4 weeks from one, but thats pretty long. If you get a week to ten days thats not bad. Normally people switch to a new one when it starts to loose flavor or it starts to clog up. When your not happy with the airflow anymore, switch to a new one. The more you use your ecig the better youll get with it. It will become easier to know when it needs a refilling and a new carto, etc. VG dulls flavor and TH some so thats why your not getting as much with 100%VG juices. PG gives better TH and flavor, but doesnt produce as much vapor. Thats why people normally like a combination of the 2. Try 80%PG/20%VG. Thats a popular ratio that gives good TH but still produces good vapor. A higher nic % will also give some more TH. I would try the 80/20 first and then if thats still not enough, try upping the nic %.
If you want to know when you should change your battery you could get a multimeter. Then you could see what its at and could throw it back on the charger when it gets to around 25%left. You can get the one madvapes sells on ebay for $3-4 bucks. Its not a bad deal at all and works well. Youll be able to check the ohms of your cartos too so you can see what their really at. That will help you catch DOA ones too so you dont waste juice.
You shouldnt have to drag on your ecig really hard. Do you have a manual or auto battery? The manuals are nice bc you can push the button a second or 2 before you take a drag to warm up the atty and create some vapor.
Goodluck and keep it going!
Ok. The Volt will give you a warmer vape than a regular eGo. The battery doesn't last as long, however. You might be happy with a PCC to keep that battery charged if you haven't already got one.
I usually recommend a Volt to the American newcomers because it's priced relatively cheaply and performs well. But, it's a KR808D-1 model and there are lots of vendors for kits and accessories.
When you're ordering juice, a good mix is 70% PG / 30% VG. 100% VG is like syrup and it takes longer to wick properly. You'll also get more throat hit and more flavour with PG.
You may find there are certain times of the day when you need more nicotine. Like first thing in the morning. If you're normally ok with say 18mg, you might consider having a cartomizer filled with 24mg for those certain times of the day.
Your cartomizers are about 1.5 ml. They can hold about 30 to 35 drops of juice easily, but you have to work that juice in there. I just drip down the side away from the center hole and then shake the carto like a thermometer to work that juice into the filler so I can drip some more. When the top of the carto looks like a slushie and stops soaking up juice, you're done.
Your cartomizers are meant to be disposable, that is they're only supposed to work until you run out of juice the first time. However, if you keep them wet, i.e. periodically top them off before you vape them dry, you may be able to keep them working for quite a while. If you get a burnt taste from them, however, they're done.
When you're vaping, just take a slow easy drag. A hard pull, like you would use on a cigarette, doesn't really work for e-cigarettes. Breathe in from deep in your chest if you need to take a long drag, i.e. longer than 3 seconds. Breathing in hard doesn't help, but keeping your inhale going longer will get more vapour into your lungs. If you run up against the 5-second cutoff with no satisfaction, try stopping mid inhale and then continuing to get a longer vape.
Cdnvapor.ca has KR808D-1 (aka 808) accessories if you're interested. HappyVaper is also a great source of supplies, but they sell Bloogs (808), which are pricey.
I think you just need to ask more questions about your current kit and juice before diving into yet another kit. It sounds like your problem isn't so much that you need an eGo right now, but that you may still have a few misunderstandings about making the most of your current kit.
