oh my head hurts from reading your first post. you arent going to get great power from the cig-alikes. the two kits you bought are probably the same type of batteries or at least close to the same mAh. (same size batteries) they are the same type of kit. so you have more batteries but 1 kit is probably not better over the other. Thats the problem with all the advertizing. 1 company says "OUR KITS ARE BETTER THAN COMPANY Y'S KITS" when in reality, most cig-look-alikes are the same thing or at least very close to being the same.
There is ONE cig-alike that is regulated at 3.7 volts (less battery life, more battery power) and that is the KR-808D also known as the VOLT and the BLOOG. The VOLT and the BLOOG are both KR-808D batteries. The 510 mega-T is also regulated at 3.7 volts but they are harder to find, not a lot of vendors are carrying them. Anyway, the Volt and Bloog are good for power but they are still such small batteries. You have a couple options, and its completely up to you.
1. You can stick with the kits you have now (i'm guessing you have four regular 510 batteries from the 2 kits? If you decide to stick with these little batteries then at least look for a PCC (personal charging case) that way you can keep batteries charging while your out of the home. The case will charge a battery while its in your pocket while the other is used or kept outside the case.
2. OR you could sell these two kits in the members classifieds area of this forum. Some people with bigger mods are looking to get a few regular 510 cig-alike batteries for nostalgic reason, or to use when they are at a casino or a party where they'd be embarrassed to use bigger mods. You may have luck selling some of your batteries in there. You'll just have to get your paypal verified here.
3. IF you decide that those little batteries are just too weak and a waste of money (a lot of us do) you can go with something a little bigger, or a lot bigger haha. You can go for the VOLT or the BLOOGs but like I said, they have bad battery life. OR you could go with an eGo kit. The eGos are fantastic they give ya great vapor and good battery life. They even have variable voltage eGo kits that you can use with ANY OHM cartomizer or atomizer. (there are different ohm cartos and attys for higher or lower voltages) See the little cig-alike batteries youve got now probably came with high ohm cartomizers because thats all they can handle. With an eGo you can get lower resisted cartomizers, with a variable voltage eGo you can up the voltage and use your higher resisted cartos until they are dead! (and the vape will BE MUCH BETTER) The variable voltage eGos are called "eGo Spinners"
4. You might also be interested in a bigger battery mod. If you have the money, you can spring for a Provari, sure. Provaris are variable voltage and they are an artisan product, so, naturally they are expensive, but they are also high quality. There are cheaper vvoltage devices that work just as well, such as the Vmax or the Zmax or the Lambo or the Young June. All great choices for a beginner. The DARWIN is a ridiculous choice. They are selling upwards of $400+ and there are cheaper devices that do the same thing lol. The darwin is now a collectors piece. The Zmax does everything the Darwin does and you can get a new Stainless Steel Zmax for $120.00. The Zmax is variable voltage AND variable wattage, so once you tell it how u like to vape with 1 carto, it will automatically set itself to know what to set itself at when you buy new cartomizers. Wonderful for n00bs to vaping.
Another road you could go down is the simplicity road. Get yourself a madvape's BOLT, an Altsmoke SILVER BULLET or ALPHA, or a Smoktech Telescoping mod. These are FIXED voltage mods that you can use low resistance cartomizers with. Wonderful vape and this is actually my preference for out and about. (and at home for now as well haha) I use eGos at places like Bars and the Grocery Store, and I use my big battery devices at home or at a good friends house. Its good to have a small battery kit (volt/bloog or ego) and a big battery like the variable voltage devices or fixed volt devices i listed above.
If you really get into the HOBBY end of things, you can get into rebuildable atomizers and genesis mods but don't even bother looking those up at this point, your still starting out and those are more hobby based. If you HATE dripping into your cartomizers then I HIGHLY recommend getting yourself a CARTOMIZER TANK, or three, lol. These are tanks that hold PUNCHED (cartos with holes in their side) CARTOMIZERS. As you suck, the juice gets pulled into the cartomizer's hole, and in that way, you only have to fill the tank here n there. You could also get a nice big clearomizer, like a Kanger or a CE6 or whatever.
I recommend you take everything I just said into consideration, go to a big vape superstore like madvapes, look for all the names of the things I mentioned (google volt and bloog because madvapes doesnt sell those.. although they do have the 510 mega T.. But I really recommend getting an eGo rather than a VOLT/BLOOG lol) aaaaaaaaaaaaaaaaaaaaaaaaand just look around.
ALRIGHT. I feel thoroughly insane for 1. knowing all of this and 2. typing it all out just now. SOO i'm gonna go take a bath and shut up. Hope I helped. Bye.
